≈ 1.8 days (12h/day) · Safe motor start buffer (93.1% margin).
pellet stove running (220 W max) and start-up (750 W max) draw fit the Goal Zero Yeti PRO 4000's 3,600 W continuous / 7,200 W surge ratings.
Modulated low fire: motorized auger feed and exhaust fan running continuously (100 W)
Medium fire heat setting: continuous combustion blower, room fan, and intermittent auger (150 W)
Startup ignition cycle: ceramic electric glow igniter element active for first 15 minutes (500 W peak)
≈ 1.8 days (12h/day)
System standby power: 22W (11.9% of total draw)
Provides 4× CEE 7/3 (230V), 1× IEC Commando (32A) (120V 60Hz).
Pure sine wave inverter output. Safe for sensitive medical electronics and variable-speed motors.
Inductive motor/compressor load with 3.3× starting surge (motor inrush) (93.1% worst-case surge margin).
Wall AC fast charge at up to 1800W (120m to 80%, 150m to 100%).
Safe envelope verified: Starting surge (500W) remains comfortably below the 7200W surge trip line, with steady-state operation settling into the safe continuous zone at 150W.
About 21.7 hours on AC power, with the pellet stove averaging 150 W (Medium fire heat setting: continuous combustion blower, room fan, and intermittent auger (150 W)). The Goal Zero Yeti PRO 4000 then draws about 184 W from its battery, including 22 W for the inverter itself. Best case: about 31 hours (Modulated low fire: motorized auger feed and exhaust fan running continuously (100 W)). Worst case: about 15.3 hours (Startup ignition cycle: ceramic electric glow igniter element active for first 15 minutes (500 W peak)). At 12 hours a day, that's about 1.8 days.
Yes. The pellet stove's start-up peak of about 500 W (up to 750 W) fits within the Goal Zero Yeti PRO 4000's 7,200 W surge rating, with 90% headroom even in the worst case.
On wall power: about 120 minutes to 80% and 150 minutes to full (Goal Zero figures). With its maximum 3,000 W of solar input connected, expect about 2,400 W in full sun, so a full recharge takes roughly 1.8 hours of full sun, so it can refill in a single day with 4 peak sun hours.
It can act as a backup supply: with the pellet stove plugged into the Goal Zero Yeti PRO 4000 and the Goal Zero Yeti PRO 4000 plugged into the wall, it switches the pellet stove to battery in about 10 ms when the grid fails (Goal Zero calls this UPS mode).
