SJ3A PWM Solar Charge Controller 12V3A Light Control Time Control

Functions:
- Equipped with the MCU,artificially controlled.
- Equipped with device to avoid the over charge,over release,electronic short circuit,over loading,battery inversely connecting,solar battery inversely connecting.
- The series connection PWM circuit is implemented to form the major charging circuit,make the voltage loss 50%  lower than the diode charging circuit,and the charging efficiency 3%-6% higher than the non-PWM.
- The LED displyer shows the batteries current situation to make the customer get the information of the batteries.
- The controller can automatically identify the voltage of 12V.
