EcoFlow DELTA Pro 3 vs Anker SOLIX F2600
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
Anker SOLIX F2600 costs $2200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 60% more energy (4096Wh vs 2560Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 5200W more surge headroom (8000W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX F2600 is 51.3 lb lighter (61.7 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
Anker SOLIX F2600
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
