Are you planning to buy a refrigerator and looking for energy saving options? If upfront cost for buying is not a concern for you then do look at refrigerators with inverter technology. Rest assured that the extra money you pay upfront will be recovered in the form of electricity savings. Inverter technology that was developed in Japan is the most efficient refrigeration technology available in the market today that can save up to 30-50% electricity consumed (units consumed) compared to regular refrigerators available.

How does a refrigerator work?

Whenever it is hot and we want to feel cooler, if we take a bath, we suddenly start feeling better. The moisture (or water) on our body evaporates by taking heat from our body and makes us feel cooler. Similarly in a refrigerator there is a refrigerant called HFC (Hydro Floro Carbon) that moves in the pipes or coils on the rear part of the refrigerator. When it is in a liquid form, it takes the heat from the refrigerator contents and evaporates to form gas there by cooling the things kept in the refrigerator. The gas is then compressed using a compressor to convert it into liquid again, and the cycle continues. The compressor uses electricity to do its job and is the most electricity consuming part of a refrigerator.

Refrigerator also has a device called “Thermocouple” which senses the temperature inside the refrigerator and makes the compressor go “on” or “off”. The thermocouple works as per the temperature set in the refrigerator (yes you can set temperature in a refrigerator as well and we will explain it more in our other articles on refrigerators).

How does a compressor in regular refrigerator work?

Most compressors in regular refrigerators are single speed refrigerators. They are either “on” or “off” based on the temperature in the refrigerator and the setting in the thermocouple. Most compressors are designed to handle peak load conditions (for high temperatures in summers), which means that they run at peak load even in winters when the cooling requirement is less. Every time the refrigerator door is opened, heat enters the refrigerator and the compressor has to take care of this load as well. So most regular compressors are built to take care of peak load plus the “door open shut” load which during most of the year is much more than the actual requirement.

How does a compressor with inverter technology work?

A compressor with inverter technology works very much like a car accelerator. When the speed required is more, the acceleration is more, and when it is less, and then the acceleration is less. This makes sure that during summer months when cooling load is more, the compressor works at peak capacity taking more electricity. But during winter months when cooling load is less, the compressor works less there by consuming less electricity. Even in summer month, the night temperature is less than the day temperature and thus electricity savings happen in night when compressor can run at a lesser speed.

This kind of compressor never switches off even when the temperature stabilizes, but runs at a slower speed maintaining the temperature inside the refrigerator. The benefits are:

  • In an “on” “off” cycle of a regular refrigerator, inside temperature varies throughout. But in case of inverter technology, temperature is more stable.
  • The amount of noise made by the refrigerator is much less in refrigerators with inverter technology as compared to the regular ones.
  • Energy or electricity consumption is much less when the temperature stabilizes.


Although prices of inverter technology refrigerators are on a higher side, but they can save a good amount of electricity, there by helping you recover the money in your electricity bills.


Lesser known benefits of Inverter Technology

  • Regular motors need 3-4 times more current (more than running current) at startup. So the inverter/generator size needed to run any AC or Refrigerator increases significantly. But Inverter Technology air conditioners and refrigerators have variable speed motors that start up gradually needing much lesser current at startup. Thus the size of inverter/generator required to startup is less. For e.g. A 1.5 ton fixed speed AC that runs at about 10 Amp current may need up to 30 Amp current at startup and thus a 5 kVA inverter/generator. But an inverter technology Air Conditioner needs about 6-7 Amp current and not much more at startup and thus a 1.5 kVA or 2 kVA inverter/generator is good enough to support it.
  • Regular motors have much lower power factor. In commercial and industrial connections there is penalty for low power factor and rebates for higher power factor. An inverter technology motor will have power factor close to unity (or 1) which not only results in lesser electricity consumption but also help get rebates on better power factor.
  • If you are planning to use Solar PV for air conditioner, then it is the best to use inverter technology air conditioner or refrigerator as it not only reduces the size of PV panels because it consumes lesser electricity, it also reduces the size of inverter to be put along with the PV panel.

    Can I get your suggestion for selecting a good brand (excl Haier) 300L (+/- 25L) refrigerator with bottom freezer & inverter technology compressor & good service in around Kochi, Kerala? I see from net only large ones (500L) with this spec.

    • https://www.bijlibachao.com Abhishek Jain

      I doubt that there are any brands (other than Haier) that offer bottom freezer with inverter technology in 300L size range.

    • J Philip

      What are the models from major brands with next few sizes (400 +/- xx) in bottom freezer with inverter technology?

    • https://www.bijlibachao.com Abhishek Jain

      Panasonic NR-BW415XS and Panasonic NR-BW415VN are 407 lts models with bottom freezer and inverter technology. These are closest to 400 lts that I know have bottom freezer and inverter technology.

    Can I have your views on comparison of Samsung Smart Convertible 5-in-1 with LG Smart Inverter 3.0 in a 400L size refrigerator?

    • https://www.bijlibachao.com Abhishek Jain

      Are you looking for a convertible refrigerator or no? The energy consumption comparison that you see on BEE data is in regular mode when both freezer and refrigerator are working. But the best part about smart convertible refrigerator is that you can just use the freezer, or just the refrigerator, or just the freezer part as refrigerator. There are so many modes that can help you save electricity if a particular part is not in use.

      If one of the part will mostly remain off (throught the year), then it is better to buy a smaller refrigerator. The 5 in 1 feature helps only if you go out of your home frequently. Otherwise if you plan to use both the freezer and refrigerator in regular mode, then I think LG has more energy efficient refrigerators. Also even LG has some models with smart convertible features.

  • ashok

    can i buy samsung rr19k173zdz/hl/2016, is this model contain inverter technology..

  • Vivek

    Thanks to the list of energy efficient refrigerators in your website, i was able to shortlist on a few LG and Samsung models that satisfied our family’s need. I ended up buying a Samsung refrigerator – Model RT37K3763S9. Though it features an in-built stabilizer (110-300v range – also showcased with a sticker on the door) and inverter technology, the technician who came for installation insisted that i buy a stabilizer due to possible voltage fluctuations.
    I read your comments below on voltage fluctuation and Surge that confused me a bit. Assuming the In-built stabilizer takes care of the fluctuation, does it still make sense to get a V-guard stabilizer just so that it protects it from the surge or will the in-built stabilizer take care of surge protection too. Also considering Samsung providing warranty only for 1 year for all parts except the compressor (which is 10 yrs), should i anyway think of a stabilizer just to be safe. Long story short – how good are these in-built stabilizers – can they be trusted enough considering that they are a relatively new technology in India?

    • https://www.bijlibachao.com Abhishek Jain

      It is not a new technology in India. In-built stabilizers or SMPS have been used in various electronics for ages. Even you laptop has it, your computer has it, your TV has it, and most electronics have it.

      A lot depends on the power quality you get and the kind of wiring you have in your house. I live in Mumbai and I also have a Samsung inverter refrigerator. I have not put any stabilizer because there is no need for it. Power quality in Mumbai is good. Wiring in our house is good and we hardly get any short circuits, etc. There is no need for stabilizer.

      Also VGuard stabilizer is not a great surge protector. You can get better surge protectors from companies like Belkin. And otherwise you do not need a stabilizer for the refrigerator as SMPS in it can easily handle it.

    • Vivek

      Thanks for your response. really appreciate your efforts to answer our questions…

  • Vikas

    I have Samsung fridge rs21hstpn1 need stabilizer. As i know it comes with in built Stabilizer to save from power fluctuation. But recently the fridge stopped cooling, when we called the Samsung Guy he says because of voltage Fluctuations the compressor has gone faulty, the replacement cost for which is INR 10K. My question is do we still need to have a stabilizer with this model and does the compressor cost that much?

    • https://www.bijlibachao.com Abhishek Jain

      Hi Vikas,

      There are two types of fluctuations that happen:

      1) Regular voltage fluctuations when the voltage goes down or lower than 230 V. These are not sudden, and rarely do voltages go up to say about 260V, but then the refrigerators can manage between 110-290V.

      2) The other kind of voltage fluctuation is called a surge, where voltage shoots up suddenly due to an incident. The incident can be short circuit, or lightning strike, etc. Here for a short instance the voltage suddenly shoots up beyond acceptable range. For this one needs surge protection.

      Now a question for the Samsung Engineer would be: “Why did the refrigerator fail if it says stabilizer free operation?” …. if he says surge was the reason …. then yes it can certainly happen. But if he just says voltage fluctuation, then he has to explain why it is mentioned stabilizer free operation.

      Compressor may come costly.

  • Sarika

    Hi Abhishek ,
    First of all u and your site is such an inspiration ,
    I have ordered for LG GLT522GNSL.. 470ltrs range, refrigerator after i researched ,i m happy its no 1 in bijlibachao list too. i can pat my back that way ;-)
    I just wanted to know 2 important things
    1) Does it need Voltage Stabilizater , if yes which will be best considering the technical specs.So that stabilizer consumes least power
    2)i was not able to figure out if this fridge can stay cool in event of power cut, as i believe that if i use inverter or generator either , electricity is still consumed .. let powercut be a time to save electricity and use stored electricity. Im wondering if it has power cut ever cool or cool pad technology whig lg provides, can u clarify this .

    Thanks .. and keep up the really fantastic work.
    Btw i shifted to all power and water saving appliances :-) , inspired by ur site and by seeing how we are spoiling the future… lets be wise

    • https://www.bijlibachao.com Abhishek Jain

      Hi Sarika,

      Here is my response:

      1) It does not need voltage stabilizer as its input voltage range is 100V-290V. It will function well at any input voltage within that range.

      2) I do not think that this model has cooling pads. So I doubt that it can store energy. But whatever said, stored energy is still “energy”. You use it from cooling pads or you use it from inverter. The efficiencies of the two systems (cooling pad and inverter) may vary and I guess cooling pads should be better. But the difference would be marginal. But yes it is better to have cooling pads, but then if you do not have it, inverter would also work.

      I am humbled to know that this site inspired you to do better for the future :).

  • Malathi

    Hi Abhishek, Between LG and Samsung 600+ litres which is a good buy? In terms of after sales service which one is better? Does LG run into repairs. My loyalty is with Samsung but the salesperson was plugging LG. Ideally looking for sturdy, durable fridge in 600+ capacity for long haul. Look forward to your inputs

    • https://www.bijlibachao.com Abhishek Jain

      Samsung has more energy efficient models in 600+ liters. You can look at Samsung RT61K7058SL/TL … Their Smart Convertible refrigerators have fantastic options to switch of part of refrigerator when not in use, or switch freezer to refrigerator if freezer is not needed. All this saves electricity.

  • Laxmi

    Hi..can you please suggest me which brand should I go for between BOSCH and Panansonic in 400 + ltr capacity. And if Panasonic, then should I go for Econavi or the manual model i.e. NR-BW465XS or NR-B2465VN

    • https://www.bijlibachao.com Abhishek Jain

      Hi Laxmi,

      Of all the brands and Models you have listed, I would recommend Panasonic NR-BW465XS. The reason for that Inverter Technology is the most energy efficient technology available in market today. Bosch does not have inverter technology models and thus even their two door models (which are rated by BEE on star rating) do not rank high in BEE star rating. This specific model from Panasonic has Inverter Technology as well as Econavi (both of which are great technologies). In general multi door models are not rated by BEE on star rating and thus manufacturers do not publish much data about them. But any inverter tech + econavi refrigerator would be good and efficient.

  • preeti

    Plz suggestion lg and Samsung witch one is best refrigerator in 192 ltr. service quality of both the brands is very good in our area

    • https://www.bijlibachao.com Abhishek Jain

      Hi Preeti,

      If you are looking for energy saving options then both LG and Samsung have good models. The biggest benefit that LG models in this range have is that they have “Evercool” technology that keeps refrigerator cool even during power cuts. If you face a lot of power cuts then LG would be a better choice. Samsung also has a cool pack, but it is only there in the freezer section. LG has it for the full refrigerator. Otherwise you can look at these models

      LG GL-B205XSHZ
      LG GL-B205KPZN
      LG GL-B205KSLN
      Samsung RR19J2835RX/TL
      Samsung RR19J2835LX/TL
      Samsung RR19J2835PX/TL
      Samsung RR19H1835LX/TL
      Samsung RR19H1835PX/TL
      Samsung RR19H1835RX/TL

  • Robby McCarrell

    How can I know if a Samsung refrigerator has this or not? I am considering model RF28HDEDPWW.

  • Subina

    I would like to know
    (1) the difference between smart inverter and digital inverter.

    • https://www.bijlibachao.com Abhishek Jain

      Smart Inverter And Digital Inverter are the same thing. There is no difference.

      I think Multi Air Flow would be better.

  • Joliverio

    Hi; I kindly ask your comments about my current situation: I am living in a country now that the Voltage and Frequency are 220Vac/50Hertz and next month I will move into another country that the voltage and frequency are 220V/60 hertz. I have one fridge “Panasonic Inverter” and one Panasonic “Washing Machine Inverter”, both of them shows in the user Manual that the products are 220V/50 Hertz. Because I am moving into another country which voltage is 220V/60Hz; do you think my Fridge and washing machines can work there? It is necessary to change something inside to make it possible to run @220V/60Hz? Many thanks for any help

    • http://www.bijlibachao.com Abhishek Jain

      Let me confirm that you are having a inverter base refrigerator and air conditioner. In inverter base equipment, the AC supply is converted into DC and than to variable voltage and variable frequency supply as for the AC load demand. With higher frequency also, it will first be converted into DC only. The equipment shall function ok in other country having frequency of 60 Hz.

    • Joliverio

      Many thanks for your reply! It is nice to hear that my equipments shall work under 60 hertz and same voltage. I have a refrigerator and a laundry washing machine with dryer feature (not air conditioner) with inverter technology

  • Ramachandra Nagarakatte

    Hi, Does the inverter technology refrigerators also work on inverters? Ie when there is powercut and inverter is on, will invertter be able to take the load of refrigeration?

  • Piyush

    Hi, I have a Bosch KDN46AI50I refrigerator with 400l capacity working in 220-240V range. The power supply in my apartment is erratic (keeps going on and off), which is exaggerated since there is power backup, making it more erratic. Can you please suggest if i need a voltage stabilizer, and if yes, how should I choose a voltage stabilizer / cut outer. What would be your recommendation?

    • http://www.bijlibachao.com Abhishek Jain

      Hi Piyush,

      Power cuts do not cause voltage fluctuations. Are you observing fluctuations in your area? To choose a voltage stabilizer you need to know: 1) How low/high does the voltage fluctuates 2) The appliance power consumption. Number 2 can be found from your refrigerator model no/manual. But 1 needs to be determined. However as I said, just power cuts do not cause fluctuations. Supply side issues cause voltage fluctuations.



  • Pankaj Thatai

    Dear Team,
    I have recently purchased side-by-side refrigerator LG Refrigerator Model No GC-B207GSQV having INVERTER LINEAR COMPRESSOR, since I am living in a housing society & getting power at 11 KV for distribution. I hardly see any voltage fluctuation in distribution supply. So I am really not sure whether the above model is designed for voltage stabilizer FREE operation or not. Moreover on asking LG engineer, he informed that there is NO NEED for voltage stabilizer in this model but their dealer asks for dedicated voltage stabilizer for this model. Several reviews says on side by side refrigerator gives negative feeling about this technology (linear inverter compressor). Really confused what to do or what not to do?? Please suggest whether I need to install stabilizer or not, considering very rare voltage fluctuations.

    • Bijli Bachao Team

      You do not need a voltage stabilizer for this model. Most refrigerator models in the market have a stabilizer free operation. And on top of it, inverter technology does not get impacted by low voltage. So you need not worry about it.

    • Ravin

      an you share some details about this cut outer mentioned by Pankaj

    • sajeev

      You need a “cut outer” unit which can cut out your supply incase your voltage abnormally increase or reduce and also a delay unit incorporated so that a sudden power off an on condition never makes the compressor off and on suddenly. company like “v-guard” is marketing like this “cut-outers” for fridges.
      Stabilizers mostly have all these features built in and additionally voltage increasing and reducing function which is not required in your case. Because of two reason 1.stabiliser costlier than “cut-outers” 2. Stabilizers consume electricity whether it is used by your fridge or not and it is not that less, It amounts around 10 watt x 24 hours x .365 days
      And cut-outer is a must in indian condition where you can expect even 440 v sometimes and also as low as 90v

    I would like to buy a refrigaretor of 190 Ltr (Earlier it was available 165 Ltr but now it is not available).
    What is direct cool and forst free.
    My target is for minimum unit consumption so less enegry bill and thus I will be a part of your mission of billbachao.
    I have visited your site throughly and found Videocon VZ 207 which is direct cool and it is 190 ltr and it’s unit consumption is 135 unit / year as mentioned at your site. Another one is LG GL-D292JPZZ which is frost free and it is 258 ltr and it’s unit consumption is 190 unit / year as mentioned at your site.
    For which pattern I should go for direct cool or forest free.

    Now problem is that I may not be able to buy Videocon model as steted above because Videocon deler is not there in our town named Mehsana, which is situated in north gujarat.

    Further the purpose of this refrigaretor is as below.
    My mother stays at this town and she is alone. She some times comes with us at city Ahmedabad to stay with us. But as we are staying in flat / appatment system she is not feeling comfortable there. Thus she stay for 15 days with us and go back and again stay at our town for two months and again come with us at city and so no cycle is going on. She is 75 plus age with sound health of her age group and she can manage to stay alone at our town.
    At present we have Voltas refregarator at Mehsana which is too old and but working. We want to dispose it off and would like to buy new one for my mother.

    This is the situation for buying refrigaretor. So please advise direct cool or frost free, 190 ltr or 258 ltr.
    After studying purpose and use of refrigaretor If you perticularly suggest pattern forst free or direct cool with brand and model number then I will be the happiest person. In inverter technology is available in these small segment ?

    Thanking you in anticipation.

    Sincerly Yours

      Hello Mr Paresh,

      We have explained Direct Cool and Frost Free quite well in our video: https://www.youtube.com/watch?v=WXRdfaHSfJw …. you can check the same and you will get a lot of idea on which one would be better.

      I think for a single person 190 lts refrigerator would be better. It will save electricity as well. You can only get direct cool refrigerator in sub 250 lts range. While frost free is better in above 250 lts range. So a direct cool would be better for you.

  • Mahua Dasgupta

    We are comparing between a Samsung 320l and a Haier 320l. Both use DC inverter technology. Samsung is top mounted and Haiee is bottom mounted. Does a top mounted refg save more energy? If so, why?

    • Bijli Bachao Team

      Hi Mahua,

      A lot depends on the design of the refrigerator and a bottom freezer model can be more efficient than top mount model. In India there is no energy efficiency standards for bottom freezer models and thus the data is not available to compare. But internationally it is seen that in general bottom freezer models are less efficient as compared to top mount models. The reason given is that the compressor in most modern refrigerators is at the bottom of the refrigerator. Compressors are motors that release heat when they run. And that heat can impact the cooling of the freezer (in bottom freezer models), thus resulting in more energy consumption.

      To be safe top freezer model of BEE 4 or 5 star would be good for you.

    • Mahua Dasgupta

      Thank you team..I understand that the top mounted fridges technically have more energy eddiciency. However, In the first line of your reply you mention that bottom mounted can also be more efficient. In what way?

    • Bijli Bachao Team

      Hi Mahua,

      Efficiency of refrigerator will depend on the design of its condenser, compressor and other parts (like internal lighting), etc. That is why some refrigerators are BEE 1 star and some BEE 5 star. So if you compare the bottom mount refrigerator with inverter tech to a BEE 1 star rated top freezer refrigerator then you will find bottom mount refrigerator to be more efficient (as the design elements are efficient).

    • Mahua Dasgupta

      Thank you team. More specifically, with your qualified help, here are the models I have been able to narrow down to – Haier BMR 320l 4* 265 units per yr usage and Samsung 321l 4* 261 units per yr. The differences are Haier is bottom mounted and has “full DC inverter compressor” while Samsung is top mounted and uses “Digital Inverter” technology. Can you help me understand the diff between DC inverter compressor and digital inverter technology? Also suggest pros and con’s (apart from regular pros of a BMR).

    • Bijli Bachao Team

      Hi Mahua,

      BMRs are not rated by BEE on star rating. BEE is only rating TMR currently. So 4* rating for BMR sounds strange. However if Haier itself is stating 265 units per year then there is no reason to doubt them because most numbers are self reported by manufacturers. Now DC Inverter compressor and digital inverter technology are one and the same thing. Based on the numbers and convenience of BMR the Haier model looks better in this case.

    • Mahua Dasgupta

      Thank you team, your response helps me. But you had mentioned earlier that in long term top mounted ref are marginally more efficient than same.volume BMR. So we thought Samsung would be more efficient. Also which fridge is better in longer term considering we do not plan to change the fridge in future.

    • Bijli Bachao Team

      Hi Mahua,

      We did not mention “long term”. What we mentioned was that in general TMR should be more energy efficient than BMR because of the design. But energy efficiency also depends on other factors like compressor design, condenser design, etc. Long term or durability depends on how well a model is engineered and not on energy efficiency. And brand value is the best to determine the longevity or durability of a model. As far as brand value is concerned, both Haier and Samsung are quite good. Samsung is a more popular brand just because it is bigger and has lot more appliances to offer. But I don’t think Haier has any great disadvantage. Amongst the two models I think the Haier one will be better for you.

  • Shaheen Farooqui

    I have purchased an LG refrigerator model number GL318PNG4 double door.
    I have observed frost and moisture formation in vegetable crisper.
    What could be the possible reason and please suggest a remedy.

    • Bijli Bachao Team

      Hi Shaheen,

      Is the temperature in the refrigerator section too low? Vegetables needs good moisture to keep them fresh so manufacturers provide moisture control on vegetable crisper. Frost can happen only when the temperature in the crisper is too low.

  • rachit kr singh

    In my village no electricity supply so i already have 300 watt solar pv fixed with 150 Ah tubular battery with 600va luminous lectric inverter fixed, now my question is can i run small fridge of 80Liters OR 47 Liters made of electrolux (Regular fridge)along with 3nos of 15 watt cfl one lcd tv 32 inch and one 200 watt cooller,if no how much more kva of inverter is needed or how much pv panel to be extend with how much AH of battery
    iam with tight budget so looking for cheap power saving fridge with in 10 thousand which simply cools water or some ice..can you suggest how much power dose consume such 80 liter or 47 liter fridge bcoz no shopkeeper able to tell me.
    (Electrolux EC060PSH 47 L Single Door Refrigerator)
    (Electrolux EC090P 80 L Single Door Refrigerator)

    • Bijli Bachao Team

      Hi Rachit,

      Small refrigerators are not very energy efficient. In fact if you look at power consumption of a 45 or 80 lts refrigerator, you will find it similar to that of 190 lts refrigerator. And to run such a compressor motor, 600VA inverter will not be sufficient. You would need about 2-2.5 KVA inverter to run a fridge.

  • Binu

    According to you an inverter refrigerators compressor never switches off, I have a LG inverter refrigerator GL-A282SPZL and I noticed that its compressor does switch off and freezer fan also off that time.What is the reason?. In many inverter ac adds claims power saving up to 65%, but doesn’t mention how much saving compared to 5star rated AC’s.What is the actual powe. saving comared to 5star rated AC.

    Waiting for your reply

    • Bijli Bachao Team

      Hi Binu,

      Is compressor switching on and off frequently for your fridge? If yes then it is a problem because it should not. It can run at a lower speed but it should not switch off. In an inverter AC it switches off only when you set the temperature to 28 and even the outdoor temperature is 28 (which is when there is no need of cooling to be done). But in general refrigerator needs to be much cooler. So it should not switch off in refrigerator and you should call up LG and ask them to check. Is the cooling proper when the compressor is off?

      As for the AC ads, savings are highly dependent on the situation in which AC is working. A lot depends on EER of the ACs being compared as well. As per research an inverter tech AC (in an ideal condition) can save 20% more than a fixed speed AC of the same nominal EER (Energy Efficiency Ratio). BEE star ratings are a range of EERs. BEE 5 star rating is given to AC with EER more than 3.5 (some BEE 5 star rated fixed speed ACs even have EER of 3.9). BEE 4 star is given to those between 3.3 and 3.5. BEE 3 star to those between 3.1 and 3.3 and so on.. Now suppose you see an inverter tech AC with EER of 2.9 then to have an objective comparison you just divide the number by 0.8 (to have 20% more efficiency) and it comes out to be 3.6 (2.9/0.8) …. in that case it will be better if you go for a BEE 5 star rated AC of EER 3.9. But if you have an inverter tech AC of EER 3.5 and BEE 5 star rated AC of EER 3.5 then inverter AC will save 20% more. The ads compare an inverter AC of higher efficiency with fixed speed AC of BEE 2 or 1 star and claim 65%. Also most people who have an existing AC and trying to replace will have old AC which would not be rated or at best have efficiency comparing to BEE 1 star (as the efficiency has improved significantly over the years), and in such case it can easily save 65% over your old ACs.

    • Binu

      Hi, Thank you for your reply.Since you have said it can be problem of refrigerator, I desided to monitor it for few hours and these are my findings.
      Freezer temperature setting @no.3 position and refrigerator @ no.7.
      Compressor off =10 min
      Compressor on =35 min
      off=13 min
      On=30 min
      Off=15 min
      On=02 min
      Off=33 min
      On=14 min
      Off=22 min

      All these times refrigerator never opened, and finally i opened
      the refrigerator and check the cooling and found its proper and
      then opened the freezer and poured water into ice tray closed the door
      and checked the compressor run time and found it was on
      continuously on for 1+ hours.So is it problem or normal thing?

    • Bijli Bachao Team

      You must call LG and ask them to check. I do not think compressor should stop. It should slow down and may be you may not hear the sound. But if it is inverter compressor then it should not stop.

  • Dhruv Arya

    I have zeroed in on Panasonic NR-Bw465XS (450 Ltr.) for style and simplicity in tray allocation. This is with inverter technology bottom freezer.
    1) Any reviews on this model.
    2) Any disadvantage of bottom freezer?
    3) And any comparisions with Bosch KGN57AI50I. Which one is a better buy?

    • Bijli Bachao Team

      Here is our response:

      1) We do not have reviews of this model.
      2) Top Freezer are more energy efficient than bottom freezer.
      3) Panasonic NR-Bw465XS with inverter technology will be better than Bosch KGN57AI50I without inverter technology.

  • http:[email protected] KS DILIP NAGESHWAR

    But why it is called “inverter technology”is the refrigerator consuming power from AC after converting from DC FROM BATTERY

    • Bijli Bachao Team

      It is called inverter technology because it has a brushless (variable frequency) motor that has a rectifier that converter incoming AC to DC and then an inverter that converter DC to AC of desired frequency (which drives the frequency or speed of the motor).

  • Sunil Dhawan

    Which 3 door fridge brand of 450-500L would be the best choice please?

    • Bijli Bachao Team

      Hitachi or Panasonic with inverter technology compressor would be great.

  • Sahasra


    We’re planning to buy a refrigerator around 360 Litres capacity.Can you please suggest which among LG 360 L(GL-D402RLJM ) and Samsung Digital Inverter 345L(36JSRZESP) would be best buy.Also among LG 360 L models-Is there any difference between GL-D402RLJM And GL-402JHSL,Which will be better among these two LG models.

    Thanks in advance

    • Bijli Bachao Team

      Hi Sahasra,

      LG and Samsung are quite comparable brands and the two models that you have listed are both BEE 4 star rated. If you are a vegetarian then Samsung Smart converter fridge would be a delight for you as it will provide you lot more space to store veggies. LG GL-D402JHSL is not much different from GL-D402RLJM. It just has additional SMART Connect feature that makes it easier for it to work on inverter during power cuts. The choice will depend on what amongst all these features is important for you.

  • Saksham

    I am thinking to buy LG GL-D322JGFL. Is it a good choice?

    • Bijli Bachao Team

      It is a BEE 4 star rated refrigerator with inverter technology. It certainly is a good choice.

    • Saksham

      I bought it today but it’s been almost 5 hours of it after installed,the outer body is hot when touched ,not warm but hot.Why is it so?Is there some fault?

    • Bijli Bachao Team

      A hot refrigerator means it is loosing electricity somewhere. It certainly looks like a fault and you must call up the company to check it.

    Are voltage stabilizers required for Inverter refrigerator as they work by fluctuating voltage for various speeds…Correct me if I an wrong

    • Bijli Bachao Team

      Cannot be generalized, but many brands these days have refrigerator models that have a big working voltage range (typically 100-290 V). Which means that the refrigerator can work between 100-290V. In that case you need not buy a stabilizer for it.

      Inverter technology is not available in direct cool single door refrigerators.

  • carmela pascual

    Which is much better, a refrigerator with an adaptive defrost system or with the inverter technology? What is the difference between the two techology?

    • Bijli Bachao Team

      The two are very different. Adaptive Defrost is a technology for evaporator while Inverter Technology is a technology for compressor. Adaptive Defrost times the defrost cycle and controls the defrosting (ice removal) system. While Inverter Technology is a compressor technology which varies the refrigerant flow based on heat load.

  • Uday

    Hi Abhishek,

    I thought inverter range is beyond star ratings. How come inverter fridges have star ratings as well? I don’t see the same thing applied to Inverter ACs. I haven’t been able to find anything on this topic online. Can you please explain? Also, none of the e-tailers seem to have any 5 star inverter range fridges.

    Can you also suggest a couple of inverter fridges in the 300-400 liter range? I don’t mind if it’s little costly upfront as I know the small difference in cost will save big in running expenses.


    • Abhishek Jain

      Hi Uday,

      In case of air conditioners the star rating is provided on the value of Energy Efficiency Ratio (output watts/input watts), for inverter ACs this value is not constant and thus comparing ACs (inverter and non inverter) on EER values is not possible and thus inverter ACs are not provided star rating. However in case of refrigerators, the star rating is provided on annual electricity consumption. And it is easy to measure annual electricity consumption for both inverter and non inverter refrigerator. And thus inverter tech refrigerators have BEE star ratings.

      Now there are very few (about 6-7) refrigerators that are BEE 5 star rated. In 2014 BEE revised their star ratings and made them more stringent. So the old BEE 5 star rated refrigerators moved to BEE 3 star. You can look at these refrigerators:

      BEE 5 star rated refrigerators:

      LG GL-D322RPJZ 310 lts
      LG GL-D322RSJZ 310 lts

    i am planning to buy whirlpool 240 ltr. FP 263D PROTON ROY FIN (N) Refrigerator with vegetable drawer option available in this model. Is it advisable to buy this product? How good the refrigerator performance is in regard to power consumption and cooling technology? please suggest. Budget is between 25k and my requirement is 240 to 260ltr fridge.

    • Abhishek Jain

      Hi Sudipto,

      This Whirlpool model is a 3 door model and BEE has not rated 3 door models yet, so I cannot comment on it’s power consumption. Whirlpool as a brand typically has good BEE 3 and 4 star models, so I would assume that this specific model would not have bad compressor to consume a lot of electricity. But technical data for the same is not available. Most whirlpool models have sixth sense technology which is good for maintaining ideal temperature for keeping food fresh. However in my opinion Inverter Technology compressor is better in saving electricity along with maintaining the right temperature. Are you looking for 3 door models only?

    Dear Abhishek, please tell me which side by side refrigerator with linear inverter compressor is better in the market today,, the various options do confuse,,
    i am looking above 600litre capacity

    • Abhishek Jain

      Hi Awdesh,

      Liner Inverter is LG’s technology. All others have regular inverter compressor. If you are looking for regular inverter compressor refrigerator in side by side models, I would suggest that you may check Hitachi and Panasonic refrigerators.

    • awdhesh

      Thanks Abhishek,,,also let me know which would the best linear or regular, in terms of performance and economy,,thanks once again

    • Abhishek Jain

      Technically Linear inverter AC would be better in saving electricity than regular. However there are multiple factors that impact energy efficiency, compressor being one of them and the most important.

    • Baha

      unfortunately, LG is able to work and adjust in two different temperatures with leaner motor, meanwhile other brands are having piston inverter motors as i mentioned wz 6 speed, like Siemens, Samsung e.t.c. When the temperature changes the Ref. adjust its motor working process. So, LG is able to work in Summer and Winter perfectly, and the same time Siemens or Samsung are able to work in all seasons and plus additionally 2 more temperatures, well, you have to make right choice.

    • Baha

      Avdhesh, LG has 2 speed Inverter motor, which is lenear, Samsung has 6 speed Inverter motor.

    Hi Abhishek,

    Which is best digital inverter technology and BEE 5 start rating refrigerator available in 200-260L range? Can you please list some models here?

    • Abhishek Jain

      Hi Parag,

      You can look at these refrigerators. Some of the models where price is mentioned as NA are latest models as per BEE list. I am not sure if these brands have these models in market or not.

    • Parag

      Hi Abhishek,

      Thanks for the list. Two models of LG – GL-P292RPJL and GL-D292RPJL – both lists feature which maintains optimum cooling inside the refrigerator for up to 10 hrs*, even during power cuts. The GL-P292RPJL model names this feature as Power Cut Evercool while GL-D292RPJL model names this feature as Durachill. Are both function same? Is there any difference in them? Because GL-P292RPJL is costly than GL-D292RPJL. So why is the difference in price? I am just assuming that it could be because GL-P292RPJL has convertible box which other doesn’t.

      Additionally, considering the electricity consumption (unit per year), LG’s GL-D292RSJZ seems to best among all of the above. It has got 5-start BEE rating this category and the only model which has 5-star rating. The approval date is also Aug-2014, so the latest (checked on BEE website). However, it is not listed on LG’s website and when I called-up LG customer care they said they don’t have any information on this model. Should I wait for this model to come in the market as it seems to best among all on power consumption (just 190 units)? How much Rs. can be saved towards electricity bill if I go for this 5-star model than any other 4-star model with 238 units electricity consumption? Do you have any info on this model?


    • Abhishek Jain

      Hi Parag,

      Power Cut Ever cool is for the whole refrigerator whereas durachill is only for the freezer and that is why the cost difference. The difference of 48 units at Rs 5 per unit will cost Rs 240 in a year. If you are in Mumbai where the price of electricity is about Rs 10 then it will be Rs 480 in a year. But please note that depending on your usage the actual consumption of the refrigerator may be about 30% higher than the rated units (as the numbers by BEE are in test conditions). So 48 unit difference may end up as difference of 48*1.3=62 units.

    • Parag

      Thanks again Abhishek.

      So should I wait for this (BEE 5-star) model? Do you have any update on this model – when can it be available?

    • Abhishek Jain

      It is quite some time since this model exists in BEE list (so manufacturer registered it), but is not available in market. I think for now you can go for any of the BEE 4 star rated models.

  • Siddharth

    Hi Everyone!
    Well, this is Siddharth from Kolkata.
    I was using my whirlpool refrigerator (GNF220x) for more than 15-16 years and it did not have any problem. My monthly bill used to be unusually high. Suddenly after years I though to find out why, and then found out that the old refrigerator is the culprit and it takes almost (7amps at startup) and steady current of around 1.2 Amps at 230 Volts, making it a gadget of something like 276 watts, and I found out that it worked for around 23 hours per day, making me pay for 2317 kWh (ie; 2317 Units per year, Yes you read it right! It was of a conventional compressor and with that age I thought it was of no use to get it serviced as I really wanted a CHANGE, this change means change in the power consumption). Like, many of you even I had gone through a dilemma to choose the correct refrigerator as per my need, I made up my mind to go for only inverter based digital compressor refrigerator, somehow I liked the Samsung refrigerator more. Samsung RT29HARZERY, I just went for it.

    BEE 3star rated Samsung RT29HARZERY inverter, it claims to consume 305 units per year as per standard BEE conditions.
    I knew, or rather had belief that it might consume even 30% more electricity under normal usage, and made up my mind that, its still fine even if consumes 400 units per year as my earlier frost-free one was consuming more than 2300 units per year.

    I tested the current consumption of my new refrigerator, found it to be around 0.5 amps at around 230 volts.
    I was sure that it would decrease within some time or rather few days.

    After 5-6 days of usage, I tested several times and found almost the result consistent.
    Today also I checked and found it to be 0.156 Amps at 228.6 Volts.
    Indicating it a load of just 35.6616 watts!!
    that means when used for 24×7, 365 days, it would consume just 312.39 units.

    I know this result can vary with seasons, but it is going to be more or less consistent.

    I’m stunned to see this result.

    BEE Claims 305 units per year for this Samsung RT29HARZERY
    My test indicated that it would consume 312.39~ 312 units!!
    Percentange of accuracy is 97.75%!!! (almost 98% accurate result)

    P.S.: I’m really thankful to Abhishek jain for all the suggestions.
    All the forums are very informative.
    Keep it up Bijlibachao!


  • Vikram kr singh

    I want buy new fridge for my mother which are living in village three to four hour elect City daily come so can I use fridge on inverter how much volt inverter to use also 400 volt solar panel use 850 volt inverter to charging use . Please tell me how much volt inverter to fridge per litre thanks

    • Abhishek Jain

      Hello Vikram,

      Typically refrigerators motors are rated at 300-400 watts or 550 VA in steady state. However regular motors need much higher startup current and thus it is typically recommended to get a 2 kVA inverter for a regular refrigerator. But with inverter technology refrigerator the startup current required is less than the steady state current, so if it is rated at 400 watts, it would just need about 450 VA inverter to work. So if you have a 850 VA inverter then I would suggest that you go for a refrigerator with inverter technology. The smallest size inverter technology refrigerator available in market would be a 253 lts double door refrigerator and the brands that would have such models are Samsung and LG. A BEE 3 star rated Samsung model would cost about Rs 20000 at least. And BEE 4 star would go up to Rs 26000. It will not only work on lower capacity inverter, it will also consume less electricity which means your battery will run longer per charge. Additionally if you go for a LG model with Power Cut Evercool technology, it will keep the food in refrigerator cool for 9 hours during power cuts (without using electricity). But it will be a bit more costlier (say about 27000-28000). So the options are either to go for larger inverter (a 2 kVA at least) or go for inverter tech AC that would use lesser resources. There are costs associated with either option.

    I have one Leonard refrigerator which has slow speed compressor and it is working fine. Is there any fridge today having slow speed compressor?

    • Abhishek Jain

      Hello Mr Kumar,

      Sorry, I am not aware of any slow speed compressors in the market.

  • Gopal

    Dear Abhisek, Thank you for your reply. Sorry to bother you again. Is Samsung RT50HS809SL better than a Panasonic fridge NR-BY552XS
    in terms of energy consumption.

    • Abhishek Jain

      Hi Gopal,

      Panasonic NR-BY552XS is not rated on BEE star rating as it is a bottom freezer model. I cannot comment on that. Samsung RT50HS809SL is a safe buy.

  • Gopal

    Dear Abhisek, I plan to buy Samsung RT50HS809SL. Please suggest if this is a good buy in near 500lt range. Thank you. Gopal

    • Abhishek Jain

      It is a good one with smart freezer (convertible freezer). You can go for it.

  • shamshad parveen

    hi abhishek, im thinking of purchasing a DIC refrigerator of 300-400lts volume with bottom freezer.pls suggest me a good brand.im stuck between samsung&panasonic.

    • Abhishek Jain

      I would suggest that you go for Panasonic DIC if you are thinking of going for bottom freezer. Panasonic model NR-BW415XS with econavi and inverter tech would be the best. Else you can also look at Panasonic model NR-BW415VN.

  • Jim

    I have heard that while the Inverter compressor technology is better, its energy savings is offset by the fact that it performs an auto defrost on an 8hour per day basis. In terms of total energy efficiency, how are they then compared to Electrolux ETE3500SE and Whirlpool Neo iChill WIE120USS, both have conventional compressors but claims to have the Adaptive Defrost technology which only turns on defrost on a per need basis.

    Which would be the best freezer option, one that has the freezer in the Top section or the models that have the drawer options in the bottom part of the refrigerator?



  • Nitin

    Hello Pankaj,
    Which would be the most energy efficient side by side refrigerator with storage capacity of 550~600 ltrs, that runs on inverter technology and available in the Indian market presently. If you also gave me the price, it would be of great help. Thanks.

    • Abhishek Jain

      Hi Nitin,

      We do not have data on power consumption of side by side refrigerator as it is not made available in public domain by most manufacturers. However you can look at Hitachi, Panasonic, LG and Samsung brands.

  • Dipak

    I am planning to buy Refrigerator for home.

    Which one is better?

    LG GL-E302RPTL or Whirlpool Neo IC 305 ?

    • Abhishek Jain

      LG GL-E302RPTL is BEE 4 star rated refrigerator with inverter technology compressor. Whirlpool NEO IC 305 Royal is BEE 4 star but Deluxe is BEE 3 star but both do not have inverter technology. Inverter Technology is better in general.

  • SyedAleem


    I wanted to know what’s the difference between Smart Invertor technology (the 1 we have in LG) and the Digital Inverter technology (the 1 we have in Samsung) ?? Which is better interns of performance and durability. I likes LG product due to its build quality compared to Samsung. Please suggest on this ???

    • Abhishek Jain

      Smart Inverter and Digital Inverter are the same. The only type that is different is Linear Inverter which is there in LG. Inverter Technology is a SMART technology because it auto adjusts the compressor speed based on the load. It uses digital components to do the same. However Linear Inverter is a technology where motion of the compressor is linear which minimizes the energy loss in motion of the compressor. Along with that it auto adjusts its speed based on the load.

    • Renz Alfred Villegas

      SMART INVERTER is the brand term for Samsung Inverter ACs. DIGITAL INVERTER is the term used for Samsung Inverter Refrigerators. As for LG, LINEAR INVERTER is the term used for their technology. In fact, Linear Inverter should not be used since LINEAR COMPRESSOR and INVERTER COMPRESSOR are different. Linear compressor can also save a lot of energy compared to AC COMPRESSORS but INVERTER COMPRESSOR saves more than LINEAR to prove, only LG uses LINEAR technology. As for build quality, I might not agree to that, I work for an appliance store and the number customer complain is LG compressors are noisy and not that energy efficient (not to give samsung all the credit but that’s a fact)

    • Abhishek Jain

      Hello Mr Kuchhal,

      In 340-400 lts range it is better to go for double door frost free models. Single doors are good up to 250 lts range. Also in this range it is better to go for refrigerator with inverter technology (most BEE 4 and 5 star refrigerators in this range are inverter technology). LG and Samsung will give 10 years warranty on the compressor as well. Inverter tech will also generate much lesser noise and will give maximum freshness. You can look at these models that may fit your needs:

  • Pankaj

    Hi Abhishek

    I want to buy a fridge around 550-600 litre which has good build quality and also easy to maintain via good after sales services. I was thinking b/w Hitachi . Sharp & Samsung. I heard Hitachi after sales is pathetic and not getting complete info on Sharp’s After sales service. SO its making me reort to Samsung side by side model rs21hstpn1. Can you comment on whether it is a good choice or not and if not would like to know your recommendations.


    • Abhishek Jain

      Hello Pankaj,

      If you are looking for star rated double door refrigerators then you can look at these:

      LG GR-B772GSPH
      Samsung RT56H6679SL

      both of these are BEE 3 star rated models. Hitachi also has some models in BEE list that are 4 star rated, but these models are not available in market. If you are looking for side-by-side models, then all I would say is look for models with inverter technology compressor. Sharp is a good brand with good value for money, but their service is patchy at places. However it would be good if you are in a big city (heard good feedback in Mumbai). The model you mentioned does not have inverter tech compressor. There are couple of benefits of inverter tech: 1) It save about 30-40% on electricity consumption 2) It gives consistent cooling so food remains fresh.

    • Pankaj

      Thanks Abhishek, I am in Delhi so am assuming Sharp service will be reasonable. Also one thing, usually the side shelves of refrigerators get cracked easily. Will buying Sharp product at least lower the possibility of cracking as I presume they have better quality than samsung/LG etc. Also are these parts available just in case it breaks.

    • Abhishek Jain

      Hi Pankaj,

      I am not sure about that.

  • Kristhy

    Thanks a lot !! Your explanation is very helpful .
    Kindly suggest me any good model of 250 to 300 litres Frost Free with cooling gel technology
    does cooling gel technology really keeps it cool for at least 2 to 3 hours
    The fridge dealer in my place is of the opinion that direct cool keeps stuff cool for at least 3 to 4 hours because of the ice formed inside compared to frost free. I want your expert opinion
    Thanks a lot once again

    • Abhishek Jain

      You can look at:

      LG GL-E302RPTL
      LG GL-P302RPJL
      LG GL-D292RPJL
      LG GL-E292RPTL
      LG GL-P292RPJL
      Whirlpool Neo IC 305
      Whirlpool Neo IC 275 (has deep freezer with chilling gel)

      These can keep food cool for 9-10 hours in power cuts. And this is different from what the direct cool refrigerator does. Although if ice is formed, even direct cool can keep food cool for some time.

  • Kristhy

    How long the frost free refrigerator will keep cool in case of power failure ?

    • Abhishek Jain

      As I said it all depends on technology. Some Frost Free refrigerators also have cooling gel technology that can keep the refrigerator cool for 9 hours during power cuts.

  • Kristhy

    Hi Abhishek
    I am planning to buy a refrigerator, can you suggest me few options ? my criteria are below
    1. Volume less than 300 litres
    2. There is a not much electricity problem in my area, so looking for a product which is good in 1/2 to 1 hours long power cut.
    3. Cost around 15 thousand
    4. Exclusively to keep fish, meat& vegetables
    5. You Can suggest any good brand .. I am not particular to this.
    6. How long the frost free refrigerator will keep cool in the power cut
    7.Which one is good direct cool or frost free from cooling point in area where 1 to 1&half hours power cut
    8.Difference between direct cool & frost free refrigerator

    • Abhishek Jain

      Hi Kristhy,

      It will be difficult to get a 300 lts fridge at around 15 thousand. You can get refrigerators of around 200 lts in that budget. Brands like LG and Samsung have technologies to store cooling in gel which can be used during power cuts. LG claims that it’s power cut evercool technology can keep the refrigerator cool for 9 hours during power cuts.

      Also it will be difficult to get frost free refrigerator in your budget. Direct Cool refrigerators are single door refrigerators that need manual defrosting. Which means ice accumulates around the freezer and you need to switch it off periodically to remove the ice. Frost free refrigerators do this automatically and you need not switch off the refrigerator.


    Hello Abhishek,

    I want to buy low coast refrigerator around 15k of 190 Ltr. But I am confused in brand. My choices are LG and Samsung.
    I tried searching over internet but could not come to decision that which one is better brand..?
    Please guide me which refrigerator should I purchase..? LG or Samsung..?

    • Abhishek Jain

      Although they are almost equally energy efficient. Samsung provides slightly more volume with slightly less energy consumption. So you can go for Samsung.

  • Vandana

    Hi Abhishek we plan to buy a 550/ 600 l refrigerator with a higher fridge is to freezer ratio. Also there is a lot of confusion in the market regarding an inverter tech. compressor. As per my understanding, truly invertor compressor refrigerators or ac s should not have a star rating. How come most of the brands are advertising inverter compressor refrigerators, but also have a star rating alongside? To me, it appears like an advertising gimmick rather than anything else. The only refrigerators with invertor tech compressors are Hitachi or Panasonic, I think. Could u pl clarify this for me and also suggest a good model for my needs?

    • Abhishek Jain

      Hi Vandana,

      There is no star rating for Inverter Tech ACs, but there is star rating for double door inverter tech refrigerators. Side-by-side, Multi door and bottom freezer refrigerators are not rated on BEE star rating yet. Hitachi and Panasonic have inverter technology refrigerators in bigger size (in the size range that you are looking for), however most of them are side-by-side and multi door that are not rated on BEE star rating. In fact Hitachi also has 6 double door models registered as BEE 4 star rated refrigerators, but they are not available in market. The only double door refrigerators (of the size you need), that are registered on BEE star rating are these 3 that are BEE 3 star rated:

      LG GR-B772GSPH
      SAMSUNG RT56H6679SL
      SAMSUNG RT54H6679SL

  • sameer

    Hi Abhishek,, I am planning to but a 450-500 ltrs double door refrigerator. I was thinking iof buying Bosch. Any feedback on bosch?. I live in mumbai so is service an issue? And what are the best invertor tech refrigerator in this segment?

    Also 2nd question is, we need smaller freezer so is there a 80:20 ratio in some models . Mostly i found 70:30.

    Pls guide.

    • Abhishek Jain

      Hello Mr Sameer,

      If you need less of freezer space then you should look at convertible freezer models from Samsung having digital inverter compressor (e.g. RT45H5809SL). In this you can use the freezer space as refrigerator when needed. This models is BEE 3 star rated. Bosch models are BEE 2 star rated and do not have inverter tech compressor.

  • Abby

    Hi Abhishek,
    This is very helpful and explained it in a way that non-technical people will understand. Thank you very much. Can you help decide between LG’s Linear Inverter and Samsung’s Digital Inverter. Which is better in terms of energy efficiency pls? Thanks!

  • Ajayk

    Hi Abhishek,

    Can you please suggest which is the best one out of the below mentioned.

    1: LG GL-M522GSHM(SV) Frost Free

    2: Samsung RT49H5679SL

    Consider all the factors energy saving, after sales service and long term working product.

    • Abhishek Jain

      Hello Mr Ajay,

      LG GL-M522GSHM is a BEE 4 star rated refrigerator with rated electricity consumption of 290 units a year. Samsung RT49H5679SL is a BEE 3 star rated refrigerator with rated electricity consumption of 360 units a year. Both are inverter technology refrigerators, so good products. The price difference between the two is quite less. The LG model will save more electricity for you because the rated difference is 70 units, which will turn out to be a difference of about 100 units on use (because usage units are 30-40% higher than rates units in refrigerators). So depending on your rate of electricity you can work out the energy savings for 100 units a year.

      Now from after sales service perspective both LG and Samsung have similar standings. Depending on location one brand may be better that the other, but on the whole, both are equally good. So I think LG will be a better option for you.

  • chhaya

    Hi Abhishek

    We are planning to buy 300 – 400 litre capacity refrigerator. I have heard that LG and Samsung will b best. Would like to know from you that which brand should we go for so that for next many years we don’t have to think of changing it.


    • Abhishek Jain

      Hi Chhaya,

      Both LG and Samsung have inverter tech refrigerators in this range, which is the technology to look for. Most of Samsung models are BEE 3 star as per 2014 ratings. LG has 5 and 4 star rated refrigerators as well.

  • Vishnugopal VG

    What is the difference between lg inverter linear compressor and the newly launched smart inverter?

    • Abhishek Jain

      Linear inverter is LG’s technology where the movement of compressor is linear instead of reciprocating. LG claims that it is more energy efficient that regular inverter compressor. And all inverter compressors are called Smart Inverter because they adjust according to the need of the system.

    • Yogesh

      How can Samsung digital inverter has star rating

    • Abhishek Jain

      No inverter ACs have star rating yet.

      Hi Bhargav,

      Just looking at BEE data I can see Hitachi having lot more BEE 4 star rating models whereas Haier is mostly 2 and 1 star and some 3 star rated models. I cannot give you data more objective than this to give a comparison.

  • asis patnaik

    Hi…plz suggest a Best energy saving fridge 340 to 360 litres? And how come the same model Samsung fridge RT36FDJFASL is 5 star rated in 2013 & 3 star rated in 2014? My cousin has brought the above mentioned 2013 model this year, so is that means his fridge is 3 star efficient only. Kindly clarify please.

    • Abhishek Jain

      Try LG GL-D402RSHM or GL-D402RPHM or GL-D402RLJM. The BEE star rating standards have been revised in 2014, so some of the refrigerators have come down in ratings. So yes the refrigerator you mentioned is BEE 3 star.

      Hope this helps.

    Hi Abhishek,

    I have a doubt regarding inverter technology.. if an inverter ac cools the room to desired temprature while working at its minimum capacity and if temp drops further then will its compressor turn off for some time as a normal ac?? actually i see many time the fan of my 2ton Mitsubishi ac outdoor unit turns off and then on even the daikin 1,5ton ac in other room does the same. If this happens does it have any bad effect on the life of compressor???

    • Abhishek Jain

      Hi Jagat,

      Inverter ACs are designed in such a way that the compressor never turns off. Firstly let me tell you that even if the thermostat senses that the optimum temperature has reached, the flow of heat into the room does not stop. If your room is cooler than the outside temperature, the heat will flow into the room continuously. It does not stop even for a moment. What the inverter AC does is that it optimizes the speed of the compressor in such a way that the rate of heat it takes out from the room is same as the rate of heat coming into the room. So initially it does run at a higher speed (to reduce the temperature), but it stabilizes at a consistent speed once the rate at which it is taking out heat is equal to rate at which heat is coming in.

      Thus it is also said that inverter ac is much more consistent in maintaining temperature, as the temperature will never go down from what you have set on thermostat. Whereas in a fixed speed AC the temperature may go down about a degree centigrade more when it stops.

      Hope this helps.

    Hello Abhishek,

    Thanks for your valuable and precise inputs about the inverter technology of refrigerators.

    Which company provides the best Split ACs with inverter technology in 1.5 ton ?

    Thanks in advance.

    Gurpreet Singh Sidhu

    • Abhishek Jain

      Hello Mr Singh,

      Personally from a technology point of view we have a preference for Japanese brands, but truly every brand has its own pros and cons. But all brands offer inverter technology AC in 1.5 ton.


    • Gurpreet Singh

      Hello Abhishek,

      Prior to buy split Inverter AC, I want to know what would be the Tonnage of the Air Conditioner for following:-

      *Area (sq. ft) ? 130
      *Height of the room. ? 10 ft
      *Usage of the room ? Bedroom
      *Maximum No. of Persons in the room at any given point of time. ? 3
      *There is no wall which that is directly exposed to sunlight
      *Even roof is not exposed to sunlight

      Gurpreet Singh

    • Abhishek Jain

      Hello Mr Singh,

      The best thing about inverter tech is that it can auto adjust to your need. So even if you go for a 1.5 ton inverter tech AC and your room needs only 1 ton, then it will auto adjust its tonnage. However to tell you the right tonnage I need to know the city where you are based.


    • Gurpreet Singh

      I live in NOIDA

    • Abhishek Jain

      Hello Mr Singh,

      A 1 ton inverter tech AC would be enough for your room. Below are some brands/prices that we got from the internet:

      LG BS-Q126B8R8 Max tonnage 1.15 ton, Price about Rs 39,999 (on compareindia)
      LG BS-Q126B8A4 Max tonnage 1.15 ton, Price about Rs 42,990 (on reliance digital)
      Sharp AH-XP13LV Max tonnage 1.2 ton, Price about Rs 31,700 (on compareindia)
      Carrier Kurve Inverter AC, Price about Rs 35,488 (on compareindia) ? Carrier also has a superia inverter range for which price is not known to us.
      Daikin 1 ton Inverter FTKE35, Price about Rs 35000 (on snapdeal)
      Mitsubishi has MSYGE13VA (price of which is not known to us).
      Voltas Delux (DC Inverter) 12V DX 1.0 Ton, Price about Rs 39,990 (on Naaptol)

      Hope this helps.

    why it is the difference between Inverter compressor and linear inverter compressor

    • Abhishek Jain

      Hi Vijay,

      Inverter Technology adjusts speed of compressor motor depending on the heat load in the refrigerator. A regular compressor motor has a rotational movement. LG has a proprietary technology which it calls linear compressor where the movements are linear instead of rotational. LG claims that it saves electricity. Now they have combined the inverter technology with their linear compressor technology and call it linear inverter compressor. So logically thinking linear inverter compressor should have benefits over regular compressor, but the effect needs to be studied and we at Bijli Bachao have not done any research on that yet.

      Hope this helps.


  • bhavesh soni

    Hello Abhishek,

    I love the direction you work in!! congrats.

    can you guide me apart from SAMSUNG what are other economical models available with inverter tech.

    I have heard about this

    Panasonic NR-B295STW4.

    I am looking aroung 260-300 litre..
    Again thanks!!

    • Abhishek Jain

      Hi Bhavesh,

      There are several brands that make inverter tech refrigerators. In fact these days almost all brands have a few models that are inverter tech. But not all brands have models in all sizes. Most brands including panasonic have inverter tech in model of sizes 400 lts and above. I checked the model you mentioned online and it does not have inverter technology. Samsung is the only brand that has inverter tech in smaller size refrigerators. Haier has few that are less than 400 lts but still they are bigger than your requirement. You may also look at BEE 5 star rated refrigerators of the size you need (although inverter tech may save 20% or more electricity as compared to regular ones). Please note a 5 star refrigerator of 260-300 lts would consume about 1.5-1.75 units a day.

      Hope this helps.


    • bhavesh soni

      Thanks Abhishek!!

      Precisely samsung digital inverter does the job neatly. Also as mentioned in reference PDF http://www.panasonic.com/industrial/includes/pdf/invertercompressors-improvingefficiency.pdf

      These refrigerators do work efficiently.

    • Abhishek Jain

      Inverter tech uses variable speed motors that help it adjust its speed according to the system requirement. Regular compressors have fixed speed motors and are mostly sized for higher capacity which is not always the case as seasons change and heat in the environment varies. Inverter tech is elastic and thus more efficient.

  • sasikumar

    it very good, thanks this is same method to air conditioner compressor

    • Abhishek Jain

      That is right, the method is same for air conditioners as well. And because of their capability to vary capacity, they save energy. I am glad that you found the information useful.


  • Shwetha

    nice info…so, if is better I opt for an inverter based refrigerator, if I want to power it using solar energy…since the compressor does not turn ON or OFF but only varies the speed of operation, the surge is usually very low or non existent..am I right?

    • Abhishek Jain

      Hi Shwetha,

      You can use PV system with any kind of refrigerator (inverter tech or regular). Just that the sizing of the system must match the maximum power requirement of the refrigerator. You will need a PV module, charge controller, batteries and DC/AC inverter to connect to the refrigerator.


    • Shwetha

      Thanks Abhishek for the info.

      Dear Mr. Abhishek Jain,

      I am planning to buy the Hitachi R-WB480PND2. Please let me have your comments on this. Please let me know any alternative fridge which you think is better than this. What could be the annual electricity consumption for this fridge.


    • Abhishek Jain

      Hello Mr Kasinath,

      If you are looking for multi door model then Hitachi R-WB480PND2 is a good model. It has inverter technology compressor which will be energy efficient (electricity saving) as well as will keep the food fresh for long. You may get some models in LG/Samsung with similar technology and multi door. But this is a good one as well. It should have electricity consumption of about 300-330 units a year.
