Can an Anker SOLIX C300 run a sump pump (1/3 hp)?

No — the Anker SOLIX C300 can't run a sump pump (1/3 hp).
The sump pump (1/3 hp) draws about 800 W running, with a 1,500 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 (1/3 hp)?

No. A sump pump (1/3 hp) needs 800 W continuous and a 1,500 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.
