The differences that matter
- 3.2 kWh at 1800 W against 2.048 kWh at 2400 W (manufacturer's declared values) → more reserve on one side, more instant power on the other.
- Maximum charge 1.44 kW against 2.3 kW → a full recharge is quicker on the EcoFlow.
- Solar input 1000 W against 500 W → with panels powerful enough, the BLUETTI recharges from the sun in half the time.
- Warranty 5 years against 3 → on both it ends before the cycle limit: two more years of cover.
Which one to choose
Choose BLUETTI Elite 320 if…
you have to cover many hours of moderate loads and have solar panels up to 1000 W of input. It has 3.2 kWh, a 5-year warranty and wheels with a handle for its 34 kg. The trade-off: 1800 W continuous, 3600 W peak, only two mains outlets and a maximum mains charge of 1.44 kW.
Choose EcoFlow DELTA 3 Max if…
you need to run more demanding appliances or several at once: 2400 W continuous (4800 W peak), 4 mains outlets, charging up to 2.3 kW and 20.3 kg to move. The trade-off: 2.048 kWh of capacity, 500 W of solar input and a 3-year warranty.
