Can an Anker SOLIX C300 run a sump pump (1/2 hp)?
No — the Anker SOLIX C300 can't run a sump pump (1/2 hp).
The sump pump (1/2 hp) draws about 1,050 W running, with a 2,150 W startup surge; the C300 delivers 300 W continuous and 600 W surge. That's not enough continuous output.

Common questions
Can the Anker SOLIX C300 run a sump pump (1/2 hp)?
No. A sump pump (1/2 hp) needs 1,050 W continuous and a 2,150 W startup surge, but the Anker SOLIX C300 only delivers 300 W continuous and a 600 W surge — so it can’t sustain the running load. You'd want a larger unit.
