12v/24v/48v 30A PWM solar charge controller , light and time control

详情

This instruction can be applied to *2V**8V,*0A controller.
Summary:The solar controller is the most important part of the solar system. It can intelligently and automatically control the charge, discharge and load of the system. The performance of the controller is related with the stability of the system, especially the lifetime of the batteries. CQ series solar controller will supply perfect protection functions for the batteries, and it will make battery work reliably. And the controller could be widely used in the solar system such as lamps, pastoral, frontier and island and so on, it is also could be used for mobile basics, microwave stations and traffic systems.
 
Theory introduction:Use the industrial MCU as the host controller. By sensing the ambient temperature, the voltage and current of battery and solar panel, the controller switches the MOSFET on or off to achieve the function of control and protection.
※Battery Reversed protection : If the "+" and "-" polarity reversed, please replace the fuse.
※Solar Panel Reversed protection: If the "+" and "-" polarity reversed, please replace the polarity.
※Overload and short circuit protection: If it happens that the load exceeds rated current or load short circuit, please replace the fuse.
※Battery Open-circuited protection: When battery open-circuited, but the solar cell charging normally, the controller will cut off the load.
※Overcharge protection: When the battery voltage is higher than protection voltage (*4.4V/*8.8V/*7.6V), the controller will shut down charging automatically. When the voltage drops to the recovery voltage (*3.5V/*7.0V/*4.0V), the battery goes into the floating charging mode. When the charging voltage is lower than recovery voltage (*3.3V/*6.6V/*3.2V), the floating charging mode will be ended, and the bulk charging mode will be activated.
※When the battery voltage goes under protection voltage, the controller will shut down the output automatically to protect the battery.
※Over-voltage protection: When the voltage is higher than *6.5V/*3V, the output will be shut down automatically to protect loads.
