    ▲ Preface

    ●Gaia New Energy Technology Co., Ltd does not authorize any products to be used in life support devices or systems.

    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.

    ▲ Layout

    The controller has 1 LCD displayer, 1 button, and 6 terminals covered with the cover, see the picture 1.

    The LCD has two-row, it will display the voltage of battery, the charging state, the DC output ON/OFF state, timer information and light control & delay time information, see picture 2 and picture 3.

  • Picture 2
  • Picture 3
  • There are 4 areas on the panel of LCD. Left-up displays the voltage of battery. Left-down is a bar, when the sun is shining, and the solar panel is charging the battery, the bar will rotate from left to right, and the length will be from short to long; when there is no sunshine, the bar will not rotate, just display the state of the battery, if the battery is full, the bar is long, and if the battery is empty, then the bar is short. Right-up displays the regular time or the light control state. Right-down display the DC output state, if the DC output is on, then it will display “Load: Y”, if the DC output is off, then it will display “Load: N”, if the load is too big, an overload is caused, it will display “Load: O”, and if the load is short circuit, the it will display “Load: S”.

    ▲ 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 controller isn’t at the setup state, regular time state, or light control and delay time state, press the power button, will control the DC output ON or Off.

    Pressing the power button for about 2 seconds, the right-up area will show “Time :00”, and the figures will flash, then you release this button immediately, it indicates that the controller enters the timer setup state, at this state, every press of the power button will make the figures change from “00” to “15”, the figures indicate the power on time of the DC output , for example, if you change the digital as “03”, then the charge will switch on the DC output and will auto switch off the DC output in 3 hours, If the figures are “00”, it means that the regular timer is invalid. When you don’t press the button for about 4 seconds, then the controller will quit the setup state automatically. Pressing the power button for about 4 second, the right-up area will show “L+D :00”, and the figures are flashing, then you release this button, it indicates that the charger enters the light control and delay time setup state, at this state, every press of the power button will make the digital change from “00” to “15”, figures indicate the delay time of the load, for example, if you change the digital as “03”, 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 you don’t press the button for about 4 seconds, then the controller will quit the setup state automatically. When you set it as “L+D :00”, then it means the controller is at light control and no delay time state, it will switch on the DC output when the night is coming, and will switch off the DC output when the day time is coming. When the controller is at the light control state or light control and delay time state, you can’t switch on the DC output by the button in day time, but you can switch off the DC output at night. If you don’t want the light control function, just set the controller to “Time :00” state. When the voltage of the battery is too low, the controller will automatically switch off the DC output, in order to protect the battery to be over-discharged.
