≈ 2.8 days (24h/day) · Safe motor start buffer (91.9% margin).
chest freezer running (165 W max) and start-up (950 W max) draw fit the EcoFlow DELTA Pro 3's 4,000 W continuous / 8,000 W surge ratings.
5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)
10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)
16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)
≈ 2.8 days (24h/day)
System standby power: 25W (41% 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 all standard household appliances.
Inductive motor/compressor load with 5.7× starting surge (motor inrush) (91.9% worst-case surge margin).
Wall AC fast charge at up to 3000W (70m to 80%, 95m to 100%).
Safe envelope verified: Starting surge (650W) remains comfortably below the 8000W surge trip line, with steady-state operation settling into the safe continuous zone at 115W.
About 67 hours on AC power, with the chest freezer averaging 33 W (10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)). The EcoFlow DELTA Pro 3 then draws about 61 W from its battery, including 25 W for the inverter itself. Best case: about 3.4 days (5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)). Worst case: about 50 hours (16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)).
Yes. The chest freezer's start-up peak of about 650 W (up to 950 W) fits within the EcoFlow DELTA Pro 3's 8,000 W surge rating, with 88% headroom even in the worst case.
That simple division gives 5.1 days, but the EcoFlow DELTA Pro 3's inverter draws about 25 W whenever its AC outlets are on. At this light load that's 41% of everything the battery supplies, and inverter conversion losses take a further share. The idle figure comes from EcoFlow.
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.
