Are you planning to buy a new inverter or upgrade your old one? Whatever maybe the reason, it is very important to understand what is the right inverter for your home. The power requirement at your home can be different from you neighbor’s home. So do not just blindly install the same inverter (in terms of power) in your home. Before buying an inverter for your home do a little homework and understand the basics.
At the end, we’ll also recommend some reliable and secure batteries from sellers that you can trust on Amazon.
First understand your Power Requirement
One of the most important factor that you must know before buying an inverter is your “Power requirement”. In simple words- what all electrical appliances (like fan, tube lights, television, CFL etc.) you want to run at the time of power failure. The power requirement is addition of the power consumed by various electrical equipments.
Suppose you want 3 Fans, 3 Tube lights, 1 CFL & 1 television to operate at the time of power failure. Below is the power consumed by these items:
1 Fan – 70 Watts
1 tube light – 60 watts
1 CFL – 25 watts
1 Television – 120 watts
Therefore your total power requirement is ( 3*70 +3*60 + 25 + 120) = 535 watts
Find the VA rating of the inverter you need
It stands for the Volt ampere rating. It is the voltage and current supplied by the inverter to the equipments. If an inverter operates with 100% efficiency, then the power requirement of the electrical items and power supplied by inverter is same. But we all know that 100% or ideal conditions don’t exist in real. Most inverters have the efficiency range from 60 % to 80%. This efficiency is also called power factor of an inverter and is simply the ratio of power required by the appliances to power supplied by an inverter. Power factor of most inverters ranges from 0.6 to 0.8.
Hence Power supplied (or VA rating of inverter) = Power requirement ( power consumed by equipments in watts) / Power factor( efficiency).
Here average value of power factor or efficiency is considered i.e. 0.7
Power of inverter (VA) = 535/0.7 = 765 VA
In the market 800 VA inverters are available. So an inverter with 800 VA will be the right choice for your home.
Know the battery your inverter needs
Battery is the backbone of an inverter system. The performance and life of an inverter largely depend upon the battery quality. The next big question is “how much back up will an inverter provide?” or for “how many hours it can run all of your equipments?”. This is what is called the battery capacity. It is the battery capacity that decides the back up hours. It is expressed in Ah (Ampere Hours).
In the market batteries with capacity of 100 Ah,150 Ah, 180 Ah etc. are readily available. So how to decide which one do you need? To find this out lets do a reverse calculation. Consider that you need a battery that provides back up for 3 hours.
Battery capacity = Power requirement (in watts) * Back up hours ( in hrs) / Battery Voltage (in volts)
Battery Capacity = (535 * 3) / 12 = 133 Ah
** Value of Battery voltage is taken 12V
Therefore a battery with a capacity of 130 Ah will work for you.
So if you want to run 3 fans, 3 tube lights , 1 CFL and 1 TV for 3 hours during power failure you would need 800VA inverter and 130 Ah battery.
By understanding this simple calculation you not only save yourself from the misleading information shared by inverter dealers but also help yourself in taking correct decision.

Which is the latest inverter technology in 2022 in India?
As the technology is evolving in the inverter space, higher efficiency and reciprocative solutions are making the overall energy ecosystem far more stable. For the less than 2KW to 3 KW requirements, MPPT based inverters are the best for smaller residential applications. With the efficiency as high as 96%, MPPT based inverters are most preferred solutions.
As the power requirements are on the rise, so are the solutions, like high frequency inverters or string inverters, which are customizable and are capable of delivering stable results under stress conditions. These high frequency inverters have amazing capabilities with lead acid batteries and Lithium ion batteries alike. Further more the high frequency inverters are light weight and hence can be mounted on walls, and more importantly are IoT based which makes them smart and efficient. These high frequency inverters are best use case for large to very large solutions like bigger homes or commercial locations.
To make the best quality inverter solution reach the last mile, Loom Solar is offering a complete range of inverters from 50W to 100KW, making it a one stop solution for inverters

Superb, Thanks Mr. Right
Thanks
My Grateful thanks for updated information. This has given me inspiration to buy one for my home use. Best Regards, Arvind Gaikwad
While calculating,
Battery Capacity = (535 * 3) / 12 = 133 Ah. You must consider power of inverter(i.e 765W) rather than 533 W.
Thanks for sharing the information.
Its really great information,thanks for sharing this blog,keep updating more threads, https://www.demoport.in/home-products-services/solar-water-heaters-inverters.php
Thanks a lot for explaining in a very simple language. Really helped me in making buying decision for my office.
Great article. Nice and simple explanation.
for 1fan, 1 tube light, 1televson, 1a/c, 1computer how much we want
good information
good, it’s useful;
thanks for this helpful article.. this will help me to buying a new inverter and battery…
very nice information thank q
thanks a lot for valuable explanation
THANK U FOR YOUR GOOD INFORMATION
Learnt how to calculate the inverter & battery need as this will help to verify whether the dealers are telling us the right info or not. Great to go thru the article!!!
HI,
i want to know whether i can run a 0.5 hp (500w) well motor using my current inverter without any extra load. My current inverter is sukam falcon plus 1600va(24v with 150 ah battery)…
Perfect Explanation
Buy inverter battery of the same of manufacturer of inverter. because that inverter battery is more suitable for the inverter.

MR. RIGHT MY INVERTER IS LEAKING CURRENT IN EACH SOCKET WHEN THERE IS POWER CUT. IT WORKS WELL WHEN I SWITCH ON ANY CFL. KINDLY HELP.
“But we all know that 100% or ideal conditions don’t exist in real. Most inverters have the efficiency range from 60 % to 80%. This efficiency is also called power factor of an inverter and is simply the ratio of power required by the appliances to power supplied by an inverter.

Power Factor is NOT related to efficiency of the Inverter.
It is related to the reactive power of the load connected (ceiling fans, lights etc.)
You need to calculate the individual VA consumption of all the loads and add them together.
Perfect point to point explanation.
your formulas where of great help. thank you for helping me decide which
inverter to buy.
It gives more information to the people who had less knowledge in this field. So much useful with this information while buying inverters in shop. thank u sir.
I am thinking about to buy a new inverter battery. But not sure what would do best for everything. Have spent a lot of time on reviews but it almost seems like a draw right now. But review this video to be honest my confusion is clear, Thanks.
