Growatt INFINITY 1500 vs Goal Zero Yeti 1000X
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 $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 54% more energy (1512Wh vs 983Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X is 5.8 lb lighter (31.68 lb vs 37.5 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.
We'd skip the Goal Zero Yeti 1000X in this matchup. It costs $100 more than the Growatt INFINITY 1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
