What will an EcoFlow DELTA Pro 3 run? (EU 230 V)

A “4,000 W” power station is two numbers wearing one label. Watts are the ceiling on what you can switch on at once; watt-hours are how much energy is in the battery. The EcoFlow DELTA Pro 3 holds 4,000 W and stores 4,096 Wh on the nameplate — and those two facts answer two different questions.

This page answers the first one. We have found no published depth of discharge or inverter efficiency for the EU 230 V build. Without one of the two there is no defensible usable-capacity figure, and this page will not turn the nameplate into hours.

No usable-capacity figure for the EU 230 V build

EcoFlow states a nameplate watt-hour number for it, and we have found no published depth of discharge or inverter efficiency for the EU 230 V build. Dividing the nameplate by a load would be wrong by 20–35%, so this page shows the nameplate for what it is and refuses to turn it into hours.

What EcoFlow DELTA Pro 3 runs

Every row is a live calculation against this machine's continuous output, surge ceiling and inverter waveform — running watts, start-up inrush and duty cycle on the appliance side. Of 38 appliance profiles, 28 run, 6 are a tight fit and 4 are out of reach. The percentage is the load as a share of continuous output; anything past 82% drops out of the green.

Solar panels this machine can legally take

The binding constraint is voltage, not watts: open-circuit voltage RISES as it gets colder, and an array that is fine at noon can be over the MPPT ceiling at dawn. Each row is the engine's largest legal array for this station, with Voc corrected to -10 °C ambient . Only panels whose datasheet publishes a voltage temperature coefficient are evaluated — the others cannot be corrected, and an under-corrected array is what destroys an MPPT input.

Every field we hold on this machine

Each figure carries the tier it came from and the date it was checked. A blank is never left blank: a field we have found no figure for says so, and a field two manufacturer sources disagree about says that instead of picking one.

AC output

What the inverter can hold, what it can start, and what shape the wave is.

EcoFlow DELTA Pro 3 (US 120 V) Same model on 120 V mains — different outlets, and the specs below are not interchangeable. EcoFlow DELTA 2 Max (EU 230 V) 2,400 W continuous against this machine's 4,000 W.

Each link goes to that machine's own record. Every record holds the same fields in the same order and states the same tier and date beside each one, so two of them read side by side compare cleanly.

Questions people ask about this machine

Will an EcoFlow DELTA Pro 3 run a full-size refrigerator?
Yes. Against the EU 230 V record, the full-size refrigerator draws 55 W running · 286 W at start-up — 1.4% of this machine's continuous output. That verdict is a calculation from running watts, start-up surge and inverter waveform, not a lookup, and the full working is one click away in the table above.
Why can't an EcoFlow DELTA Pro 3 run an inverter window air conditioner (U-shaped)?
On the EU 230 V record the binding constraint is the mains standard, so nothing about this machine's capacity enters into it. The inverter window air conditioner (U-shaped) draws 667 W running · 667 W at start-up, and a larger machine on the same output voltage would fail in exactly the same way. What has to change is the output voltage, not the size of the machine.
How long will an EcoFlow DELTA Pro 3 run my appliances?
We will not put a number on it, and that is deliberate. A runtime needs a usable-capacity figure, and we have found no published depth of discharge or inverter efficiency for the EU 230 V build — only a nameplate watt-hour rating. Dividing that nameplate by your load produces a confident-looking figure that is typically 20–35% too high. What this page gives you instead is every load's energy rate in watt-hours per hour, which needs no battery figure at all and is the number you actually size against.
Can you take an EcoFlow DELTA Pro 3 on a plane?
No. At 4,096 Wh it is far above the 160 Wh ceiling that airlines apply to lithium batteries in the cabin, and lithium batteries of this size are not accepted in checked baggage either. The 100 Wh / 160 Wh thresholds come from the IATA dangerous-goods rules that carriers implement; check your airline before travelling, because the approval step above 100 Wh is theirs to give.
Is the EU EcoFlow DELTA Pro 3 the same as the US one?
No, and we keep them as two separate records for that reason. This one is built for 230 V mains and the US version for 120 V, which changes the outlets, the certifications and the charging figures. Where the brand publishes different numbers for the two, this page shows only the ones for the EU 230 V version.
