How do I calculate what size inverter I need?

Calculation:Fan Load= No x Watt =2×60=120 Watt.Fan Load=(No x Watt)/P.F=(2×60)/0.8= 150VA.Computer Load= No x Watt =1×200=200 Watt.Computer Load=(No x Watt)/P.F =(1×200)/0.8= 250VA.Tube Light Load= No x Watt =2×30=60 Watt.Tube Light Load=(No x Watt)/P.F =(2×30)/0.8= 75VA.Total Electrical Load=120+200+60 =380 Watt.More items…•
