12V/24V PWM Solar Controller 20A Solar System Voltage Regulator
The solar charge controller is one of key components of the PV off-grid solar system;CARSPA ENS series PWM solar controller can adopt different charge way based on different batteries and the environment.It is designed with big clear LCD display with 4 buttons to switch different screens.Double solar panel inputs applied makes it more reliable,and the bottom aluminum radiation can make it work properly when the unit gets hot.
Products Features:
1.Pulse Width Modulation Technology,which offers the good efficiency of your PV system.
2.Automatically detects 12/24V or 24/48V system voltage.
3.LED indicators or LCD display by symbol and data.
4.Temperature-compensated,3-stage I-U curve charge regulation.
5.Full electronic protection -reverse polarity,over-current,short-circuit,over temperature,current drawback,lightning etc.
6.High efficiency.
7.Dual terminals for solar input.
8.Battery type can be:GEL,AGM and solar battery etc.
LCD Screen Display Function:
The PWM controller is equipped with a big LCD display panel and 4 buttons.There is one main window and sever different screens display different states by pressing the menu button to change the states.
If LCD screen in main menu,press"MENU",then change to submenu.If in sunmenu,press "UP" or "DOWN",you can change to different states.
