BLUETTI Elite 320 vs EcoFlow DELTA Pro
Technical comparison · Home backup
Two LFP home power stations, 3.2 and 3.6 kWh: what separates them is the power you can ask of them and how they take over when the grid drops. On the manufacturer's declared figures, 1800 W against 3600 W continuous, and a 10 ms switchover (UPS) against 30 ms with a gap (EPS).

The differences that matter
- Continuous output, 1800 W vs 3600 W (peak 3600 W vs 7200 W) → how many appliances you keep on together.
- Maximum charge power, 1.44 kW vs 2.875 kW → in theory about 2 h 15 min against 1 h 15 min to fill the battery, at full power and without losses.
- Solar input, 1000 W vs 1600 W → how many panels you can connect to recharge from the sun.
Which one to choose
Choose BLUETTI Elite 320 if…
You want a unit that stays in line and takes over in 10 ms, and a load within 1800 W is enough. You get a 5-year warranty and 34 kg to move; you give up two AC outlets (2 against 4).
Choose EcoFlow DELTA Pro if…
You want to run several appliances together from the four AC outlets, and the battery can be expanded. You accept 45 kg, a 3-year warranty and a 30 ms switchover with a short gap instead of continuity.
