≈ 1.8 days (12h/day) · Safe motor start buffer (93.8% margin).
pellet stove running (220 W max) and start-up (750 W max) draw fit the EcoFlow DELTA Pro 3's 4,000 W continuous / 8,000 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: 25W (13.4% of total draw)
Provides 4× CEE 7/3 (230V), 1× IEC Commando (32A), 1× Commando (16A/32A) (120/240V 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) (93.8% worst-case surge margin).
Wall AC fast charge at up to 3000W (70m to 80%, 95m to 100%).
Safe envelope verified: Starting surge (500W) remains comfortably below the 8000W surge trip line, with steady-state operation settling into the safe continuous zone at 150W.
About 21.9 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 EcoFlow DELTA Pro 3 then draws about 187 W from its battery, including 25 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 15.6 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 EcoFlow DELTA Pro 3's 8,000 W surge rating, with 91% headroom even in the worst case.
On wall power: about 70 minutes to 80% and 95 minutes to full (EcoFlow figures). With its maximum 2,600 W of solar input connected, expect about 2,080 W in full sun, so a full recharge takes roughly 2.1 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 EcoFlow DELTA Pro 3 and the EcoFlow DELTA Pro 3 plugged into the wall, it switches the pellet stove to battery in about 10 ms when the grid fails (EcoFlow calls this UPS mode).
