DC-to-AC useful power calculator

The conversion approximation is about 98%; net system efficiency also includes reforming, pumps and other auxiliaries.

P_{\text{AC}} = \eta_{\text{inverter}} \times P_{\text{DC}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

P_{\text{AC}} = 0.98 \times 160 = 156.8

Symbol	Meaning	Unit
$P_{\text{AC}}$	AC output after inverter	kW
$\eta_{\text{inverter}}$	DC-to-AC conversion efficiency approximation	fraction
$P_{\text{DC}}$	DC input to inverter	kW

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
