What is the Difference Between kVA and kW in a Generator?
kVA vs kW in diesel generators: kW = kVA x 0.8 power factor. 500kVA gives about 400kW. Learn how to size correctly with PowerZone.
kVA is apparent power and kW is usable power. kW equals kVA multiplied by power factor, usually 0.8. A 500kVA generator therefore delivers about 400kW. Always size your generator using your load in kW plus motor starting demand.
