To start with, you need to have a very clear understanding of the power requirements at your home or office or wherever you want to use the battery. One common mistake that most people make is that they do what they see others do without analyzing the facts. Just because your neighbour is using a certain inverter, you don’t necessarily have to use the same inverter. The power requirement at your home may be different from others. That is why you need to understand the basics of an inverter battery before making the decision to purchase it.


Here’s how you can do this:

1. Find the VA rating of the Inverter Battery

The basic way to understand an inverter battery is to check the volt ampere rating. The volt ampere rating is the voltage supplied to an electric equipment by the inverter. For inverters which operate with 100% efficiency, the power requirement of the appliance and the power supplied by the inverter is the same. However, you should know that there is hardly any inverter where you get a 100% efficiency in reality. In the most ideal cases, your inverter battery could have an efficiency range of 70% to 80%.

2. Find your power requirement

Calculate the total power that you require to run all your gadgets and appliances.Track the operational time of all your appliances. Now figure out the energy required by multiplying the total time with the total power rating of all your appliances. You can now easily determine the ideal inverter battery by comparing the energy rating of the battery with the value of the total power consumption.

3. Find the required battery size

Bare in mind that your battery has to be compatible with your inverter. In case the size of the battery is not the right fit for your inverter, it may not perform as efficiently. Extra tip: When you decide to get bigger appliances, you should check the size requirement of the inverter and the battery. You may need to upgrade to high performing inverters and batteries in such cases.
