4. Setup
Installation Location:
Mount the controller vertically on a wall or sturdy surface. Ensure there is ample space around the controller for proper heat dissipation. Avoid direct sunlight, high temperatures, and humid environments.
Wiring Diagram:
Follow the wiring diagram carefully. Incorrect wiring can damage the controller and other components.
Figure 4.1: Schematic of Wiring Diagram.
Wiring Steps:
- Mount the Controller: Securely mount the controller to a wall using screws. Ensure controllers are at the same horizontal level with ample space for heat dissipation between devices.
- Remove Port Cover: Carefully remove the terminal cover from the bottom of the controller.
- Connect Battery Cables: Connect the positive (+) and negative (-) battery cables to the corresponding terminals on the controller. Ensure the battery circuit breaker is open before connecting.
- Connect Solar Panel Cables: Connect the positive (+) and negative (-) solar panel cables to the corresponding PV input terminals. Ensure the solar circuit breaker is open before connecting.
- Connect Load Cables (Optional): If using the load output, connect the positive (+) and negative (-) load cables to the load terminals.
- Install Port Cover: Replace the terminal cover.
- Power On: First, close the battery circuit breaker. Then, close the solar circuit breaker. The controller display should power on.
CAUTION: While wiring, ensure the circuit breaker or fuse is closed and that the leads of "+" and "-" poles are connected correctly. A fuse with a current 1.25 to 2 times the rated current of the controller must be installed on the battery side with a distance from the battery not greater than 150 mm. If the controller is to be used in an area with frequent lightning strikes or unattended areas, an external surge arrester must be installed. If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the load side of the controller.
Parallel Communication Setup (for multiple controllers):
If using multiple controllers in parallel, they can communicate to synchronize settings. Assemble the parallel communication cable by connecting red and black wires to the green terminal blocks as shown in the diagram. Connect these cables to the RS485 communication ports on each controller.

After connecting the parallel communication cable, power on the controllers by closing the battery circuit breaker first. Set a unique parallel code for each controller. The device with the smallest code becomes the main controller, and other controllers will automatically synchronize their configurations with the main controller.
5. Operating Instructions
LCD Display and Buttons:
The controller features an LCD display and multiple buttons for navigation and settings adjustment.
Figure 5.1: Examples of various display settings.
Setting Battery Type:
The controller is compatible with Sealed, Gel, Flooded, and User-defined (LiFePO4) battery types. To set the battery type:
- Press and hold the 'PV/SET' button to enter the setup program.
- Navigate through the settings using the 'BAT+' and 'BAT-' buttons.
- Select the desired battery type (SEL for Sealed, GEL for Gel, FLD for Flooded, USE for User-defined).
- For LiFePO4 batteries, select 'USE' and manually enter the specific parameters as per your battery manufacturer's recommendations.
- Press and hold 'PV/SET' again to save the settings and exit.
Monitoring Parameters:
The LCD display shows various parameters such as PV voltage, battery voltage, charging current, load current, and temperature. Use the navigation buttons to cycle through these displays.
Load Control:
The controller supports multiple load control methods. Refer to the detailed operating manual for specific programming of load timers and modes.
6. Maintenance
- Regular Inspection: Periodically check all wiring connections for tightness and corrosion.
- Cleaning: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
