Setup and Installation
Proper installation is crucial for the performance and longevity of your solar charge controller. Follow these steps carefully:
- Prepare Wiring: Ensure all wires are correctly sized for your system's current and voltage. Strip insulation approximately 8-10mm from wire ends.
- Connect Battery: Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The LCD will light up.
- Connect Solar Panel: Connect the solar panel to the controller's solar panel terminals (marked with a solar panel symbol). Ensure correct polarity.
- Connect Load: Connect the DC load to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.
- Mount Controller: Mount the controller in a well-ventilated area, away from direct sunlight and moisture.

Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
For 12V systems, use 18V solar panels. For 24V systems, use 36V solar panels.
Operating Instructions
LCD Display
The LCD screen provides real-time information about your solar system. It displays:
- Battery voltage
- Solar panel charging current
- Load discharging current
- Battery charge status
- Temperature
- Load working mode (e.g., timer setting)
Button Functions
- Menu Button: Press to cycle through display modes and enter/exit setting menus.
- Up Button (+): Used to increase values or navigate options in setting menus.
- Down Button (-): Used to decrease values or navigate options in setting menus.
- Load Control Button (Light Bulb Symbol): Toggles the DC load output on/off manually.
Parameter Settings
To adjust charging and discharging parameters:
- Press and hold the Menu button for 5 seconds to enter the setting mode.
- Use the Up (+) and Down (-) buttons to navigate through different parameters (e.g., charge voltage, discharge cut-off voltage, load timer).
- Press the Menu button once to select a parameter for adjustment. The value will flash.
- Use the Up (+) and Down (-) buttons to change the value.
- Press the Menu button again to confirm the new value.
- Press and hold the Menu button for 5 seconds to exit the setting mode.
The controller has a power-off memory function, retaining your settings even after power loss.
Dual USB Output

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your solar charge controller:
- Cleaning: Periodically clean the controller's exterior with a dry cloth to remove dust and dirt. Do not use liquids or abrasive cleaners.
- Connection Check: Annually inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause voltage drops and overheating.
- Ventilation: Ensure that the area around the controller remains clear and well-ventilated to prevent heat buildup.
- Environmental Check: Verify that the controller is not exposed to extreme temperatures, direct sunlight, or excessive moisture.
Troubleshooting
This section addresses common issues you might encounter with your solar charge controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| LCD display is off | Battery not connected or low voltage. | Check battery connections and battery voltage. Ensure battery is charged above minimum operating voltage. |
| No charging from solar panel | Solar panel not connected, incorrect polarity, insufficient sunlight, or damaged panel. | Check solar panel connections and polarity. Ensure adequate sunlight. Inspect solar panel for damage. |
| Load not working | Load not connected, incorrect polarity, load output disabled, or battery voltage too low. | Check load connections and polarity. Ensure load output is enabled (manual button or timer setting). Charge battery. |
| Overheating | Poor ventilation, excessive load, or high ambient temperature. | Ensure proper airflow around the controller. Reduce load if possible. Relocate controller to a cooler environment. |
| USB ports not charging | Device not compatible, cable issue, or controller fault. | Try a different USB cable and device. Ensure the controller is powered. |
