The VA rating is the wattage of an inverter measured in volts and amps. The higher the number, the more power it can provide at a given time. It's important to know your VA rating when purchasing an inverter for your home or business because you want to make sure that you are getting enough power for what you need.
The following calculator helps you calculate the VA rating of the inverter. Just input the appliance load that you want to connect to an inverter and the efficiency of the inverter (in general 80% if purchased from top brands like luminous, amaron, exide)
Note: Use this calculator to use calculate your appliance load requirement.
