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
Growatt INFINITY 1500 costs $200 less. Whether that gap is worth closing depends on what you need to run.
- UGREEN PowerRoam 2000 holds 35% more energy (2048Wh vs 1512Wh), so it runs the same load proportionally longer.
- UGREEN PowerRoam 2000 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 17.5 lb lighter (37.5 lb vs 55 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
UGREEN PowerRoam 2000
UGREEN's 2kWh option covers full-day home backup at a competitive price, though it isn't expandable like the majors' modular systems.
Best for: Buyers who want a self-contained 2kWh backup without building a modular system.
Where it falls short:
- 55 lb
- Not expandable
