The short answer
Growatt INFINITY 1500 costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 0% more energy (1512Wh vs 1505Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 15.3 lb lighter (37.5 lb vs 52.75 lb).
- Goal Zero Yeti 1500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Goal Zero Yeti 1500
The new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity
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
