What are the standard generator sizes?
The standard diesel generator sizes we supply are 10, 15, 20, 30, 40, 50, 60, 80, 100, 125, 150, 200, 250, 300, 400, 500, 650, 750, 1000, 1250, 1500, 2000, 2500 kVA. These are the standby ratings built by every major genset assembler, each with a matching engine, alternator and ATS panel.
kVA is the apparent power; kW is about kVA × 0.8. Choose the size so the generator runs at 50–80% of its rating, with headroom for motor starting and future loads. Work out your size with the kVA calculator or browse every model.
