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

very very informitive..it made me practically aware about theory i read in physics….thanks
Very good information , very much useful
Thank you so much sir this is what I was searching in the whole net I got it from this site a whole information thanks a lot.
hey this is great that i know many thing i will have great knowledge
Thanks for this best blog
Much needed information I was looking for. thank you for your post.
good one keep it up
thanks for the information
Thank you very much for your article. i was looking for the battery to buy and found this article. I think we need to see the characteristics like warranty and price for the first time!
Which one is better microtek or amaron ? plz reply.
You can best inverter battery online at Lockthedeal based on energy requirements.
You can Batteries at a wholesale rate that too directly from Dealers and Retailers
nice post. I really appreciate your efforts for creating such an informational and helpful post. keep up the good work.
A ceiling fan is just one of the absolute most important appliances at a household. It’s also usually also among the most neglected appliances. The ideal fans in India ought to consist of features like saving electricity, sweeping a bigger surface area and also a lot more than only the simple function of moving air.
Fans are being used since a long time for you to circulate air while in the surrounding. It is the cheapest, most ordinary method to increase air flow within an room plus is effective for hot and cold weather. It brings the temperature down of its environment by 7 degrees, making the place warmer.
Thank s for the lucid explanation.
Divya you described so well each and everything in detail…!!!! Thank you so much.
1 0 systems+ 2 fan +2 tube light couid you suggest from best product mam
Thank you for explaining in detail.
Thanks for the article
Please, what will happen to the inverter and the battery when the load you are using is too lesser to inverter capacity…..
Assuming you have 2kva inverter and you are using load like 550wattages on it?
Thanks of sharing your experience and tips I will remember this article whenever I go for buying the battery usually I need battery for UPS
this content is just copied word to word from luminous website. Divya – try to create your own content to earn money not by copying
most of the inverters in market sucks
I guess 130 Ah battery won’t be enough for 535 W load, we need to take DOD of battery and battery efficiency into consideration. Battery sizing will be bellow :
=(535*3*100/80*100/85)/12 = 196 Ah
VRLA Battery DOD- 80%
VRLA Battery Efficiency – 85%
I think you are right
Great article. Explained in very concise way. Only what is needed. No frills. I love it.
Good article. Keep it up
The complete info I got from this post is best for me cause I was looking to get one inverter for home.
