Setup and Installation
Follow these steps for proper installation of the solar charge controller:
1. Select Installation Location and Mount Controller
Choose a suitable location for the controller. Avoid direct sunlight, high temperatures, and areas prone to water exposure. Ensure good ventilation around the controller to facilitate heat dissipation. Once the location is chosen, place the controller in position, mark the four installation holes, drill them, and then secure the controller firmly with screws.

This image illustrates the three key steps for physical installation: selecting a suitable location, marking and drilling screw holes, and finally securing the controller to the mounting surface.
2. System Connection Diagram
Refer to the diagram below for the correct wiring sequence. It is crucial to connect components in the specified order to prevent damage. Always connect the battery first, then the solar panels, and finally the load. Ensure all connections are tight and correct polarity is observed.

This diagram illustrates the complete system connection, including solar panels, the charge controller, battery bank, an inverter for AC output, and various AC/DC loads such as laptops, lights, air conditioners, televisions, and fans. Follow the arrows for power flow direction.
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the corresponding battery terminals on the controller.
- Connect Solar Panels: Connect the positive and negative terminals of your solar panel array to the corresponding PV terminals on the controller.
- Connect 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.
- Connect Inverter (Optional): If using an inverter for AC loads, connect it to the battery bank terminals, not directly to the controller's load terminals.
CRITICAL WARNING: Always connect the battery first, then the solar panel. Disconnect in the reverse order: first the load, then the solar panel, and finally the battery. Incorrect connection order can damage the controller.
Operating Instructions
LCD Display and Main Interface
The controller features a large LCD display that provides real-time operational data. The main interface displays information such as solar panel status, charging indication, battery status, load status, battery percentage, and system voltage.

This image details the LCD display, showing icons for daytime/night instructions, solar panel indication, charging indication, battery indicator, discharge indication, load indication, battery percentage, unit instruction, parameter indication, set instructions, load timing indication, error indication, battery type, and system voltage. It also shows examples of system setting parameters and power parameters.
Navigation and Settings
Use the "ESC", "UP", "DOWN", and "SET" buttons to navigate through the display and adjust parameters. The display automatically switches between different data views every 5 seconds.

This image provides a clear view of the controller's LCD screen and the "ESC", "UP", "DOWN", and "SET" buttons, highlighting the intuitive control interface.
Battery Type Selection
The controller supports various battery types. For sealed lead-acid, vented gel batteries, the parameters are automatically adjusted. For lithium batteries, you need to manually adjust the parameters according to the actual voltage of the batteries.

This diagram illustrates the controller's compatibility with various battery types, including GEL, SLD (Sealed Lead-Acid), FLD (Flooded), USR (User-defined), and Lithium batteries. A note emphasizes that while lead-acid and gel batteries are automatically adjusted, lithium batteries require manual parameter adjustment.
- GEL: Gel batteries.
- SLD: Sealed Lead-Acid batteries.
- FLD: Flooded (Open) batteries.
- USR: User-defined settings for specific battery types.
- LI: Lithium batteries (ternary lithium, lithium iron phosphate).
To change battery type or adjust parameters, press the "SET" button to enter the settings menu, then use "UP" and "DOWN" to navigate and "SET" to confirm.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Inspect Connections: Periodically check all wiring connections for tightness and corrosion. Re-tighten if necessary.
- Clean Controller: Keep the controller clean and free from dust and debris. Use a dry cloth to wipe the exterior. Ensure ventilation openings are not blocked.
- Check Battery Status: Monitor battery voltage and health regularly. Ensure batteries are properly maintained according to their manufacturer's guidelines.
- Environmental Check: Ensure the installation environment remains within recommended temperature and humidity ranges.
Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller display is off | No power from battery or solar panel; loose connections. | Check battery and solar panel connections. Ensure battery voltage is above minimum operating voltage. |
| Battery not charging | Solar panel not connected; insufficient sunlight; faulty solar panel; incorrect battery settings. | Verify solar panel connections. Check for shading. Test solar panel output. Confirm correct battery type and parameters are set. |
| Load not working | Load disconnected; over-discharge protection active; faulty load. | Check load connections. Ensure battery voltage is above the low voltage disconnect setting. Test the load directly. |
| Overheating warning | Poor ventilation; high ambient temperature; excessive load. | Ensure adequate airflow around the controller. Reduce load if possible. Relocate controller to a cooler area. |
