Growatt INFINITY 1500 vs Bluetti AC180P
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 AC180P costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 5% more energy (1512Wh vs 1440Wh), so it runs the same load proportionally longer.
- Growatt INFINITY 1500 has 300W more surge headroom (3000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180P is 0.5 lb lighter (37 lb vs 37.5 lb).
- Bluetti AC180P is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
A capable mid-size that flies under the radar. Solid 2,000W output and fast charging, let down mainly by a shorter warranty than the big brands.
Best for: Value hunters who want 1.5kWh and don't need the longest warranty.
Where it falls short:
- 3,000W surge is modest for the output
- 3-year warranty vs 5 from the majors
A higher-capacity take on the AC180, adding 25% more watt-hours for the same 1,800W output — a useful step up if you catch it near the AC180's price.
Best for: Buyers who want more than 1kWh from a mainstream brand on sale.
Where it falls short:
- 37 lb
- 2,700W surge is mid-pack
- Not expandable
