The differences that matter
- 3.2 kWh vs 1.024 kWh → how long the same 1800 W load runs before it shuts off (values as declared by the manufacturer).
- 34 kg vs 12 kg → one you roll on wheels, the other you carry by hand.
- Solar input 1000 W vs 500 W → how much sun comes in, hence recharge time from panels.
- 10 ms continuity vs 30 ms backup with a gap → which equipment rides through the switchover without restarting.
Which one to choose
Choose BLUETTI Elite 320 if…
you want to keep loads up to 1800 W running for longer, with a declared 3600 W peak, 1000 W of panels and a declared 10 ms continuity switchover. It has wheels and a handle for its 34 kg. The trade-off: only two mains sockets and a declared idle draw of 10 W.
Choose EcoFlow DELTA 2 if…
you need something you carry by hand, 12 kg, with four mains sockets and the option to add batteries. The trade-off: 1.024 kWh, 500 W of solar input and, in backup, a declared 30 ms gap (EPS).
