• Reference for Serial connection of LED

System Voltage

| Serial connection| Min. Output Voltage| Max. Output Voltage
---|---|---|---
12V| 5~18 LED| 15V|

60V

24V

| 10~18 LED| 30V|

60V

NOTE: The above LED (1W, 3.3V) is calculated. If the user uses the unconventional LED, The actual LED voltage must be less than the Max. Load Output Voltage.

WARNING: Risk of electric shock! With the product’s built-in boost LED driver, the output voltage is higher than the human safety voltage.

• Connection Order

1. Connect components to the charge controller in the sequence as shown above and pay much attention to the “+” and “-.” Please don’t insert the fast-acting fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reserved.
2. After powering on the controller, check the battery LED indicator on the controller; it will be green. If it’s not green, please refer to chapter 9.
3. Connecting a fast-acting fuse in series through battery positive (+) in the circuit and the battery circuit fast-acting fuse must be 1.25 to 2 times the rated current. The installed distance is within 150mm.

NOTE: The controller can only charge or discharge alone but can carry out the discharge process to check the load preferentially.

• Load self-test function

The load is ON when the controller is powered on for 10 seconds. After 10 seconds, it restores to set working mode.

5. LED Indicators

Green

| Slowly Flashing(1Hz)| Full

Green

| Fast Flashing(4Hz)| Overvoltage

Orange

| On Solid| Under voltage

※ When the battery type is a lithium battery, the controller cannot recognize the system voltage automatically.

6. Load Working Mode

1. Manual Mode
2. Light ON/OFF(Default)

Turn-On voltage (Adjustable):
5V (12Vsystem), delay10min.
Turn-Off voltage (Adjustable):
6V (12Vsystem), delay10min.
Note: 24V system voltage×2

3. Light ON + Timer
   Light ON + Timer1

Light ON + Timer2

Light ON + Timer3

4. Real-time Control
   Control the load ON/OFF by setting a real-time clock.
5. Intelligent Power Reduction 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 linearly 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 exceeds “Reduce Power Start Voltage,” the controller exits the intelligent power reduction mode.

NOTE: In Light ON/OFF and Light ON/Timer mode, the load is turned on after a 1-minute delay (the delay time can be set).

7. Setting Operation

(1)          (2)           (3)

RC-10      FC-01      APP

There are three methods that it can realize controller load modes and parameters through IR function:

1. IR Remote Control – RC10
2. 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.
3. Mobile APP+eBox-WIFI&IR-01/02
   Real-time monitoring and setting the parameters

Note: Please refer to the user manual of handheld device

8. Protection

✓ Only the PV connects with the controller;
✓ The battery is positively connected, and the open-circuit voltage of the PV is lower than 85V (This requirement is only for Tracer26/39/5210LPLI).| The controller is not damaged
Battery Reverse Polarity| The battery can be reversed when the PV is not connecting or the connection is reversed.
WARNING: The controller will be damaged when the PV connection is correct while 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
Lithium battery Low Temperature (Default 35℃)| The temperature sensor is less than the low-temperature value| Lithium battery stops charging
The temperature sensor is higher than the low-temperature value| Lithium battery charging
Lithium battery limit current in low temperature| Limit current temperature
T1＞T2＞T3＞T4＞T5＞T6
Limit current I1＞I2＞I3＞I4＞I5＞I6| When the temperature is lower than T1, the charging current is I1; when the temperature is lower than T2, the charging current is I2, and so on. However, when the temperature rises gradually from T4 to T1, it is performed at I4.
Load Short Circuit| Load current ≥2.5 times rated current
First short circuit, the output is OFF 5s.
Second short circuit, the output is OFF 10s.
Third short circuit, the output is OFF 15s.
Fourth short circuit, the output is OFF 20s.
Fifth short circuit, the output is OFF 25s.
Sixth short circuit, the output is OFF.| Output is OFF
Clear the fault: Restart the controller or wait for one night-day cycle (night time>3 hours).

9. Troubleshooting

LED charging indicator turn 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| Battery voltage may be less than 8.5V| Measure battery voltage with the multi-meter. Min.8.5V can start up the controller
Battery LED indicator green fast Flashing| Battery over voltage| Check if the battery voltage is higher than OVD, and disconnect the PV
Battery LED indicator red| Battery over discharged ①| When the battery voltage is restored to or above the LVR point (low voltage reconnect voltage), the load will recover
Battery LED indicator red Flashing| Battery Overheating| The controller will automatically turn the system off. But while the temperature declines below 50ºC, the controller resumes.
Powering on normally, the load is off| ①The connecting wires are error or virtually connected
②Load mode is not appropriate.
③This controller does not match the LED light.
④Output short circuit.| ① Check the connecting cable.
② Check the load’s mode and parameters.
③The voltage of the LED light is not within the output voltage range of the controller.
④Check the connecting cables and LED light.
The dimming function is invalid| The controller does not match the LED light source. This product is step-up voltage control. If the input voltage is lower than the rated voltage, it is not working.| ①Replace the LED light
②Reduce the rated voltage grade and replace the product model For example, changes the 24V system to a 12V system and replace the corresponding controller

① After the battery is over-discharged, the battery indicator is still red, and the load is off all the time until the voltage is lower than the Low Voltage Reconnect Voltage (LVR). To judge whether the system is normal or not, firstly, measure whether the battery voltage is higher than the LVR; if not, restart the controller to detect whether the load is normal.

NOTE: The LVR can be set, but you must pay more attention to modifying it. Or, the battery may be damaged if the LVR is too low.
