Wood Pellet Stove (Igniter, Auger & Fan): Running Watts, 550W LRA Surge, Generator Size & LiFePO4 Battery Runtime
A Wood Pellet Stove (Igniter, Auger & Fan) requires 450 running watts (3.75A at 120V via a NEMA 5-15P plug) and spikes to 550 starting surge watts (1.2× LRA inrush). At a realistic 45% duty cycle (~203 Wh/hr net burn), you need a minimum 550W inverter or generator and at least 3,185 Wh (~249 Ah @ 12.8V) of LiFePO4 battery capacity for a 12-hour blackout. Our top-matched plug-and-play solar generator for a Wood Pellet Stove (Igniter, Auger & Fan) is the Bluetti AC200L.

Running Watts, LRA Surge & Field Sizing Guidance
Pellet stoves draw ~400W–500W for the first 10 minutes while the resistive hot-rod igniter lights the burn pot, then drop to just 130W–180W continuous for the auger and convection fans. A pure sine wave station with <20ms EPS/UPS switchover prevents smoke back-drafting if utility power drops mid-burn.
Waveform Verdict: Pure Sine Wave Mandatory (<3% THD)
Pellet stove control boards use phase-angle triac speed controllers for combustion blowers that buzz loudly and burn out on modified sine inverters.

Frequently Asked Sizing Questions: Wood Pellet Stove (Igniter, Auger & Fan)
How many watts does a Wood Pellet Stove (Igniter, Auger & Fan) use to start and run?
A typical Wood Pellet Stove (Igniter, Auger & Fan) draws 450 continuous running watts (3.75A at 120V via a NEMA 5-15P plug) and spikes up to 550 peak startup surge watts (1.2x running load). With a realistic 45% hourly duty cycle, it consumes approximately 203 Wh per hour.
What size solar generator or battery backup will run a Wood Pellet Stove (Igniter, Auger & Fan) overnight?
Accounting for 85% AC inverter conversion efficiency and 90% LiFePO4 usable depth-of-discharge (0.765 total factor), running a Wood Pellet Stove (Igniter, Auger & Fan) requires 1,062 Wh for 4 hours, 2,123 Wh for 8 hours, 3,185 Wh (~249 Ah @ 12.8V / ~63 Ah @ 51.2V) for 12 hours, and 6,369 Wh for 24 hours. Our top-matched solar generator for this load is the Bluetti AC200L.
Can a 1500W inverter start a Wood Pellet Stove (Igniter, Auger & Fan)?
Yes — provided the 1,500W inverter is a pure sine wave unit with at least 550W of peak surge capacity (most quality 1,500W–1,800W LiFePO4 stations handle 3,000W–3,600W motor surges), it will safely start and run a Wood Pellet Stove (Igniter, Auger & Fan) (450W continuous).
What size generator or inverter do I need for a Wood Pellet Stove (Igniter, Auger & Fan)?
Applying the NEC 20% continuous load safety headroom (540W continuous) and clearing the 550W startup surge requires a generator or battery inverter rated for at least 550 peak watts.
Does a Wood Pellet Stove (Igniter, Auger & Fan) require a pure sine wave inverter?
Yes — a pure sine wave inverter (<3% THD) is strictly recommended for a Wood Pellet Stove (Igniter, Auger & Fan). Pellet stove control boards use phase-angle triac speed controllers for combustion blowers that buzz loudly and burn out on modified sine inverters.
