Can the EcoFlow DELTA Pro (3,600Wh) Run a Full-Size Fridge?
Yes. With 3,600Wh of LiFePO4 battery capacity (3,060Wh usable after 85% AC inverter conversion) and a 3600W continuous / 7200W surge pure sine wave inverter, the EcoFlow DELTA Pro (3,600Wh) should run a Full-Size Kitchen Refrigerator (Energy Star) for approximately 44.3 hrs (~1.8 days) on a single charge.
- Usable Watt-Hours: The EcoFlow DELTA Pro (3,600Wh) holds 3600Wh, which yields about 3060Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- Full-Size Fridge Duty Cycle: While active, a Full-Size Fridge pulls 160W (with a 650W startup spike). Over a multi-hour period, its 38% duty cycle averages ~61W per hour (plus ~8W inverter standby overhead).
- Tip: Never multiply a refrigerator's 160W sticker rating by 24 hours straight! Because the insulated cabinet holds cold air, the compressor only cycles on about 35%–40% of the time (~1,450Wh per 24 hours). However, your power station MUST handle the 600W–800W startup compressor surge.
