Goal Zero Yeti 500 vs Bluetti AC500
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 500 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 516% more energy (3072Wh vs 499Wh), 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 500 is 53.2 lb lighter (12.9 lb vs 66.1 lb).
- Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Goal Zero Yeti 500
A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.
Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.
Where it falls short:
- $699 for 499Wh is expensive per watt-hour
- Only a 2-year warranty vs 5 years from most rivals
- 120W solar input is very low
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
