Bluetti AC500 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 $300 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 104% more energy (3072Wh vs 1505Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 6400W more surge headroom (10000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500 is 13.3 lb lighter (52.75 lb vs 66.1 lb).
- Goal Zero Yeti 1500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Bluetti AC500
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
Where it falls short:
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
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
