5. Setup and Installation
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 suitable indoor location that is dry, well-ventilated, and protected from direct sunlight, high temperatures, and moisture.
- Ensure there is sufficient space around the controller for air circulation, especially for the cooling fan.
- Use the provided brackets and screws to securely mount the controller to a vertical surface.
5.2 Wiring Connections
WARNING: Always connect the battery first, then the solar panel. Disconnect in reverse order: solar panel first, then battery. Incorrect connection order can damage the controller.
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the corresponding battery terminals on the charge controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V, 24V, or 48V).
- Connect the Solar Panels (PV Array): Connect the positive and negative leads from your solar panel array to the PV input terminals on the charge controller. Ensure correct polarity.
- Verify that the open-circuit voltage (Voc) of your PV array is within the specified range for your system voltage:
- 12V system: DC20V~DC150V
- 24V system: DC37V~DC150V
- 48V system: DC72V~DC160V
- The maximum PV module open circuit voltage should not exceed 150V for 12V/24V batteries or 160V for 48V batteries. Exceeding 180V will damage the controller.
- For optimal efficiency, aim for a PV Voc that is 1.5 to 2 times your battery voltage.
- Verify that the open-circuit voltage (Voc) of your PV array is within the specified range for your system voltage:
- Connect the Load (Optional): If your controller has load terminals, connect your DC loads to these terminals. Ensure the total current of the loads does not exceed the controller's rated load current.

6. Operation
6.1 Initial Power-Up
Once all connections are secure and correct, the controller will power on. The LCD display will show system information. The controller will automatically recognize the system voltage (12V/24V/48V).
6.2 Charging Process
The controller utilizes a 3-stage smart MPPT charging process to optimize battery charging and prolong battery life:
- Constant Current (MPPT): In this stage, the controller tracks the maximum power point of the solar panels to deliver the maximum possible current to the battery.
- Constant Voltage (Absorption Voltage): Once the battery reaches a certain voltage, the controller maintains a constant voltage while the current gradually decreases.
- Floating Charge: After the battery is fully charged, the controller reduces the voltage to a lower "float" level to maintain the battery at full charge without overcharging.
