FAQ
How long will the EcoFlow DELTA 2 Max run a refrigerator?
Around 12 hours for a full-size refrigerator averaging 150W, assuming ~85% inverter efficiency. Actual runtime depends on the fridge's compressor duty cycle and ambient temperature.
Does the EcoFlow DELTA 2 Max use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 3,000 cycles to 80% capacity — roughly 8+ years of daily cycling.
What solar panels work with the EcoFlow DELTA 2 Max?
Any panel (or array) within its 11-60V MPPT voltage window and up to 1000W, connected via XT60. Staying inside the voltage window matters more than matching wattage.
How fast does the EcoFlow DELTA 2 Max recharge from a wall outlet?
About 53 minutes from 0 to 80% on AC power.
