1. How to choose the right inverter?

A: You choose the inverter according to the rated power of electrical appliance, in general, the actual power of inverter is lower than the rated power, so you should choose the higher power than the rated power marked in the appliance. The efficiency of our inverter is higher than 93%, you can calculate the power by this formula:

 Rated power=rated current×rated voltage

Actual power=Rated power×efficiency

2. How to choose the right battery?

A: battery capacity=rated power/input voltage×working time

Such as: A12v to 220v inverter need work 2 hours, the battery capacity should be:

1000w/12v×2 hours=167AH

The voltage of battery should be as the same as the inverter’s. that means the 12v to 220v inverter should buy the 12v battery. and so on.
