Growatt INFINITY 1500 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 $800 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 406% more energy (1512Wh vs 299Wh), so it runs the same load proportionally longer.
- Growatt INFINITY 1500 has 1800W more surge headroom (3000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R600 is 24.7 lb lighter (12.8 lb vs 37.5 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 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 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
