1. Overheating Protection:

When the internal temperature of the MPPT controller exceeds 100 °C, the MPPT controller will reduce the output power. If the internal temperature continues to rise to 110℃, the MPPT controller will automatically turn off the output. When the internal temperature of the MPPT controller is lower than 85℃, the MPPT controller will automatically resume operation.

2. Short Circuit Protection:

When an unexpected short circuit occurs in the MPPT controller output, the MPPT controller automatically turns off the output and automatically returns to normal after the short circuit removed.

3. Input Under Voltage Protection:

When the input voltage of MPPT controller higher than 17V, it starts working. When the input voltage is lower than 1.1 times of the rated output voltage and the charging current is lower than the cut off current, the system will turn off the charging and turn off the display. When the input voltage of the MPPT controller is lower than 10V, the MPPT will protectively shut down and automatically resumes operation after the input voltage is normal.
