※The default value can be changed according to the user's requirement.
4)Time Control
Control the load on/off time by setting the 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 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.
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.
The controller's real-time clock is an analog clock, valid at power-on and
invalid after power-off. When using the time mode, the clock needs to be
calibrated by handheld devices. Do not power off the controller after
calibration.

7. Protection
When the battery is correctly connecting, the
PV can be reversed.
The controller is no
damage
When the PV is not connected, or the
connection reversed, the battery can be
reversed.
WARNING: Controller is damaged when
the PV connection is correct, and the
battery connection is reversed!

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

This product is a
step-up current
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 replaced the product model
For example, switch the 24V system to a
12V system, and replace the
corresponding controller.
①When the battery is over-discharged, the battery indicator is red. The load keeps 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.
The LVRV can be set, but it must be done carefully to avoid damaging the
battery if the LVRV is set too low.
9. Technical Specifications
◆When selecting a lithium battery, the controller cannot automatically recognize
the nominal system voltage and has no temperature compensation.
▼The parameters are the 12V system at 25 ºC, double the values in the 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 exceeds the rated value of the controller.
The controller's working temperature exceeds the limit working 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 or shipment.
