FAQ
Can the Generac Protector 50kW Diesel (RD05033) start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 50000 W output (no separate peak published). That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
