WIDE RANGE OF USES: Suitable for solar street light controllers, solar chargers, solar electric bicycle, solar electric tricycles, solar toy cars, household solar panels, solar monitoring and other usage scenariosSpecification:Item Type: Solar Battery Charge ControllerProduct Size: Approx. 120 x 80 x 40mm / 4.72 x 3.15 x 1.57inEfficiency: 95%Noise: <55dBUses: Solar street light controllers, solar chargers, solar electric bicycle, solar electric tricycles, solar toy cars, household solar panels, solar monitoring and other usage scenariosWeight: 485 g / 17.1 oz(approx.)Applicable batteryAll kinds of batteries (charging voltage between 24-85V)Suitable for photovoltaic panel parametersOpen circuit voltage18V-55VMaximum power voltage17V-55VCharging modulePV input power200W/300W/400WPV input starting voltage18V-55VPV input tracking voltage17V-55VOutput to battery voltage24-85V (adjustable)Output to battery currentMaximum 15ALoad loss0.35WVoltage regulation1%Load regulation1%Protection moduleBattery undervoltage protectionHaveBattery terminal short circuit protectionHaveBattery non reverse protectionNoneOvercurrent ProtectionHaveTemperature protectionHaveProtection classIP66Operating temperature-40~+651.OVERHEATING PROTECTIONWhen the internal temperature of the MPPT controller exceeds 100, 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 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..Package List:1 x Solar Battery Charge Controller1 x User ManualNote:Check before installation:1. Check whether the appearance is in good condition before installation2. 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 nonprofessionals are not allowed to disassemble it.7. Input and output terminals should be reliable and not loose to avoid heating at the connection point.8. The product is not a smooth, unpolished controller made directly from materials.
