Anker SOLIX F3800 vs Goal Zero Yeti 1500
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 $2300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 155% more energy (3840Wh vs 1505Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 5400W more surge headroom (9000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500 is 79.6 lb lighter (52.75 lb vs 132.3 lb).
Anker SOLIX F3800
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
Where it falls short:
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
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
