1. Safety Information

  • Read all instructions in the manual before installation.
  • Do not attempt to disassemble or repair the charge controller.
  • Install an external fast-acting fuse or circuit breaker if necessary.
  • Disconnect the solar panel and the fast-acting fuses/circuit breakers at the battery before installing or moving the charge controller.
  • Ensure that power connections are tight to prevent overheating due to loose connections.
  • Only charge batteries that comply with the charge controller's parameters.
  • The battery connection can be a single battery or a battery bank.
  • Risk of electric shock! The solar panel and load can produce high voltages when the charge controller is operating.

    4. Wiring

    Connect the system in the sequence of 1) battery, 2) loads, 3) solar panel according to Figure 2-2, "Wiring schematic diagram," and disconnect the system in the reverse order.

    Note:

    • Do not connect the circuit breaker or fast-acting fuse during charge controller wiring.
    • Ensure that the "+" and "-" poles are connected correctly.
    • Install a fast-acting fuse with a current rating of 1.25 to 2 times the nominal current of the charge controller, at a distance of no more than 150 mm from the battery.

    Warning: The charge controller does not have reverse connection protection for the solar panel; please connect it correctly.

    5. LED Indicators

    1) Charge and Load Status Indicator

    Indicator Color Status Instruction
    Charge Status LED Green ON Charging
    OFF No charging
    Green Fast flashing Battery overvoltage
    Load LED Green ON Load ON
    OFF Load OFF
    Green Slow flashing Overload
    Green Fast flashing Load short circuit

     

    2) Battery Status Indicator

    • Displays battery status depending on voltage.

    LED1 LED2 LED3 LED4 Battery Status
    Slow flashing × × × Undervoltage
    Fast flashing × × × Over-discharge
    During charging
    ○ ○ × × 12.8V＜ Ubat＜13.4V
    ○ ○ ○ × 13.4V＜ Ubat＜14.1V
    ○ ○ ○ ○ 14.1V ＜ Ubat
    During discharging
    ○ ○ ○ × 12.8V＜Ubat＜13.4V
    ○ ○ × × 12.4V＜Ubat＜12.8V
    ○ × × × Ubat＜12.4V

     Note:

    1. The above voltage values are measured in the 12V system at 25℃; please double the values in the 24V system.
    2. "○" indicates the LED indicator is ON; "×" indicates the LED indicator is OFF.

    6. Operation

    1) Load ON/OFF Setting

    Press the button to control the load output when the charge controller is powered on.

    2) Battery Type Setting

    1. Press and hold the button for 5 seconds to enter the setting mode until the battery status LEDs flash.
    2. Select the desired mode by pressing the button.
    3. The mode will be automatically saved after 5 seconds of no operation, and the LED will stop flashing.

    7. Protection

    • Battery overvoltage protection: Stops charging when overvoltage occurs.
    • Battery over-discharge protection: Stops discharging when undervoltage occurs.
    • Overload protection: Disconnects the load in case of overload.
    • Short circuit protection: Disconnects the load in case of short circuit.
    • High voltage surge protection: Protection against small voltage surges.

    8. Troubleshooting

    • No charge indication: Check the connection of the solar panel and the battery.
    • No LED indicator: Check if the battery voltage is higher than 8V.
    • Fast flashing charge LED: Check the battery voltage for overvoltage.
    • Fast flashing LED1: Battery over-discharged.
    • Slow flashing charge LED: Reduce the number of electrical appliances.
    • Fast flashing charge LED: Check the load for short circuit.
