FAQ

How long does the Generac GP3600 run on a tank?

The maker rates it at 9.3 hours at 50 % load (about 1,800 W) on a 3.7-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.

Can the Generac GP3600 start a sump pump or well pump?

Starting surge matters more than running watts: this unit is rated 4500 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
