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.

Protection

Protection	Conditions	Status
PV Reverse Polarity	When the battery is correctly connecting,

the PV can be reversed.

| **** The controller is no damage
**** Battery Reverse Polarity| When the PV is not connected, or the connection is reversed, the battery can be reversed.

WARNING: Controller is damaged when the PV connection is correct, and the

battery connection is reversed!

Battery Over Voltage| The battery voltage reaches the OVD| Stop charging
Battery Over Discharge| The battery voltage reaches the LVD| Stop discharging
Battery Overheating| The temperature sensor is higher than 65℃| Output is OFF
The temperature sensor is less than 55℃| Output is ON
Li-battery Low Temperature ★| The temperature sensor is less than the low-temperature value| Stop charging or discharge
The temperature sensor is higher than the low-temperature value| Begin charging or discharge
**** Load Short Circuit| Load current ≥2.5 times rated current

In one short circuit, the output is OFF 5s; Two short circuits, the output is OFF 10s; Three short circuits, the output is OFF 15s; Four short circuits, the output is OFF 20s; Five short circuits, the output is OFF 25s; Six short circuits, the output is OFF

| Output is OFF Clear the fault: Restart the controller or wait for one night-day cycle (night time>3

hours).

Load Open Circuit(Load over voltage)| Max. load voltage≥68V One open circuit, the output is OFF 5s; Two open circuits, the output is OFF 10s; Three open circuits, the output is OFF 15s; Four open circuits, the output is OFF 20s; Five open circuits, the output is OFF 25s; Six open circuits, the output is OFF 5s; Seven open circuits, the output is OFF 5s| Output is OFF (Cycle to perform)

If selecting a lithium battery, set the low-temperature value(LTV) according to the specification; otherwise, the lithium battery is damaged.

Troubleshooting

Faults	Possible reasons	Troubleshooting

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.

---|---|---
**** 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.
