Size a standby generator from your appliances' running and starting watts, free online.
À propos de cette calculatrice
Add the running watts of everything you want to power at once, then add the single largest starting surge (motors and compressors start at 2–3× running watts). Add 20% headroom. kVA = kW ÷ 0.8 (typical power factor). Enter each appliance as "name: running watts, starting watts".
