How to use the Inverter Sizing
The Formula
Inverter W = peak load × (1 + margin ÷ 100). Motors and compressors can draw 2–3× surge at startup—consider a higher margin if you have pumps or fridges.
Practical Example
Inverter datasheets list continuous and peak (surge) watts. Size so peak rating covers motor start surges, not just steady-state load.
