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：Caution electricity! 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 fuse or turn on the breaker
during the installation. When disconnecting the system, the order will be reserved.
2) After powering 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 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.
4) The charging and discharging process can't be operated simultaneously, and the
discharge process should be operated before charging.
⚫Load self-test function
The load is ON when the controller power on for 10seconds. After 10 seconds, it will
restore to set working mode.

3) Light ON + Timer
Light ON + Timer1
Light ON + Timer2
Light ON + Timer3
4) Real-time Control
Control the load ON/OFF time by setting a real-time clock.
5) Intelligent Power Reduction Mode
When the battery voltage is reduced to 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 is reduced to
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 the mode of Light ON/OFF and Light ON/Timer, the load is turned on
after a 1-minute delay, the delay time can be set.
NOTE：The controller's real-time clock is an analog clock; it is valid at power-on
and invalid after power-off. When using the time mode, the clock needs to be
calibrated by handheld devices. The controller cannot be powered off after
calibration.

①The connecting wires
are error or
virtually connected
②Load mode is not
appropriate.
③This controller does not
match the LED light.
④Output short circuit.
①Check the connecting cable.
②Check the load's mode and
parameters.
③The voltage of 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 system rated voltage
grade, and replace the product
model
For example 24V system change to
a 12V system and replace the
corresponding controller
①After the battery is over-discharged, the battery indicator is red. And the load is turned
off all the time until the voltage reaches the Low Voltage Reconnect Voltage (LVRV). To
judge the system is normal or not, firstly measuring whether the battery voltage is higher
than LVRV. If not, restarting the controller to detect whether the load output is normal.
NOTE: The LVRV can be set, but it must pay more attention to modification. Too
low LVLR may damage the battery.

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 exceeds the controller's rated value.
The controller's working temperature exceeds the limit working environment
temperature.
User disassembly or attempted to repair the controller without permission.
The controller is damaged due to natural elements such as lighting.
The controller is damaged during transportation and shipment.
