Goal Zero Yeti 3000X vs Growatt INFINITY 1500
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 $2100 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 101% more energy (3032Wh vs 1512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 500W more surge headroom (3500W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 32.3 lb lighter (37.5 lb vs 69.75 lb).
- Growatt INFINITY 1500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Growatt INFINITY 1500 is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 3000X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
A large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
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
