3A 12V/24V PWM Solar Power Charge Regulator for Solar System with LED Display, Workable for Home System or Solar Light (Adjusted according to actual requirement)

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,battery inversely connecting,solar battery 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 6V/12V,12V/24V.

Indication instruction of LED light

LED	State	Function
Charge	off	Night condition or the battery not connected
	Green light on	Battery at balanced charging situation
	Slow flash	Battery at floating
	Double flash	Day condition
Battery	Red light double flash	Voltage of Battery under 11.0V
	Green light double flash	Battery low voltage alarm(11V~12.0V)
	Green light Slow flash	Voltage of the battery is normal(11.5V-12.5V)
	Green light on	Voltage of the battery is higher than 13.0V
Protection	Red light slow flash	Battery low voltage cut or high voltage cut
	Red light double flash	The protection of the load short
	Red light on	The protection of the over load
	All light in sequence	The controller automatic system voltage

Install and use

1,The preparation of the conducting wire:calculate the length of the wire ,and then figure out the installation place,make sure the length of the wire is reasonable to decrease the loss of the electricity.

2,Connect the battery first,pay attention to the anode and the cathode to avoid the inverse connection.the indicator light of the battery will work if the connection is correct,otherwise,it will not ,but the component of the controller will not be damaged.

3,Connect the wire of the solar panel, pay attention to the anode and

the cathode to avoid the inverse connection.if the connection is correct,the indicator light of “CHARGE”will be on or flash 10 seconds later after laying outside under the sun,otherwise,please check the connection.make sure the solar energy panel is laid outdoors under the sunshine.

4,Connect the load at the end,pay attention to the anode and the cathode to avoid the inverse connection .if inverse connection ,the led lamp may be damaged.

 

Suitable usage range

The controller is only suitable for the solar energy system with the rated voltage of 6V/12V/24V, batteries can be flood or seal,also can be lithium Iron Phosphate Battery.Please offer the category of the battery before ordering.

 

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 battery and the controller.

4,Please comply with the manufacturer`s safety advice.
