Product Description Hnew 20A PWM China solar charge controller for solar system (CMTP01-DU20A)CPT series solar charge controller is a specially for the sunshine of the good development of a region and a separate simplified controller Suitable for 12V automatic control system, and some models with USB5V / DC12V output, to facilitate the use of smart devices and lighting.Features:Electronic protectionFully automatic operationPWM charge mode (SOC)Micro-controller digital accuracySuitable for all 12/24V DC lampsBig terminals, big distance between terminalsDouble digital LED display, numbers equal to timer settingTemperature compensation (with external temperature sensor)Indicator LED1.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 ControlHigh efficient Series PWM charging with temperature compensationCompact sizeUse MOSFET as electronic switch,without any mechanical switchDigital LED menu, only one key choose the battery typeLoad status displayGel,Sealed and Flooded battery type optionBig terminals and big distance between terminalsElectronic protection:Overheating,over charging,over discharging,overload,and short circuitReverse polarity protection:Any combination of solar module and batteryIn-build high accuracy constant current (LED Driver),with 91%-96% output efficiencyHigh efficiency series PWM chargingOver-load,Load short-circuit,PV/battery reverse polarity protection,ect.A setting button to set adjustable lighting control optionFull power timer,Second timer,Third timer,hours to dawn timer are option with different output powerWith 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 LightsNotice1.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 controlSolar street light systemSolar garden light systemSolar billboardSolar 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 function1.Over-load protection2.Short circuit protection3.Reverse discharging protection4.Reverse polarity protection5.Protection from the lighting strike6.Under-voltage protection7.Over-charging protectionContact Us:1.All of our products was passed strict Test and Inspection before we shipped.If you are satisfied with our products, please leave us a feedback in 5
