Growatt INFINITY 1500
1512 Wh · 2000 W output · LiFePO4 · $1099
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
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.
What we like
- 2,000W output at a competitive price
- 1.8-hour recharge
- 800W solar input
Where it falls short
- 3,000W surge is modest for the output
- 3-year warranty vs 5 from the majors
