FAQ
How long will the Generac GB1000 run a refrigerator?
About 20 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.
Can the Generac GB1000 start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 3200 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
