How Long Will an Anker SOLIX S5000 Run a Well Pump?
About 4.3 h for a 1/3 hp well pump (EWEB figure, 1,000 W), by our math: 5,024 Wh × 0.85 ÷ 1,000 W. Across the cases below: 4.3 h to 5.7 h.

Well pump hours on the S5000
| Case | Watts | On the S5000 |
|---|---|---|
| Well pump (Idaho Power figure) (Idaho Power) | 750 W | 5.7 h |
| 1/3 hp well pump (EWEB figure) (EWEB) | 1,000 W | 4.3 h |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it). The S5000 goes on sale Oct 27.
The pump only runs while water is drawn. Many well pumps run on 240 V and are wired into the panel; a station’s 120 V outlets can’t run a 240 V pump.
Can the S5000 start it?
EWEB’s chart lists about 3,000 W in total to start a 1/3 hp well pump (EWEB); Portland General Electric warns the start can reach six times the running watts (PGE). The S5000 has a 8,000 W surge. Well pump (Idaho Power figure): covers it; 1/3 hp well pump (EWEB figure): covers it.
How much an hour takes
An hour of a 1/3 hp well pump (EWEB figure) running nonstop uses about 1,000 Wh, about 23% of the S5000’s usable 4,270 Wh. At its 3,000 W solar input and our 75% assumption, strong sun puts about 2,250 Wh an hour back into the battery.
A wired-in pump needs a transfer switch installed by a professional; never connect a backup to house wiring yourself.
