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 $500 less. Whether that gap is worth closing depends on what you need to run.

Bluetti Apex 300

6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.

Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.

Where it falls short:

  • 79.4 lb
  • Newer product with limited long-term field data
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
