Can the BLUETTI AC180 Run a Sump Pump (1/3 HP)?
Yes. With 1,152Wh of LiFePO4 battery capacity (979Wh usable after 85% AC inverter conversion) and a 1800W continuous / 2700W surge pure sine wave inverter, the BLUETTI AC180 should run a Basement Sump Pump (1/3 HP Submersible) for approximately 7.6 hrs on a single charge.
- Usable Watt-Hours: The BLUETTI AC180 holds 1152Wh, which yields about 979Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- Sump Pump (1/3 HP) Duty Cycle: While active, a Sump Pump (1/3 HP) pulls 800W (with a 1800W startup spike). Over a multi-hour period, its 15% duty cycle averages ~120W per hour (plus ~8W inverter standby overhead).
- Tip: Sump pumps are all about STARTING SURGE. A 1/3 HP pump draws 800W while pumping, but demands 1,600W–2,000W for a split second to spin up the impeller against water pressure. Never use a power station rated below 1,800W continuous / 2,400W+ surge.
