How long will the BLUETTI AC180 run a sump pump?

About 12 hours from a full charge. A sump pump averages about 80 W (800 W running, on about 10% of the time), and the 1,152 Wh battery gives about 979 Wh after inverter losses. That is 8.2% of the battery an hour.

Will the BLUETTI AC180 start a sump pump?

Yes. It needs about 2,100 W for a moment when the pump starts, and the BLUETTI AC180 is rated for 2,700 W surge, 1.3 times that. Avoid starting other motors at the same moment.

How much of the battery does a sump pump use in a day?

About 1,920 Wh a day (80 W × 24 hours), more than the 979 Wh the BLUETTI AC180 can deliver, so plan to recharge every 12 hours.
