Output to Battery Current Maximum. 25A Load Loss 0.35W Voltage Regulation 1percent Load Regulation 1percent Protection Module Battery Under Voltage Protection Yes Battery Terminal Short Circuit Protection Yes Battery Anti Reverse Protection No Over Current Protection Yes Temperature Protection Yes Protection Class IP66 Working Temperature -40 celsius ~+65 celsius 1. Overheating Protection: When the internal temperature of the MPPT controller exceeds 100 degrees C, the MPPT controller will reduce the output power. If the internal temperature continues to rise to 110 celsius , the MPPT controller will automatically turn off the output. When the internal temperature of the MPPT controller is lower than 85 celsius , 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.. Package List: 1 x Solar Charge Controller1 x English User Manual Note: Check Before Installation:1. Check whether the appearance is in good condition before installation; 2. Check the label on the MPPT controller housing to verify that the performance of the specification MPTT controller matches the device; 3. The MPPT controller should be fixed on an iron or metal bracket to avoid the vibration of the machine due to instability; 4. The MPPT controller should leave a certain space around the casing for installation; 5. The output and input wires should be as short as possible to avoid excessive energy consumption during transmission; 6. There is high voltage and high current in the machine, and non professionals are not allowed to disassemble it; 7. Input and output terminals should be reliable and not loose to avoid heating at the connection point. The product is not a smooth model, the controller is produced directly from raw materials without polishing.
