Anker SOLIX F3800 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
Bluetti AC500 costs $2000 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 25% more energy (3840Wh vs 3072Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 1000W more surge headroom (10000W vs 9000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC500 is 66.2 lb lighter (66.1 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
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
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
