Wiring
- 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 one LED (1W, 3.3V) is calculated. If the user uses the
unconventional LED, The actual LED voltage must less than the Max. Load
Output Voltage.
WARNING：DO NOT electric shock! The product built-in boost LED driver, the
output voltage is higher than the human safety voltage.
Connection Order
- Connect components to the charge controller in the sequence as shown above 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, the order will be reserved.
- After power 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.
- Connecting a fuse in series through battery positive (+) in the circuit and the battery circuit fuse must be 1.25 to 2 times to the rated current. The installed distance is within 150mm.
NOET: The controller can only charge or discharge alone, but it can carry out the discharge process to check the load preferentially.
Load self-test function
The load is ON when the controller power on 10seconds. After 10 seconds it
will restore to set working mode.

Load Working Mode
- Manual Mode
- Light ON/OFF(Default)
- Real-time Control
Control the load ON/OFF time through setting real-time clock. - 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 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.
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.
Setting Operation
There are three methods that it can realize controller load modes and parameters through IR function:
-
IR Remote Control—RC10
-
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. -
Mobile APP+eBox-WIFI&IR-01/02 Real-time monitoring and setting the parameters
Note: Please refer to the user manual of handheld device
Protection

Troubleshooting
| Faults | Possible reasons | 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 maybe 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 battery voltage
is higher than OVD, and disconnect the PV
Battery LED indicator red| Battery
over discharged| When the battery voltage is restored to or above 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 decline to be
below 50 °C, the controller will resume.
Powering on normally, the load is off| GThe connecting
wires are error or virtually connected ”)Load mode is not appropriate.
‘ 3)This controller does not match with the LED light.
‘i)Output short circuit.| ‘0 Check the connecting cable. (2) Check the load’s
mode and parameters.
The voltage of LED light is not X
within the output voltage range of controller.
(4)Check the connecting cables and LED light.
The dimming function is invalid| The controller does not match with the LED
light source. This product is a step-up voltage control, If input voltage is
lower than the rated voltage, it is not working.| GReplace the LED light
‘-)Reducesystem rated voltage grade and replace the product model
For example 24V system change to 12V system, and replace the corresponding
controller
Parameter settings fail| Infrared communication error| Refer to handheld the
user device manual
- When the battery is over discharged, the battery indicator will be red and the load will be off all the time before the voltage is more than the Low Voltage Reconnect Voltage (LVRV). In order to judge the system is normal or not, firstly measuring the battery voltage whether is more than LVRV, if not, restarting the controller to detect the load whether it is normal. NOTE: The LVRV can be set, but it must pay more attention that it maybe damages the battery if the LVRV is too low.
