Goal Zero Yeti 1000 vs Fossibot F2400
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
Fossibot F2400 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Fossibot F2400 holds 107% more energy (2048Wh vs 988Wh), so it runs the same load proportionally longer.
- Fossibot F2400 has 1200W more surge headroom (4800W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000 is 13.2 lb lighter (35.3 lb vs 48.5 lb).
- Goal Zero Yeti 1000 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000 is poor value on paper: 0.82 Wh per dollar versus 2.28 for the Fossibot F2400. 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 value-brand 2kWh that undercuts the majors sharply while matching them on the specs that matter — 2,400W output and a strong 4,800W surge.
Best for: Bargain hunters who want high surge and 2kWh for the least money.
Where it falls short:
- 500W solar input is low for 2kWh
- Support network trails the majors
