How Semi-Integrated differs from All-in-One

Adjustable panel

Solar panel mounts on a separate arm — tilt angle optimised per location for 15–20% more charging

Larger battery box

External IP67 battery box holds bigger LiFePO4 packs — enabling 4–5 night backup even with 120W LED

MPPT controller

Maximum Power Point Tracking controller is standard on all SI models — 30% more efficient than PWM

Pole separated

LED head, battery, and panel are separate units — any component can be replaced independently
