The maker rates it at 12 hours at 50 % load (about 1,700 W). A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Starting surge matters more than running watts: this unit is rated 4000 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
