Product Features

Efficient MPPT controller algorithm, MPPT efficiency is not less than 99%, and the conversion efficiency of the whole machine is as high as 98%;
Charging method: 3-stage charging(constant current, constant voltage, float charging), which can effectively extend the lifespan of battery;
Mode of Load: Normally Open/Off, Light Control, Time Control. 48V96V battery voltage auto recognition;
User can choose to charge common batteries(Sealed lead-acid battery, Lead-acid gel battery, Open lead-acid battery, Lithium battery), and can also customize parameters to charge other types of batteries;
With current limiting charging function, when the power of solar panel is too high, the controller automatically maintains the charging power, and the charging current will not exceed the rated value;
With HD LCD display, you can view the operating data and working status of devices, and support the modification of the controller display parameters;
Can be connected to an external display.
