4) Time Control
Control the load on/off time by setting the real-time clock.
5) Intelligent Power 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.
CAUTION
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.
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.

grade, and replace the product model
For example, switch the 24V system
to the 12V system, and replace the
corresponding controller.
①
When the battery is over discharged, the battery indicator will be red. The load will be 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.
WARNING
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 is exceeding 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 and shipment.
