5. Installation Guide
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully:
5.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure sufficient clearance around the controller for proper airflow, especially around the cooling vents.
- Mount the controller vertically on a non-flammable surface using appropriate fasteners.
5.2 Wiring Connections
Connect the components in the following order: Battery > Solar Panel > Load. Always ensure correct polarity.
- Connect the Battery: Connect the battery cables to the battery terminals on the controller. Ensure the positive (+) and negative (-) terminals are correctly matched. The controller will automatically detect the battery voltage (12V or 24V).
- Connect the Solar Panel: Connect the solar panel cables to the PV input terminals on the controller. Verify correct polarity. Ensure the open circuit voltage (Voc) of your solar array does not exceed 100VDC.
- Connect the Load: Connect your DC load to the load output terminals. Ensure the load current does not exceed the controller's rated load current.
- Connect Temperature Sensor: Plug the remote temperature sensor into its designated port. This sensor helps the controller optimize charging based on battery temperature.
The controller is compatible with various battery types:

6. Operation Guide
Once installed, the controller will begin operation. The LCD display provides real-time system status and allows for configuration.
6.1 LCD Display
The backlit LCD display shows various parameters such as battery voltage, charging current, solar panel voltage, load status, and accumulated energy (KWH). Use the buttons below the display to navigate through the different screens and access settings.
6.2 Basic Settings
The controller allows users to set parameters for different battery types (Lithium, LiFePO4, Li(NiCoMn)O2, Flooded, Sealed, Gel). Refer to the on-screen menu for specific adjustments to absorption voltage, float voltage, and low voltage disconnect settings. A load timer function is also available for controlling DC loads.
6.3 Cooling Fan Operation
The built-in cooling fan activates automatically when the internal temperature exceeds 45°C (113°F) and turns off when the temperature drops below 40°C (104°F). This mechanism ensures optimal performance and extends the lifespan of the controller.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your solar charge controller.
- Cleaning: Periodically clean the controller's exterior with a dry cloth. Ensure cooling vents are free from dust and debris.
- Connections: Annually inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and damage.
- Environment: Verify that the installation environment remains dry and well-ventilated.
