What it actually runs
Usable energy ≈ 847 Wh after our standard 85% inverter-efficiency assumption. Methodology

Solar recharge
The Yeti 1000X accepts up to 600 W of solar input — panels beyond that sit idle. To sustain an essentials load (~1,680 Wh/day) off-grid you'd need roughly 470 W of panels, within this unit’s cap — sun permitting, it can run essentials indefinitely.
Compatible kits: Goal Zero Boulder 200 (200 W) — proprietary connector; third-party MC4 panels need an adapter.
