Can a Goal Zero Yeti 700 run a sump pump (1/2 hp)?

Q: Can the Goal Zero Yeti 700 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 Goal Zero Yeti 700 only delivers 1,000 W continuous and a 1,500 W surge — so it can’t sustain the running load. You'd want a larger unit.
