Bluetti AC500 vs Goal Zero Yeti 700
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 700 costs $1200 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 354% more energy (3072Wh vs 677Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 9000W more surge headroom (10000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 45.8 lb lighter (20.3 lb vs 66.1 lb).
- Goal Zero Yeti 700 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 700
The largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
Where it falls short:
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
