Most capable Room-sized (1–3 kWh)
Highest technical score among the 21 sheets in the Home backup category (room-sized tier): 93/100.
How we assign awards →No awards in this tier.
The differences that matter
- Solar input, 1800 W vs 1000 W → with suitable panels, in theory about 1 h 10 min of full sun to fill it against about 2 h.
- Charge 0–80%, 45 vs 68 minutes → the declared 80% is reached sooner with the DJI.
- Maximum expanded capacity, 22.5 kWh vs 10 kWh → more than twice the room to grow.
- Warranty, 5 years vs 3 → the DJI Power 2000 stays covered two years longer.
Which one to choose
Choose DJI Power 2000 if…
you have a large array of panels and want to fill the battery in the middle hours of the day, or plan to add batteries over time. The trade-off is slightly more noise.
Choose EcoFlow DELTA 3 Max Plus if…
the unit sits in a bedroom or a study: 25 dB declared. Mains charging is slightly stronger too, 2.3 kW against 2.2 kW. The trade-off is a shorter warranty and slower solar charging.
