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
- Maximum solar input 1800 W vs 500 W → the first takes a large array, the second refills slowly from the sun
- Continuous output 3000 W vs 1800 W → the first feeds several large loads together
- Noise 29 dB vs 45 dB → indoors the second is clearly audible, the first much less so
Which one to choose
Choose DJI Power 2000 if…
A system that runs more loads together and can grow to 22.528 kWh by adding modules; it charges from 0 to 80% in 45 minutes against 60 and its USB-C port reaches 140 W. The trade-off is a bigger body (44.8 × 22.5 × 32.4 cm) and 22 kg.
Choose EcoFlow DELTA 3 1500 if…
A more contained 1.536 kWh store with a declared IP54 rating, 21.3 cm wide and expandable to 5.5 kWh. The trade-off is less power, less solar input and a slower 0–80% charge.
