Operating Instructions
Charging Process and Indicators
Once the solar panel is properly connected and exposed to sunlight, it will begin charging your 12V battery. The built-in controller manages the charging process to prevent overcharging and battery drain.
- Sunlight Detection: The solar panel features a red indicator light that illuminates when sufficient sunlight is detected and the panel is generating power.
- Charging Status: A green indicator light will illuminate when the battery is actively being charged. When the battery reaches full capacity, the controller will automatically stop charging, and the green light may turn off or change behavior depending on the charge state. Charging will resume automatically if the battery voltage drops.
- Stable Output: The amorphous material of the solar panel allows it to provide a stable output even in cloudy or low-light conditions, ensuring continuous battery maintenance.
