Overheating Protection: <br>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 degrees Celsius , the MPPT controller will automatically turn off the output. When the internal temperature of the MPPT controller is lower than 85 degrees Celsius , the MPPT controller will automatically resume operation.<br>2. Short Circuit Protection: <br>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. <br>3. Input Under Voltage Protection: <br>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. <br><br><b>Package List:</b><br><p>1 x Solar Charge Controller</p><p>1 x English User Manual</p> <br><br><b>Note:</b><br><div>Check Before Installation:</div><div>1. Check whether the appearance is in  condition before installation; </div><div>2. Check the label on the MPPT controller housing to verify that the performance of the specification MPTT controller matches the device; </div><div>3. The MPPT controller should be fixed on an iron or metal bracket to avoid the vibration of the machine due to instability; </div><div>4. The MPPT controller should leave a certain space around the casing for installation; </div><div>5. The output and input wires should be as short as possible to avoid excessive energy consumption during transmission; </div><div>6. There is high voltage and high current in the machine, and non professionals are not allowed to disassemble it; </div><div>7. Input and output terminals should be reliable and not loose to avoid heating at the connection point. </div><div><br></div><div>The product is not a  model, the controller is produced directly from raw materials
