How Long Will the EcoFlow Delta Pro Run a Sump Pump (1/3 HP)?

Updated 2026-10-17 · Yes

About 15 hours. The EcoFlow Delta Pro stores 3600Wh, and a sump pump (1/3 HP) averages about 200W because it cycles on roughly 25% of the time.

Recharging with solar

The EcoFlow Delta Pro accepts up to 1600W of solar input. In real conditions that harvests about 6 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A sump pump (1/3 HP) uses about 4.8 kWh a day at 24 hours of use, so with enough panels and good sun the EcoFlow Delta Pro can run it indefinitely.

Tips

  • Sump pumps run in short bursts; how often depends on how much water is coming in. The motor start is the main hurdle.
  • You’ll still have about 2800W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The EcoFlow Delta Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
