Growatt INFINITY 1500 vs Segway Cube 1000
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
Segway Cube 1000 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.
- Segway Cube 1000 has 1400W more surge headroom (4400W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Segway Cube 1000 is 9.1 lb lighter (28.4 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
Segway Cube 1000
Segway's stackable home unit brings a strong 2,200W output at 1kWh and a modular design, though the cube form factor is bulkier than flat rivals.
Best for: Buyers who want a stackable, expandable home system starting at 1kWh.
Where it falls short:
- Bulky cube shape
- 3-year warranty
