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.
WARNING: If the LED connection number is wrong, the load or controller
is damaged.
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 fuse or turn on the breaker during
the installation. When disconnecting the system, the order will be reversed.
2) After power on the controller, check the battery LED indicator on the controller, it will be
on solid green. Otherwise please refer to chapter 8.
3) 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.
Load self-test function
The load is ON when the controller power on 10seconds. After 10 seconds it will restore to
set working mode.

4)Time Control
Control the load on/off time through setting real-time clock.
5) Intelligent Power Mode
When the battery voltage is lower than “Under Voltage Warning Recover Voltage (UVWR
adjustable)”, the intelligent power mode is enabled; at this time, the LED current
percentage will be automatically reduced in linear with the voltage drop of battery. When
the battery voltage is lower than “Under Voltage Warning Voltage (UVW adjustable)”, a
minimum LED current percentage (default 2%, adjustable) will be output. In addition, when
the battery voltage is higher than UVWR, the controller will exit the intelligent power mode.
NOTE：The load is ON when the controller power on 1seconds. After 1
seconds it will restore to set working mode.
NOTE：In the mode of Light ON/OFF and Light ON/Timer, the load is
turned on after 10Min. delay，the delay time can be set.

voltage is lower than
the rated voltage, it is
not working.
①Replace the LED light
②Reduce system rated voltage grade
and replace the product model
For example 24V system change to
12V system, and replace the
corresponding controller.
①When 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.
WARNING: The LVRV can be set, but it must pay more attention that it
maybe damages the battery if the LVRV is too low.
9. Technical Specifications
◆The controller is not recognize system voltage and no temperature compensation
when the battery connect the lithium battery.
▼The parameters are 12V system at 25 ºC, please double the values in 24V system.
10. Disclaimer
This warranty does not apply under the following conditions:
Damage from improper use or use in an unsuitable environment.
PV or load current, voltage or power exceeding the rated value of controller.
The controller is working temperature exceed the limit working environment
temperature.
User disassembly or attempted repair the controller without permission.
The controller is damaged due to natural elements such as lighting.

There are two methods that it can realize controller work
mode and parameters through IR function:
1) IR Remote Controller—RC-10
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.
