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 VITA 550 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Segway Cube 1000 holds 90% more energy (1024Wh vs 538Wh), so it runs the same load proportionally longer.
- Segway Cube 1000 has 3200W more surge headroom (4400W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt VITA 550 is 10.8 lb lighter (17.6 lb vs 28.4 lb).
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
Growatt VITA 550
A tidy half-kWh unit with fast charging and a 1,200W surge that lets it start small appliances a 600W rating wouldn't suggest.
Best for: Campers who want fast charging and a bit of surge headroom at half a kWh.
Where it falls short:
- 538Wh is weekend-scale
- 3-year warranty
