DJI Power 2000 vs EcoFlow DELTA 2 Max
Technical comparison · Home backup
Two LFP stations with the same capacity, 2.048 kWh, and nearly the same weight, 22 and 23 kg: capacity does not decide here. What counts is how far you can grow them, how many panels you can connect and whether the output interrupts devices (manufacturer-declared values).

How we assign awards →No awards in this tier.
The differences that matter
- Expandable to 22.528 against 6.144 kWh → the first can grow into something close to a home store, the second stays a smaller reserve.
- 1800 against 1000 W solar input → with more panels the first fills in a day, the second accepts less.
- 3000 against 2400 W continuous → the first carries bigger loads together.
- 10 ms continuity against a 20 ms gap → a computer stays on with the first, may reboot with the second.
Which one to choose
Choose DJI Power 2000 if…
you plan to start at 2 kWh and grow: with extra batteries it reaches 22.528 kWh. It takes up to 1800 W of panels, carries 3000 W continuous and in continuity (UPS) mode switches over in 10 ms, for a PC that must not reboot. The fan is stated at 29 dB. The trade-off is small: from the mains it charges at 2.2 kW at most rather than 2.4.
Choose EcoFlow DELTA 2 Max if…
loads up to 2400 W are enough, with a stated 4800 W peak for motors starting up, and a 1000 W solar array is what you have. It can be taken to 6.144 kWh with extra batteries. What you accept: backup has a 20 ms gap (EPS), which a running computer may not forgive, and the growth ceiling is much lower.
