Battery Application All types of batteries (charging voltage between 24-85V) Suitable for photovoltaic panel parameters Open circuit voltage 18V-55V Maximum supply voltage 17V-55V Charging module PV power consumption 200W/300W/400W Input PV starting voltage 18V-55V Input PV tracking voltage 17V-55V Output to battery voltage 24-85V (adjustable) Output, to battery current Maximum 15A load loss 0.35W Voltage regulation 1% Load regulation 1% Protection module Battery undervoltage protection Question Battery terminal short circuit protection Question Battery no reverse protection No Over current protection Question Over temperature protection Question Protection class IP66 Operating 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 output of the MPPT controller, the MPPT controller automatically turns off the output and automatically returns to normal after the short circuit is removed.3. Input undervoltage protection When the input voltage of the MPPT controller is lower than 15V, the MPPT will protectively turn off and automatically resume operation after the input voltage is normal.4. Output activate function settingWhen the MPPT controller leaves the factory, the output voltage activation function is enabled. This means that when the output terminal is suspended, the output voltage is closed and the output voltage shows "0" flashing. When access to the battery is detected, the output is automatically activated and the current charging voltage is displayed. When the output activation function is not required in some specific applications, the user can press the [OK] button five times to disable 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 outputs voltage immediately after power-on. If you want to restart the output activation function, press [OK] five times to enable the output activation function. At this time, the output voltage column will display "act" for 3 seconds, indicating that the operation is successful. Once the output activation function is set, the system will save it automatically and operate according to the mode last set when the power is turned on again. Package List: 1 x Solar Battery Charge Controller 1 x User Manual Note: Check before installation: 1. Check whether the appearance is in good condition before installation2. Check the label on the MPPT controller housing to see if the MPTT controller performance specifications match your device.3. The MPPT controller should be fixed on the iron or metal bracket to avoid the machine vibration due to instability.4. The MPPT controller should leave some space around the case for installation.5. Output and input cables should be as short as possible to avoid excessive power consumption during transmission.6. There is high voltage and high current in the machine, and non-professionals cannot disassemble it.7. The 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. How to use: Output voltage setting: Users can directly adjust the output charging voltage of M
