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 90℃, the MPPT controller will automatically resume operation. 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. INPUT UNDERVOLTAGE PROTECTION: When the input DC voltage of the MPPT controller is lower than 15V, the MPPT will protectively shut down and automatically resumes operation after the input voltage is normal. PREINSTALLATION INSPECTION: 1. Check the appearance is normal before installation. 2. Check the label on the MPPT controller enclosure to verify that the specifications and performance of the MPTT controller match the equipment.
