Wiring
Reference for Serial connection of LED
Connection Order
- Connect components to the charge controller in the sequence, as shown in Figure 2 Wiring, and pay much attention to the “+” and “-.” Please don’t insert the fuse or turn on the breaker during the installation. When disconnecting the system, reverse the order.
- After powering on the controller, check the controller’s battery LED indicator; it usually is green. Otherwise, please refer to chapter 8.
- Connect a fuse in series through battery positive (+) in the circuit. The battery circuit fuse must be 1.25 to 2 times the rated current. The installed distance is within 150mm.
Load self-test function
The load is ON when the controller power on for 10 seconds. After 10 seconds, it restores the working mode setting.

- Time Control
Control the load on/off time by setting the real-time clock. - Intelligent Power Mode
When the battery voltage goes lower than the “Reduce Power Start Voltage (adjustable),” the intelligent power reduction mode is enabled. The LED output current is automatically reduced in linear with the battery’s voltage drop. When the battery voltage goes lower than the “Reduce Power End Voltage (adjustable),” the LED output current is 2% of the rated load current. The minimum percentage can be set to 1%). Also, when the battery voltage is higher than “Reduce Power Start Voltage,” the controller exits the intelligent power reduction mode.
Setting Operation
There are two methods to check and set the controller’s parameters:
- IR Remote Controller—RC-10
- Super Parameter Programmer—FC-01
This method can realize one-key setting operation which is suitable for bulk quantity products setting or applied in the projects.
NOTE: Please refer to the user manual of handheld device.

Troubleshooting
| Faults | Possible reasons | Troubleshooting |
| Charging LED indicator off during daytime when sunshine falls on PV modules properly | PV array disconnection | Confirm that PV and battery wire connections are correct and tight |
| No LED indicator | Min.9V can start up the controller. | Measure the battery voltage with a multi-meter. Min.9V can start up the controller. |
| Battery LED indicator green Fast Flashing | Battery over voltage | ①Disconnect the solar array and measure the battery voltage; ② Change the controller; ③ Change the battery |

| All the LED indicator flashing(battery red | System voltage error | Check whether the battery voltage matches the controller’s working |
| indicator flashing) | voltage. Please change to a suitable battery or reset the working voltage | |
| Powering on normally, the load is off | ①The connecting wires are error or virtual connection ②Load mode is wrong ③The controller does not match with the LED light. ④Output short circuit | ①Check the connecting cables ②Check the load mode and parameter ③The voltage of the LED light source is not in the output voltage range of the controller ④Check the connecting cables and LED light source |
| The dimming function is invalid | The controller does not match with the LED light source. This product is a step-up current control; if the input voltage is lower than the rated voltage, it is not working. | ① Relace the LED light ②Reduce system rated voltage grade, and replace the product model For example, switch the 24V system to the 12V system, and replace the corresponding controller. |
① When the battery is over discharged, the battery indicator will be red. The load will be off all the time before the voltage is more than the Low Voltage Reconnect Voltage (LVRV). To judge the system is normal or not, firstly measuring the battery voltage, whether it is more than LVRV; if not, restarting the controller to detect the load.
