Solar recharge
The SOLIX C1000 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: Anker SOLIX 531 (200 W) · Renogy 200W Rigid (MC4) (200 W) · Rich Solar 400W Kit (MC4) (400 W).
