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 $300 less. Whether that gap is worth closing depends on what you need to run.
- Dabbsson DBS2300 holds 54% more energy (2330Wh vs 1512Wh), so it runs the same load proportionally longer.
- Dabbsson DBS2300 has 1400W more surge headroom (4400W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 16.8 lb lighter (37.5 lb vs 54.3 lb).
- Dabbsson DBS2300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
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
Dabbsson DBS2300
An expandable 2.3kWh with an unusually large base capacity for its price, and a huge expansion ceiling via Dabbsson's add-on batteries.
Best for: Buyers planning a large expandable system on a budget.
Where it falls short:
- Smaller brand and support network
- 54.3 lb
