The differences that matter
- Energy 2.048 kWh vs 1.024 kWh; expandable to 10 kWh vs 5 kWh → with the same 1000 W solar input on both, in theory and without losses, about 2 hours against about 1 hour to fill them.
- Continuous output 3000 W vs 1800 W; maximum charge power 2.3 kW vs 1.5 kW → a continuous load above 1800 W (declared peaks 6000 W vs 3600 W) is beyond the Plus, and from the mains the Max Plus takes in more power.
- Warranty 3 years vs 5 → the smaller model is covered two years longer.

Which one to choose
Choose EcoFlow DELTA 3 Max Plus if…
you want a 2 kWh reserve that can grow to 10 kWh, with charging up to 2.3 kW. You accept 22.1 kg and a 3-year warranty, against 5 for the Plus.
Choose EcoFlow DELTA 3 Plus if…
a 1 kWh reserve is enough and weight matters: 12.5 kg and 39.76 × 28.36 × 20.2 cm. You accept continuous power capped at 1800 W and expansion to 5 kWh rather than 10, in exchange for the longer warranty.
