What size power station do I need for Pellet stove?
Pellet stove
Default appliance profile before model-specific measurements.
Using the supplied baseline estimate, the pellet stove uses about 936 Wh per day: 120 W for 12 hours at a 65% duty cycle. A conservative one-day target is about 1,359 Wh of nominal battery capacity, based on 88% inverter efficiency, 90% usable capacity, and a 15% reserve margin.
The inverter should support at least 500 W for the stated startup demand. Actual consumption may vary by about ±30% and by appliance model, settings, ambient conditions, and load; no model-specific measurement is provided.
- Battery sizing: Choose at least 1,359 Wh nominal capacity for the default one-day target; among the listed sizes, 1,500 Wh exceeds that target.
- Inverter sizing: Allow for at least 500 W of startup or surge demand, not just the 120 W running estimate.
- Validate when possible: A plug-in power meter or manufacturer energy label is preferable, because the supplied figures are baseline estimates rather than measurements of a specific stove.
Using the default load profile, pellet stove consumes about 936 Wh/day. A conservative one-day battery target is about 1359 Wh nominal capacity, while the inverter should cover at least 500 W of startup demand.
Assumptions behind the calculation
- Running draw: 120 W
- Startup/surge: 500 W
- Default use: 12 h/day
- Duty cycle: 65%
- Usage uncertainty: ±30% before model-specific measurements
Actual energy use varies by appliance model, ambient conditions, settings and load. A plug-in power meter or manufacturer energy label is preferable when available.
Runtime by battery size
| Station capacity | Continuous-draw runtime | Default usage profile |
|---|---|---|
| 300 Wh | 2 h at continuous draw | 0.3 default-profile days |
| 500 Wh | 3.3 h at continuous draw | 0.4 default-profile days |
| 1000 Wh | 6.6 h at continuous draw | 0.8 default-profile days |
| 1500 Wh | 9.9 h at continuous draw | 1.3 default-profile days |
| 2000 Wh | 13.2 h at continuous draw | 1.7 default-profile days |
| 3000 Wh | 19.8 h at continuous draw | 2.5 default-profile days |
