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 $600 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2000 holds 35% more energy (2048Wh vs 1512Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2000 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 10.5 lb lighter (37.5 lb vs 48 lb).
Anker SOLIX F2000
The older F-series unit, now hard to justify: the C2000 offers the same capacity and surge for $400 less.
Best for: Only worth it if you find it steeply discounted below the C2000.
Where it falls short:
- $1699 is $400 over the newer C2000 with identical core specs
- 105-minute recharge is slow by 2026 standards
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
