Can the EcoFlow River 2 Pro Run a Sump Pump (1/3 HP)?

Updated 2026-10-17 · Startup risk

Probably not reliably. Once running, a sump pump (1/3 HP) draws about 800W, within the EcoFlow River 2 Pro’s 800W rating. But its startup surge of roughly 2000W exceeds the station’s 1600W surge limit, so the inverter is likely to trip the moment the motor starts. If it does start, it would run for about 3.3 hours.

Recharging with solar

The EcoFlow River 2 Pro accepts up to 220W of solar input. In real conditions that harvests about 825Wh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can’t fully keep up. A sump pump (1/3 HP) uses about 4.8 kWh a day at 24 hours of use, more than the EcoFlow River 2 Pro’s best-case solar harvest. Solar will stretch the runtime but not sustain it.

Tips

  • Sump pumps run in short bursts; how often depends on how much water is coming in. The motor start is the main hurdle.
  • The EcoFlow River 2 Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ

Will the EcoFlow River 2 Pro run a sump pump (1/3 HP) overnight?

No. At about 200W average it runs out after 3.3 hours. For a full night you need at least 1900Wh of capacity.

How long does the EcoFlow River 2 Pro take to recharge with solar?

With its maximum 220W of solar input it refills in about 4.7 hours of strong sun. With a single 200W panel, expect about 5.1 hours of full sun.

Which power station can run a sump pump (1/3 HP)?

The Jackery Explorer 1000 (1002Wh, 1000W output) can, for about 4.3 hours. See the comparison table below for more options.
