1?��High Efficiency: With high conversion efficiency, clear LCD backlight display, efficient MPPT algorithm. Simple in operation and high in efficiency. 2?��Practical Using: Wide input PV voltage 150V, suitable for various common solar panel, also supports 3 types of commonly used batteries, and you can customize the parameters to charge other types of batteries. 3?��Safe in Working: Using ultra low power consumption power chip to reduce static standby energy consumption and nighttime energy loss. And the LOAD mode includes normally open, normally closed mode, light control mode, dual period control mode, and light control fixed time control mode. 4?��Auto Recognizing: Automatic identification of battery system voltage. Allows for 3 stage charging, constant current, constant voltage, floating charge, which can effectively prolong the life of the battery. 5?��Better Charging: With current limiting charging function, when the battery board power is too large, the controller automatically maintains the charging power, and the charging current will not exceed the rated value. 6?��Communication: RS485 communication can provide communication protocol, which is convenient for you to integrate management and secondary development. Supports PC software monitoring, support WiFi module expansion to realize APP cloud monitoring.
