Warnings for usage
1.The batteries has stored much energy,please keep the batteries from the short circuit under any circumstances,we strongly recommend connecting the batteries with the fuse.
2.Please avoid the short circuit wire and the terminal,for the wire and the terminal may generate voltage two times higher than the rated voltage of the controller.Please use the insulated tools while operating the controller.
3.Ensure the children keep away from the and the controller.
4.Please comply with the manufacturer`s safety advice.
Suitable usage range
The controller is only suitable for the solar energy system with the rated voltage of 12V, batteries can be flood or seal,also can be lithium Iron Phosphate .Please offer the category of the before ordering.
Characteritics of the function
1.Equipped with the MCU,artificially controlled.
2.Equipped with device to avoid the over charge,over release,electronic short circuit,over loading,inversely connecting,solar inversely connecting.
3.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.
4.The LED displyer shows the batteries current situation to make the customer get the information of the batteries.
5.The controller can automatically identify the voltage of 12V.
