Installation

Unpack and inspect contents. Ensure all components are present and undamaged.

Choose Location: Place panel in direct sunlight, free from shadows.
Set Angle: Use kickstand to adjust panel angle towards the sun (approx. 30-45 degrees).
Connect to Battery: Attach alligator clips to battery terminals (RED to positive, BLACK to negative).
Connect to Device: Plug USB cable into USB port for USB devices, or use DC connector for 12V devices.

WARNING! Do not look directly at the sun or panel surface. Avoid placing near heat sources or flammable materials. Ensure secure connections to prevent sparks.

First-Time Setup

Position panel and connect to battery or device for initial use.

Fully unfold panel and extend kickstand on a stable, flat surface.
Orient panel towards the sun for maximum exposure.
Connect alligator clips to 12V battery, observing correct polarity.
Check indicator lights: Green LED indicates charging/power flow.
For USB devices: Connect USB cable from panel to device.

CAUTION! Never short-circuit the panel outputs. Disconnect when not in use. Keep panel surface clean and dry.
