4)Time Control
Control the load on/off time by setting the 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.

This
product is a step-up
current control,
if the
input voltage is lower
than the rated voltage,
it is not working.
①
Replace the LED light
②
Reduce system rated voltage grade
and replace the product model
For example, 24V system change to
12V system, and replace the
corresponding controller.
①
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.
WARNING: The LVRV can be set, but must be more careful that it maybe
damages the battery if the LVRV is set too low.
9. Technical Specifications
◆
The controller is not recognized system voltage and no temperature
compensation when the battery connects 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 the controller.
The controller is working temperature exceeds 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.
The controller is damaged during transportation and shipment.
Any changes without prior notice!
