Product Description
PWM Solar Charge Controller 30-50A for Home System
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. SR series solar controller will supply perfect protection functions for the batteries, and it will make battery work reliably.
Product Feature:
1. PWM charging mode.
2. Five load working mode.
3. Digital LED display.
3. Over charging protection, over discharging protection, over load, short circuit protection, reverse polarity protection and TVS lightning protection.
5. Temperature compensation function.

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 (14.4V/28.8V/57.6V), the controller will shut down charging automatically. When the voltage drops to the recovery voltage (13.5V/27.0V/54.0V), the battery goes into the floating charging mode. When the charging voltage is lower than recovery voltage (13.3V/26.6V/53.2V), 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 16.5V/33V, the output will be shut down automatically to protect loads.
Accessories: A fuse. The 50A controller uses 2 fuses, while 1 fuse uses 40A fuse.
Application:
1. Could be widely used in the solar system
2. Lamps, pastoral, frontier and island etc.
3. Mobile basics, microwave stations and traffic systems.
