What size power station for a pellet stove?
It needs a station with at least 180 W of continuous output and a surge rating of at least 425 W to start it. At the default 85% efficiency it takes about 1,694 Wh of rated capacity for 8 hours of running, and 5,082 Wh for 24 hours of running. 53 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 24 hours of running is the EcoFlow DELTA Pro Ultra (6,144 Wh).

The math
Worked with the typical figure, as the calculator does it.
- Output180 W running, so the station's continuous output must be at least 180 W.
- Surge425 W to start, so its surge rating must be at least 425 W.
- Average draw180 W: the running watts count for every hour it is on.
- A typical day180 W × 24 h = 4,320 Wh a day.
- 8 hours of running180 W × 8 h = 1,440 Wh usable, ÷ 0.85 = 1,694 Wh of rated capacity.
- 24 hours of running180 W × 24 h = 4,320 Wh usable, ÷ 0.85 = 5,082 Wh of rated capacity.
- On the EcoFlow DELTA Pro Ultra6,144 Wh × 0.85 = 5,222 Wh usable, ÷ 180 W = 29.0 h.
Stations that run it
Every power station in the data with this appliance alone plugged in, at 85% efficiency. Type the running watts from your own label and the table works it out again.
What moves the number
Fans, the auger and the controls run the whole time the stove burns: about 180 W. The start figure, 425 W, is the electric igniter at light up, which runs for several minutes rather than the moment a motor takes. A stove that keeps burning lights once, so the battery mostly sees the running figure.
