Growatt INFINITY 1500 vs UGREEN PowerRoam 1200
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
UGREEN PowerRoam 1200 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 48% more energy (1512Wh vs 1024Wh), so it runs the same load proportionally longer.
- Growatt INFINITY 1500 has 500W more surge headroom (3000W vs 2500W) — that decides whether a fridge, pump or AC compressor will actually start.
- UGREEN PowerRoam 1200 is 11.0 lb lighter (26.5 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.
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 well-rounded 1kWh with an unusually high 1,000W solar input for its price — it recharges off panels faster than most rivals in the class.
Best for: Off-grid campers who prioritise fast solar recharging at 1kWh.
Where it falls short:
- 1,200W output trails the 1,800W class leaders
- Not expandable
