Backflow prevention: the battery will not burn when it is poured back. When the sun is insufficient and there is no charging current, there will be 0.5-40mA backflow current. It is recommended to connect the diode when charging.
Charging steps of solar cell:
1. Measure the no-load voltage of the solar panel (with sufficient sunlight), calculate the MPPT voltage=0.75 * no-load voltage, or directly check the Vmp parameter value of the manufacturer's panel.
Note that the positive and negative electrodes shall not be connected reversely.
2. The solar panel is connected to the module to supply power, switch to the MPPT voltage display interface, adjust the MPPT potentiometer, and adjust the value to Vmp voltage.
3. Rotate the CV potentiometer to adjust the output voltage (the size is the floating charge voltage of the charged pool).
4. Short circuit both ends of the positive and negative output poles, rotate the CC potentiometer, and adjust the limiting current (the size is the allowable charging current of the charged cell).
If the power of the solar panel is too small, the MPPT light will be on when the circuit is short circuited. In order to maintain the input constant voltage, the output current will be limited. The current can only be adjusted downward. The current value seen when the MPPT light is off is meaningful.
It is recommended to adjust the current when sunlight is sufficient or constant voltage source is used as input.
5. Connect the battery for charging (note that the positive and negative electrodes should not be reversed). The MPPT potentiometer can be properly adjusted so that the module is always at the maximum power point output.
It is recommended to connect the diode to completely prevent reverse flow.
Note:
1. The input positive and negative poles cannot be reversed, or they will be burned.
2. When the output terminal is connected to the battery, the positive and negative electrodes shall not be connected reversely, or they will be burned.
3. The MPPT voltage is generally set to 0.75 times the open circuit voltage of the solar panel. You can also refer to the nameplate or consult the solar panel manufacturer's Vmp voltage value, which is the MPPT voltage we want to set. The display screen can display the set voltage, which is easy to adjust.
4. The output current limiting (CC) value is generally the allowable charging current of the rechargeable battery. The current setting method is: short circuit the output terminal directly with a wire, look at the current display value and adjust the CC potentiometer. The displayed value is the current limiting value (maximum output current value).
5. The maximum output current of 20A is only limited to when the difference between input voltage and output voltage is small, and the output power does not exceed 300W. The greater the difference between input and output voltage, the lower the conversion efficiency and the more serious the heating. If the heating is too serious, please reduce the power for use, or add a 5V fan (with reserved interface and fan current less than 300mA) to assist in heat dissipation.
