Bluetti AC2A vs Growatt INFINITY 1500
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 AC2A costs $900 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 641% more energy (1512Wh vs 204Wh), so it runs the same load proportionally longer.
- Growatt INFINITY 1500 has 2400W more surge headroom (3000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC2A is 29.6 lb lighter (7.9 lb vs 37.5 lb).
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.
One of the cheapest LiFePO4 stations on the market. 204Wh is tiny, but a 200W solar input that outpaces the capacity makes it a surprisingly capable little off-grid trickle unit.
Best for: Ultralight campers who recharge from a panel daily.
Where it falls short:
- 204Wh is genuinely small
- 300W output is device-only
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
