FAQ

How long will the Anker SOLIX C300 DC 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 Anker SOLIX C300 DC start a sump pump or well pump?

Starting surge matters more than running watts: this unit is rated 300 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.
