Goal Zero Yeti 300 vs Growatt VITA 550
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
Goal Zero Yeti 300 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt VITA 550 holds 81% more energy (538Wh vs 297Wh), so it runs the same load proportionally longer.
- Growatt VITA 550 has 600W more surge headroom (1200W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 3.9 lb lighter (13.7 lb vs 17.6 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
Where it falls short:
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
A tidy half-kWh unit with fast charging and a 1,200W surge that lets it start small appliances a 600W rating wouldn't suggest.
Best for: Campers who want fast charging and a bit of surge headroom at half a kWh.
Where it falls short:
- 538Wh is weekend-scale
- 3-year warranty
