# Inverter size calculator

Size an inverter from simultaneous appliance loads, covering continuous watts, VA via power factor, motor surge, safety margin, and battery current.

List the loads you would run together to size the inverter.

The result is a planning estimate from nameplate figures. It does not choose between pure-sine and modified-sine waveforms, it covers no electrical code, and it says nothing about wiring, earthing, or how the inverter connects to a supply. High battery current is the usual reason to move from 12 V to 24 V or 48 V. Everything is computed in this tab and nothing is uploaded.
