Electricity Saving Tips For Homes And Offices

Solar Conversion Kit: A better way to use existing inverter battery system with Solar PV

By on April 22, 2016

We at ‘Bijli Bachao’ have been getting a lot of queries from our readers, on how to apply the solar inverter technology in the houses, do we need to completely replace the existing inverters, what all modifications are required, and is it possible to apply the solar panel to the regular inverter?, etc. are some of the pertinent queries, which we keep getting on this subject. Therefore we have decided to dedicate one article on this topic, whose application will not only lead to a continuous supply of ‘green’ power but will also lead to a significant savings to the electricity bills.


What is Solar Conversion Kit?

We all know that solar cells, also called photovoltaic (PV), convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is also called as the PV effect. With the concept of the solar conversion kit, any inverter or battery can now be converted into a solar inverter. Solar conversion kit is an additional device or a solar panel which could be connected to our existing home inverters, thus converting the system into a hybrid form. By converting the normal inverter into the solar hybrid inverter, one can connect solar panels to it and start using the solar energy available in the day time for the normal daily use.

How Does Solar Conversion Kit Work?

The solar conversion kits introduce mainly two new parts to the existing inverter system; solar PV modules and the solar converter. The solar PV modules are installed on the roof top at a fixed tilt and generally facing south direction of the location. The energy generated will be brought to the solar converter which is located near the inverter and battery bank. When sun rays fall on these solar panels, the power (DC electricity) is generated, which reaches the batteries through solar converter and batteries get charged. However, the solar panels ensure that the right amount of charge reach the battery because with very high power, there are chances that the batteries may get permanently damaged. A solar converter charges the batteries in different stages and gives a controlled amount of charge, so that they not only get fully charged, but are also able to hold the 100% charge.

Now, when the batteries get fully charged, this solar converter protects batteries from overcharging by intelligently disconnecting the solar power. It also safeguards the solar panels by prohibiting the flow of current in reverse direction from batteries to the solar panels during the night time. During the day when solar power is being generated and is fully charging the batteries, solar converter available in the market also has the ability to intelligently disconnect the mains and power the house via inverter using the energy stored in the batteries. These handy solar converters take almost nothing from the main power supply which means that they do not bring any extra burden to the electricity meter – thus one can generate significant savings in their electricity bills.

When batteries are drained these solar converters first tries to get them charged through solar but in absentia of the solar energy such as during the late evening or the night times, the inverter goes on to the mains mode and gets the power from main grid supply. During late evenings or when sun is pertinently not available, solar converter ably detects that and switches the mains on. The inverter charges the battery through main grid supply so one can get non-stop electricity supply even during power cuts at night.

What is in it for me – Price?

It lets one use the free and green energy generated by solar panels to power all its electrical appliances. One can make huge savings on electricity bill and get to charge the batteries even during power cut and of course help save the environment. Moreover, one also does not need to make any additional investments like purchasing a new inverter set-up, etc, one just needs to put a panel to the existing inverter and enjoy the benefit.

In India, Sukam, Exide, Luminous, Microtek, VGuard, Tez, OKAYA, etc. are the leading players in home inverter manufacturing sector. In the solar inverter market, there are Su-Kam’s patented Solarcon panels/devices, and the Luminous Hybrid Solar Inverter, the most popular branded ones; which can convert any ordinary inverter and battery set-up into solar power system. So, not only one can save energy and cut down on its electricity bill, one is also ably protected with uninterrupted, green power, 24X7 times. For normal use the 250 watt battery inverter kit is recommended, but if one wants to install a high capacity solar panels such as 400, 500 or above 500, then there are battery inverter kits such as SolarCon 24  volt (double) available in the market.

These solar panels are priced somewhere between 2500-3500, depending upon the brand. Infact since the price difference between non-branded conversion kit and the branded conversion kit is minimal; one is advised to go for the branded!

Thus, the solar conversion kits certainly provide a better way to use existing inverter battery systems with the Solar PV technology, one just need to apply this cost effective technology.

HI , My household load is around 2500 watts . i have a microtek 5 kva normal inverter set with 8 exide batteries installed. it gives me a wonderful back up in winters but in summers i have to use DG set for an hour or 2 . Now i am planning to extend my load from 2500 to 3500 . so i am considering adding up solar panels
my local dealer told me to install around 5000 watts panels ( rate for monocrystalline panels 32/watts ) and a 96v 30 A charge controller MPPT ( rate 26000 ) .my house is a 5 story building so the total wire length from panels to batteries would be 75 feet ( cant shorten it ,batteries have to be at ground level )
Now i want your help ....is it the right quotation ? any expert suggestions? and 75 feet long wire ? which type of wire should i use ? regular ones or some special ones
and finally will it be an effective system i mean how much will be the losses due to so much wire length ?

20

I think u use 25 mm wire normal .And use mcpt technology with panels. For more details u can call me on my personal no 9919991889

Partha Pratim Panda

I am highly interested about the prospect of Solar Energy for household needs. In our area, the voltage of the grid line is very low. It is always between 100 volt to 150 volt. Moreover, there are frequent load-sheddings. The situations get worsened during the times of storm, lightning, thunder and heavy rain.

In these circumstances, I want to run all the electrical equipments of my house mostly on Solar Energy (and to cut down my Electric Bill too). If not possible, at least, some of them. The maximum load of my house can contain 4/5 LED Lamps, 3/4 Ceiling Fans, a Desktop PC, a Refrigerator and a 1 HP Submersible Pump ( 10 - 15 Minutes a day). I have a 850 watt Inverter with 150 VA Tubular Battery (ST 500). The battery has been running since 2004 and is still giving moderate-good back up

I want to know :-

1. What will be the cost to run all the Equipments on Solar Power (Considering standard consumption).

2. What will be the cost to run all the Equipments Except The Refrigerator and the Pump on Solar Energy (Considering standard consumption).

3. What will be the cost if I wish to run a 1.5 Ton Inverter Tech AC plus all the other equipments on Solar Energy.

4. What will be the cost if I wish to run only the 1.5 ton AC on Solar Energy.

5. If there is any subsidy for the project and how to avail that.

I shall be highly obliged if you kindly provide me with the informations sought above.

Hello Mr Rao,

We have written in detail about sizing of inverters and solar PV on these links:

https://www.bijlibachao.com/solar/sizing-batteries-and-inverters-for-a-solar-pv-system.html

https://www.bijlibachao.com/appliances/choose-right-inverter-ups-for-home-and-maintain-it-right-to-manage-electricity-bills.html

Reading these would give you a good idea on what should be good enough for your house. It will be important to first list out the appliances that you plan to run on solar backup.

34

i decided to have solar panel at home but i have Question about it that if i directly connect it to dc to ac converter and then to mains.... Can it be possible to have Sufficient electricity To run refrigerator And other appliances (like light ,fans ,Air conditioner)???....

35
Abhishek Jain (Mod)

You will need a huge solar panel to run refrigerator or AC. For e.g. an AC may need 10 Amp current at startup (which is roughly 10x230x0.7 = 1610 watts) but just to start the compressor it would need 20 Amp which will increase the wattage to double the amount (roughly 3220 watts). It can be more depending on the power factor of the system. So firstly even if you look at standard wattage requirement of the AC, you would need 1610 W power from solar panel to keep it running in steady state. On top of it you need 3220 W or more to start it. Typically to run a 1.5 ton AC you would need 5 kW solar panel. Similarly to run a refrigerator you would need 3 kW solar panel. If you add many more appliances, it would be close to 10-12 kW.

Hi Team,

Need your advice on installing solar inverter for my house.We are planning to replace our regular 2kv inverter since the batteries are gone dead and due to frequent power cut during summer. We are looking for 2kv solar inverter with 5 to 6 hours backup. The house is located in the village and there is no space constraint and plenty of sunlight available till 4 pm.

Below are the circumstances under which we are expecting the good result of the product

1.Frequent power cut

2.Almost all day low voltage during summer days since water pumps running in the farms .
3. Heavy thunderstorm and lightning during rainy season (Our current inverter is kevin and every monsoon season it gives problem)
4. Max load 2kv.
5. Longer battery life at least 5 years.
6.requires pure sinewave (kevin inverter produces lots of noise and distortion in the electronic gadgets)

Could you please advice on the below,

Complete solar package or buying a regular inverter and installing charge controller and solar panel which one is good? please advice,

Which are the best installers in india currently who provides complete solar package? Can i go for tata solar?

If i buy regular inverter and separate solar charger controller and panel which one you recommend?

What are the benefits of solar batteries ?

Please advice..

37

Hello Mr.Vishwanath, Considering your 2KW load and and back up required you can go for 3KVA 48V Solar inverter, 4*150 AH Solar batteries will give you 3 to 3.5hours of back to your entire load you can reduce the load while running on batteries to increase the back up or increase the batteries to 8 to increase the back up.
To avoid problems during rainy season ensure that the inverter in installed at a place with no moisture and there is proper ventilation.
you can go for a regular inverter with a separate charge controller, or you can go for a solar inverter with inbuilt charge controller, and while selecting a controller or inverter with inbuilt charge controller you have to choose between MPPT or PWM controller. MPPT are little expensive but efficient
Tata Solar panels are good but expensive there are other panels available which are equal from performance standpoint and low in price.
And as for as batteries are concerned go for solar batteries as most of my customers are pretty satisfied with the performance.benefits of solar batteries
Average Life is 7-10 years, compare normal tubular battery where it comes 5-7 years.
comes with 5years warranty
extra backup, Low self discharge

For more info and Solar packages at competitive price you can call 8527070778

Hello Sumith,
Thank you very much for the detailed info, Much appreciated.Considering the above suggestion i think its going to be bit expensive for me.
We have decided to exclude Fridge and washing machine and maximum load would be 1500 watts and in average use it would be below 1000 watts.So can i go for sukam falcon plus 1600va inverter and separate charge controller or is it less expensive if i go for solar PCU which serves my purpose.
Can you please advice which inverter i should choose which has latest technology and good efficiency?Thanks in advance.

39

Inverter should be installed basis maximum load you will run so for 1500 watt you would need 1900 VA inverter. So go for 2KVA inverter and basis your usage you can either reduce or increase the solar modules. From technology standpoint go for MPPT Charge controller

40

Thank you Sumit..I have decided to go for suakm 2KVA/48V solar PCU with MPPT charge controller and 150 AH solar batteries hope i can expect 6 hours back up with 50% load?

Dear Team @B.B
Need your advice , I own a 630sq fet superbuilt-up flat on the 3rd floor of a building in mumbai. Lets say If i am willing to invest in solar energy for this flat , how do I go about it, also since we need batteries in all set ups what is your view on its impact on the environment , I guess a lot of ppl don't use solor energy for flats , but then if its possible , why not? please advice (however i will need ur guidance from start to finish please)

vishal

45

Vishal ji, One of the problem in installing a Solar PV system in a group housing society is the roof right, as roof is common for all members, 2 nd problem can be as you mentioned your flat is on 3rd floor and if your society is a multi storied building then there may be lot of energy losses unless you can have your batteries installed on the roof. If yours is the top floor and you have the roof right then you should not have any problem

46
Abhishek Jain (Mod)

Hi Vishal,

Lot depends on the amount of terrace space that you have and the direction in which you can install the panel. Panels should face south to get maximum sunlight. If you can get that and you have space, then you can certainly install a solar panel. In fact in Mumbai the tariffs are quite high and solar may come viable. But first thing is that you should have space and sunlight from right direction.
