Runtime = capacity × 85% (inverter losses) ÷ your daily energy. "Runs all at once" compares the sum of watts with the rated continuous AC output; motors and compressors can need 2-3 times their running watts to start. Capacity, output and prices were read on each manufacturer's US store on 2026-10-29. Methodology
