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 PROTECTIONWhen 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 UNDERVOLTAGE PROTECTIONWhen the input 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.4.OUTPUT ACTIVATE FUNCTION SETTINGWhen the MPPT controller leaves the factory, the output voltage activate function is on. That is, when the output terminal is suspended, the voltage output closed, and the output voltage shows "0" flashing. When battery access detected, the output automatically activated and the current charging voltage displayed. When the output activation function is not required in some specific applications, the user can press the [OK] key five times to turn off the activation function. At this time, the output voltage column will display "OPE" for 3 seconds, indicating that the operation is successful. In this way, the MPPT controller will output voltage directly after power on. If you need to restart the output activation function, press the [OK] key five times again to turn on the output activation function. At this time, the output voltage column will display "act" for 3 seconds, indicating that the operation is successful. After the output activation function is set, the system will save it automatically, and it will work according to the mode set last time when power on again. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Solar Battery Charge Controller1 x User M
