Bluetti AC500 vs Anker SOLIX F2600
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
Anker SOLIX F2600 costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 20% more energy (3072Wh vs 2560Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 7200W more surge headroom (10000W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX F2600 is 4.4 lb lighter (61.7 lb vs 66.1 lb).
- Anker SOLIX F2600 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
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
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
