Startup and running loads are different
Igniters can draw more power for a short time, while steady operation is usually lower.
Specialized runtime calculator
Estimate pellet stove backup runtime with ignition energy, steady running watts, and output checks.
Pellet stoves are not a simple constant load. Startup ignition and steady blower/auger running power should be handled separately.

Quick targets
Igniters can draw more power for a short time, while steady operation is usually lower.
Use manufacturer instructions for shutdown behavior during outages.
It depends on running watts, startup draw, battery size, and whether the station can handle startup output.
Yes, especially for smaller batteries, but steady running load usually dominates longer runtimes.
This calculator estimates electrical runtime and sizing. Actual results can change with device model, load variation, battery age, temperature, inverter idle draw, charge level, reserve settings, and manufacturer limits. Verify safety-critical loads with the device and power station documentation.
