Details:
 
The solar charge controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery.

This controller is a kind of intelligent, multifunctional solar charge controller. There series products adopt customized LCD display screen, which makes the operation on the interface rather convenient. All the controlling parameters can be reset flexibly to satisfy your different needs. It has the following features:
  • Image of LCD graphic symbol 

  • Simple button operation 

  • Automatic Identification System Voltage level 

  • Intelligent PWM charge mode

  • Automatic Temperature Compensation 

  • Adjustable charge-discharge control parameters 

  • Settable Operating mode of Load 

  • Overload, Short Circuit Protection 

  • Remote monitoring and control function (custom) 

  • Battery reverse-discharge protection 

  • Battery Low Voltage Disconnection (LVD) 

  • Battery reverse connection protection 

  • Accumulated function of charge and discharge Ampere hours
