FAQ
How long will the Yoshino B330 SST run a refrigerator?
About 5 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.
Can the Yoshino B330 SST start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 330 W output (no separate peak published). That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
