Features:
Electronic protection
Fully automatic operation
PWM charge mode (SOC)
Micro-controller digital accuracy
Suitable for all 12/24V DC lamps
Big terminals, big distance between terminals
Double digital LED display, numbers equal to timer setting
Temperature compensation (with external temperature sensor)
Indicator LED
1.Charger LED is used to indicate the charging status of battery, LED turn off means charging stopped.
2.Battery Status indicator:RED ON when battery under voltage, please charging, GREEN ON when the battery full.
3.There is output and load can work if the Load LED is lighting.There isn't output and the load can work is the Load LED off.
Advantage:
Intelligent System Optimum Control
High efficient Series PWM charging with temperature compensation
Compact size
Use MOSFET as electronic switch,without any mechanical switch
Digital LED menu, only one key choose the battery type
Load status display
Gel,Sealed and Flooded battery type option
Big terminals and big distance between terminals
Electronic protection:Overheating,over charging,over discharging,overload,and short circuit
Reverse polarity protection:Any combination of solar module and battery
In-build high accuracy constant current (LED Driver),with 91%-96% output efficiency
High efficiency series PWM charging
Over-load,Load short-circuit,PV/battery reverse polarity protection,ect.
A setting button to set adjustable lighting control option
Full power timer,Second timer,Third timer,hours to dawn timer are option with different output power
With self-dimming capability basing on battery voltage to save energy and realize lamps turn on for 365days.Special for LESS THAN 70W Solar LED Street Lights
Notice
1.Please carefully check and confirm the voltage before wiring the components of the solar panel voltage is 18V, battery 12V, 12V rated voltage of the load.
2.The rated current of solar panels and load must be less than the rated current of controller.
Application:
Ideal for off-grid solar lighting system that needs light and timer control
Solar street light system
Solar garden light system
Solar billboard
Solar detection equipment etc.
Connection ( As indicated in diagram ):
Open the top cover of controller and connect the wire with terminals follow the diagram on the top cover of it.
1.Connection the "+", "-" Poles of the battery to the corresponding ports of controller(the third and the fourth one from left ).* The subsequent operation can be processed only if the load indicator (mark:Load ) flickers once and starts lighting after 30 seconds.
2.Connect the "+" "-" poles of the solar panel to the corresponding ports of controller( the first and the second one from left).
3.Connect the "+" "-" poles of the load to the corresponding ports of connector( the first and the sixth one from left ).
Protection function
1.Over-load protection
2.Short circuit protection
3.Reverse discharging protection
4.Reverse polarity protection
5.Protection from the lighting strike
6.Under-voltage protection
7.Over-charging protection
