6. Operating Instructions

Once properly installed, the controller will automatically begin charging the battery from the solar panels. The built-in display provides real-time information on system status.

• Display Indicators: The controller features indicators for battery status and charging. Refer to the specific markings on the device for detailed interpretation.
• Parameter Adjustment: Use the "SET" button to navigate through various parameters and the "COM" button (or similar) to adjust values. This allows for fine-tuning charging settings to match your battery type and requirements.
• Load Control: If a DC load is connected, the controller can manage its operation based on battery voltage or programmed timers.

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your solar charge controller:

• Cleaning: Periodically clean the controller's exterior with a dry cloth to remove dust and debris. Ensure the heat sink fins are clear of obstructions.
• Connection Check: Annually inspect all wiring connections for tightness and signs of corrosion. Re-tighten if necessary.
• Environmental Check: Ensure the installation environment remains within the specified operating temperature range (-35℃ to +45℃) and is free from excessive humidity.
