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
Goal Zero Yeti 1500 costs $2000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 172% more energy (4096Wh vs 1505Wh), 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.
- Goal Zero Yeti 1500 is 60.3 lb lighter (52.75 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
Goal Zero Yeti 1500
The new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity
