Growatt INFINITY 1500 vs Ampace Andes 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
Ampace Andes 1500 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 3% more energy (1512Wh vs 1462Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 0.7 lb lighter (36.8 lb vs 37.5 lb).
Growatt INFINITY 1500
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
Ampace Andes 1500
Backed by an Amperex/CATL cell pedigree, the Andes 1500 stands out on charge speed — 0-80% in well under an hour — and a light 36.8 lb for 1.5kWh.
Best for: Buyers who prize fast charging and low weight at 1.5kWh.
Where it falls short:
- Newer brand with a thinner track record
- Not expandable
