Growatt VITA 550 vs Allpowers R600
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
Allpowers R600 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt VITA 550 holds 80% more energy (538Wh vs 299Wh), so it runs the same load proportionally longer.
- Allpowers R600 is 4.8 lb lighter (12.8 lb vs 17.6 lb).
- Allpowers R600 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
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 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
A light, cheap 299Wh unit with a 1,200W surge — a solid budget companion for devices and the occasional small appliance.
Best for: Budget campers charging devices with occasional small-appliance use.
Where it falls short:
- 299Wh is small
- 600W continuous output
