Product Description

3 stage PWM solar charger controller

.PWM Control Charger

. Adjustable Loading Timer

.Adjustable Light On + Delay Off Timer

.12V and 24V Battery Auto sensing

Preface

Solar Charge Controller is battery charger that can charge batteries by the power from the solar panels. The charge controller is intelligent for charging batteries, using MCU and professional software to control the step of charging, can prolong the batteries' life.

It has full self protection, protection of overload, short circuit, reverse connection, over charging and over discharging etc.

This model controller is 12V/24 Battery Auto-Sensing.

When the Battery is connected to the Charge controller, the controller will detect the voltage of the battery first, then it will decide how to charge the battery connected.

There are 3 LED indicators and 1 figure LED indicator, 1 button, and 6 terminals covered with the cover.

The first LED indicates the sunshine, when the solar panel connected with the charger is lighted by the Sun, this indicator will be on, otherwise it will be off. The second LED indicates the volume of the battery, when the battery is full, the indicator is green, when the battery is lower, the indicator is red, when the battery is empty, then the indicator will be flashing slowly with red color and auto cut off the load. The third LED indicates load, when it is on, the DC output for the load is on, and if it is off, there is no DC output.

The figure LED indicates the work model of the charger, the setting time or delay time of the charger.

Application

Connecting the solar panel to the solar panel terminals of the charger, "+" to "+" and "-" to "-".

Connecting the battery to the battery terminals of the charger, “+" to “+" and “-“ to “-“.

Connecting the DC load to the load terminals of the charge, take care of the “+" and “-“ of the DC output.

If the panel is charging the battery, the solar panel LED indicator will be on, and the battery volume LED indicator will display the volume of the battery with different color, from red to green.

Press the power button, will control the DC output ON or Off.

Pressing the power button for about 3 seconds, the figure LED will display “0", then you release this button, it indicates that the charger enters the timer setup state, at this state, every press of the power button will make the digital change from “0” to “F”, every figure indicates the timer of the load, for example, if you change the digital as “3”, then the charge will switch on the DC output and will auto switch off the DC output in 3 hours. About all figures, see the table 1.

Table 1, DC Output Time Setting

Digital	0	1	2	3	4	5	6	7
Timer(hour)	no	1	2	3	4	5	6	7
Digital	8	9	A	b	C	d	E	F
Timer(hour)	8	9	10	11	12	13	14	15

Pressing the power button for about 6 second, the figure LED will display “0.”, then you release this button, it indicates that the charger enters the delay time setup state, at this state, every press of the power button will make the digital change from “0.” to “F.” to”-.“, every figure indicates the delay time of the load, for example, if you change the digital as “3.”, then the charge will switch on the DC output when the night is coming and it will auto switch off the DC output in 3 hours. When the charger is at the light controlling state, the “.” will be display at the figure LED. If you don't want the light control function, just reset the delay timer to digital “-.”, when the figure is “0.”, the DC output is light controlled, but no delay time. About all figures, see the table 2.
