Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it). † Its output covers the start, but no surge rating is listed.

Hours are nonstop pumping; the pump only runs while water comes in, so in most storms it lasts much longer.

Can the Apex 300 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 Apex 300 has a 3,840 W output (no surge rating is listed). 1/3 hp sump pump: likely, though no surge rating is listed; check with BLUETTI; 1/2 hp sump pump: likely, though no surge rating is listed; check with BLUETTI.

How much an hour takes

An hour of a 1/3 hp sump pump running nonstop uses about 800 Wh, about 34% of the Apex 300’s usable 2,350 Wh. At its 2,400 W solar input and our 75% assumption, strong sun puts about 1,800 Wh an hour back into the battery.

Keep the station dry and above any flood level.
