Sump pump hours on the R1500
| Case | Watts | On the R1500 |
|---|---|---|
| 1/3 hp sump pump (Honda) (EWEB) | 800 W | 1.2 h |
| 1/2 hp sump pump (EWEB) | 1,050 W | 56 min * |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it). * Covers the lower starting figure but not the higher one.
Hours are nonstop pumping; the pump only runs while water comes in, so in most storms it lasts much longer.
Can the R1500 start it?
Generator charts list about 1,500–2,100 W in total to start a 1/3 hp pump and 2,100–3,250 W for 1/2 hp (Honda) (EWEB). The R1500 has a 3,000 W surge. 1/3 hp sump pump: covers it; 1/2 hp sump pump: likely, but the start may be tight.
How much an hour takes
An hour of a 1/3 hp sump pump running nonstop uses about 800 Wh, about 82% of the R1500’s usable 979 Wh. At its 650 W solar input and our 75% assumption, strong sun puts about 488 Wh an hour back into the battery.
Keep the station dry and above any flood level.
