Power cuts can be a huge inconvenience to anybody – be it a working professional or just someone who depends on gadgets and appliances for their work or leisure. They can not only cause you inconvenience but can disrupt your work and plans for the day.
Sadly, as much as we find power outages annoying, there’s nothing we can do to avoid them. However, what you can do is ensure a constant supply of electricity even when the power is out.

Wondering how?
The answer to all the questions and the solution to all your power-related problems is an inverter. This is why it is essential to select the right inverter size for home to ensure an uninterrupted power supply even during a power outage.
However, we understand that choosing the right inverter size for home can be challenging, especially when you are not accustomed to the basics of electronic devices, especially an inverter.
Worry no more because we are here to help you pick the right inverter size for home.
What is an Inverter? Why do you Need an Inverter?
An inverter is an electrical appliance that supplies power to your appliances with the help of an inverter battery. While an inverter battery stores the power when the power supply is readily available, an inverter converts this stored energy into electricity to supply it to your appliances.
The primary role of a home inverter is to turn Direct Current into Alternating Current. The energy stored in an inverter battery is in the form of a Direct Current. As the appliances in your home demand alternating current, an inverter converts the direct current stored in your battery into the alternating current; so that your appliances run as smoothly as possible.
Now that you know how a home inverter works, you must figure out why you need it.
It is simple. If you are a victim of frequent power cuts or live in a location that faces an acute power shortage, an inverter can provide you with electricity.
How to Pick the Right Inverter Size for Home?
Now that you know why an inverter is essential, we will discuss how you can pick the right inverter size for home.
Just so you know, you cannot just pick any inverter that you are recommended because of the numerous features the inverter carries. An inverter must be a well-thought decision. The inverter capacity for home use and other factors matters the most when selecting the right inverter size for home.
What Would be the Right Inverter Capacity for Home?
The right inverter capacity for home use is determined by your power requirements during a power outage. Your power requirements are calculated by the sum of the voltage the appliances need.
So, the first thing to do here is to decide how many appliances you want running during a power cut. Then, you need to know the voltage an appliance demands.
Supposing you want to operate 4 fans and 3 tube lights during a power cut.
Total Requirement: (75 Watts * 4) + (40 Watts * 3)
= 420 Watts
Once you are done calculating the power requirements, consider your inverter efficiency to calculate the VA rating of the inverter your home needs.
Please note you cannot find inverters with 100% efficiency in the market. So, if a manufacturer tells you that their inverters offer 100% efficiency, they’re tricking you.
Having said that, inverters in India offer 60-80% efficiency, which makes the power factor to be 0.7 (considering inverter efficiency to be 70%).
Now, divide the total requirement by 0.7
= 420/0.7 = 600 VA
This means you need to find an inverter that matches or is close to this number. As per the calculation, a 600VA inverter would be the ideal inverter size for home.
If you are buying an inverter, you also need an inverter battery. Just as your inverter size for home matters, inverter battery capacity for home matters too.
Here is how you can calculate that:
Inverter Battery Capacity for Home = Power Requirement * Backup Hours (Duration of power cut/ duration you need the inverter battery to supply power) / Battery Voltage in Volts (12V)
Going along the same line of calculation,
Inverter Battery Capacity for Home (Measured in Ah) = 420 * 3/ 12 = 105 Ah
As per this calculation, the right inverter battery capacity for home would be close to this number (105 Ah)
