Can a Goal Zero Yeti 500X run a sump pump (1/3 hp)?

Q: Can the Goal Zero Yeti 500X 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 Goal Zero Yeti 500X only delivers 300 W continuous and a 1,200 W surge — so it can’t sustain the running load. You'd want a larger unit.
