La tua isola — France sizing tool

07 — Inverter

Sized on the expected load profile — the peak counts, not the average.

Expected maximum simultaneous load (W)

Add up the power of every appliance that could be on at the same time in the worst case.

Safety margin (%)

Extra on top of the calculated peak, for motor/compressor start-up surges.

Number of inverters in parallel

All the same size — the peak load (with margin) is split between them.

System AC voltage

400V three-phase requires 3 inverters in parallel (one per phase, above).

A design-wide choice, not per-inverter.
