Sump pump hours on the R4000
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
Hours are nonstop pumping; the pump only runs while water comes in, so in most storms it lasts much longer.
Can the R4000 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 R4000 has a 6,000 W surge. 1/3 hp sump pump: covers it; 1/2 hp sump pump: covers it.
How much an hour takes
An hour of a 1/3 hp sump pump running nonstop uses about 800 Wh, about 27% of the R4000’s usable 2,938 Wh. At its 2,000 W solar input and our 75% assumption, strong sun puts about 1,500 Wh an hour back into the battery.
Keep the station dry and above any flood level.
