Efficient MPPT controller algorithm, overall rate>98%;RS485 communication is convenient for customers to integrate management and secondary development. Charging method: three-stage charging: constant current, constant voltage, floating charge, extending battery life; Customers can choose the battery type (lead-acid battery, gel battery, lithium iron phosphate, ternary lithium) and charging current, and can also customize the charging parameters to charge other types of batteries; With current limiting charging function, when the user's battery board power is too large, the controller automatically maintains the charging power, and the charging current will not exceed the rated value; High-definition LCD display, you can view equipment operating data and working status in real time;
