SIZING TARGET

Pellet stove

Default appliance profile before model-specific measurements.

936 Wh daily energy500 W startup target1,359 Wh 1-day nominal target

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.
