4.2 Load Operating Modes
The controller offers four distinct load operating modes. The default setting is continuous load operation (24 hours). You can select the appropriate mode based on your application needs.

Figure 3: Four Load Operating Modes.
- LD1 (Regular Mode): The load operates normally and can be turned on or off manually.
- LD2 (Light Control Mode): The load automatically turns on at dusk and off at dawn.
- LD3 (Light & Time Control Mode): The load turns on at dusk and operates for a set number of hours, then turns off. It automatically identifies dark and light conditions based on the local environment.
- LD4 (Reverse Light Control Mode): The load automatically turns on at dawn and off at dusk.
4.3 Battery Type Setting
The controller supports various battery types including User default, Sealed, Flooded, GEL, LiFePo4, and Li(NiCoMn)O2. Ensure the correct battery type is selected in the controller settings to optimize charging and prevent damage to your battery. Refer to the specifications table for specific voltage parameters for each battery type.
5. Protection Functions
The ANERN AN-MSC-60A controller is equipped with multiple protection features to ensure the safety and longevity of your solar system.

Figure 4: Protection Functions.
- Solar Panel Reversed: Protection against reverse connection of the solar panel if the battery is not connected.
- Battery Reversed: Protection against reverse connection of the battery if the PV is unconnected.
- Battery Over-Voltage: Prevents battery damage when voltage reaches the over-voltage point.
- Battery Over-Discharge: Prevents battery damage when voltage drops below the under-voltage point.
- Over-Load: Protects the system if the load current exceeds the rated current.
6. Maintenance
Regular maintenance helps ensure the optimal performance and longevity of your solar charge controller.
- Cleanliness: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Connections: Periodically check all wiring connections for tightness and corrosion. Loose connections can lead to power loss or overheating.
- Ventilation: Ensure the installation area remains well-ventilated to facilitate proper heat dissipation from the controller's aluminum back cover.
- Environmental Check: Verify that the operating environment is within the specified temperature and humidity ranges.
7. Troubleshooting
If you encounter issues with your solar charge controller, refer to the following common problems and solutions:
- Controller Not Functioning / No Display:
- Check battery connections: Ensure the battery is properly connected and has sufficient voltage. The controller requires battery power to operate.
- Verify wiring: Double-check all wiring according to the diagram, paying close attention to polarity.
- Inspect fuses/breakers: Ensure any inline fuses or circuit breakers in the system are not tripped or blown.
- No Charging from Solar Panels:
- Check solar panel connections: Ensure PV array is correctly connected to the controller with proper polarity.
- Verify solar panel output: Measure the voltage and current of your solar panels to ensure they are producing power.
- Sunlight conditions: Ensure adequate sunlight is reaching the solar panels.
- Load Not Working:
- Check load connections: Ensure the load is correctly wired to the controller.
- Verify load mode: Confirm the selected load operating mode (e.g., LD1, LD2) is appropriate for your needs.
- Battery voltage: If the battery voltage is too low (below LVD), the controller will disconnect the load to protect the battery.
- Overload protection: If the load current exceeds the controller's rated discharge current, the overload protection may activate. Reduce the load.
8. User Tips
- Always connect the battery first and disconnect it last to prevent damage to the controller.
- Ensure your battery type is correctly configured in the controller settings for optimal charging and battery lifespan.
- If the controller appears non-functional, always start by checking all cable connections and the battery's state of charge.
