Goal Zero Yeti 1000 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 $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 53% more energy (1512Wh vs 988Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000 is 2.2 lb lighter (35.3 lb vs 37.5 lb).
- Goal Zero Yeti 1000 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000 is poor value on paper: 0.82 Wh per dollar versus 1.38 for the Growatt INFINITY 1500. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The 6th-gen Yeti 1000 finally brings a real 2,000W inverter to Goal Zero's mid-size. Now it competes on output, not just toughness.
Best for: Buyers who want Goal Zero's ruggedness with real appliance-starting output.
Where it falls short:
- 35.3 lb for under 1kWh is heavy
- Premium price against lighter rivals
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
