5. Installation and Setup
5.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and water.
- Ensure there is sufficient airflow around the controller for proper cooling.
- Mount the controller vertically on a wall or suitable surface using appropriate fasteners.
5.2 Wiring Connections
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in reverse order.
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the battery voltage (12V/24V/36V/48V).
- Connect the Solar Panel: Connect the positive and negative terminals of your solar panel array to the corresponding PV input terminals on the controller. Ensure correct polarity. The maximum open circuit voltage (Voc) from the PV array should not exceed 160V.
- Connect the DC Load (Optional): If using a DC load directly from the controller, connect its positive and negative terminals to the load terminals on the controller.

5.3 Battery Type Selection
The controller supports various battery types. You can select the appropriate type through the controller's settings menu. For lithium batteries (LiFePO4, Li(NiCoMn)O2), it is essential to set the specific start and end charging voltages according to the battery manufacturer's specifications. Refer to the detailed instructions in the user manual for proper configuration.

6. Operating Instructions
6.1 LCD Display and Buttons
The LCD display provides real-time system status. Use the buttons (PV, BAT, DC, SET) to navigate through menus and adjust parameters. Refer to the detailed manual for specific button functions and menu navigation.
6.2 Charging Stages
The controller employs a multi-stage charging algorithm to optimize battery life and performance:
- Bulk Charge: Charges the battery at maximum current until voltage rises to the absorption level.
- Constant Charging (Boost/Equalize): Maintains a constant voltage, allowing the current to gradually decrease. Equalization is a controlled overcharge for flooded batteries to balance cell voltages.
- Float Charge: Reduces the voltage to a lower level once the battery is fully charged, maintaining it at a safe level to prevent self-discharge.
6.3 Load Working Modes
The DC load output can be configured with different working modes:
- Load OFF: The load output is always off.
- Load Always ON: The load output is continuously on.
- Time Control: The load output operates for a specified duration after sunset.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller:
- Periodically inspect all wiring connections for tightness and corrosion.
- Clean the controller's exterior with a dry cloth. Do not use liquids or solvents.
- Ensure the ventilation openings are clear of dust and debris to allow for proper heat dissipation.
- Monitor the LCD display for any error codes or unusual readings.
