EcoFlow DELTA Pro 3 vs EcoFlow DELTA 3 Plus
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 3 Plus costs $2950 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 300% more energy (4096Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 4400W more surge headroom (8000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 84.3 lb lighter (28.7 lb vs 113 lb).
EcoFlow DELTA Pro 3
The most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
