5. Operating Instructions
Once connected and exposed to sunlight, the solar charger will automatically begin charging your 12V battery. The built-in MPPT controller optimizes the charging process.
5.1. LED Indicator Lights
The solar panel features three LED indicator lights to show its operational status:
- Blue Light: Indicates that the solar panel is receiving sufficient sunlight.
- Red Light: Indicates that the battery is currently charging.
- Green Light: Indicates that the battery is fully charged and the charger is in maintenance mode.
- No Lights: May indicate a short circuit or insufficient sunlight.

The controller will automatically shut off at night or when not generating power to prevent draining the battery. It will resume charging the next day when sunlight is available.
6. Maintenance
- Cleaning: Regularly clean the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris. Do not use harsh chemicals or abrasive materials.
- Inspection: Periodically check all connections (alligator clips, O-ring terminals, cigarette lighter plug) to ensure they are secure and free from corrosion.
- Storage: When not in use for extended periods, store the solar panel in a dry, safe place away from direct sunlight and extreme temperatures.
