A well pump stops when the power drops, and the EcoFlow DELTA Pro 3 answers that with 4,000 W and 240V output. The Anker SOLIX F3800 Plus gives 6,000 W with 240V output too. The Jackery HomePower 3000 covers 120V pumps with 3,600 W and a 7,200 W surge.
This guide sizes the three stations from the makers’ published specs, current in November 2026. PowerPicked Editorial has not run tests on any of the three stations here.
Wh counts stored energy, and one watt-hour is written Wh. Power counts in watts, and one watt is written W. AC output is the plug-in power for the well. Solar input is the panel power a station takes in. 240V output is the higher-voltage power some pumps need.
