Bluetti AC500 vs Bluetti Apex 300
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 Apex 300 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 11% more energy (3072Wh vs 2764Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 2320W more surge headroom (10000W vs 7680W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC500 is 13.3 lb lighter (66.1 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 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
Bluetti Apex 300
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
