Features Automatic Battery Matching: This wind turbine charge controller automatically matches 48V batteries. Voltage and current limits are controlled during charging to ensure optimal charging. At the same time, it offers maximum protection for the wind turbine Thermally Conductive Silicone Potting: The wind turbine charge controller is treated with thermally conductive silicone potting, sealing it against water, dust and oxidation of the circuit. Boosted MPPT Technology: This wind turbine charge controller uses boosted MPPT technology, making it continuously more efficient to charge than a PWM charger. It can ensure that the wind turbine can charge the battery under low wind speed and low rotatio Fast Heat Dissipation: The wind turbine charge controller has fast heat dissipation, deep air ducts and a heightened design of the heat dissipation wind tunnel, which effectively solves the heat dissipation problem of the controller in the case of high c Multiple Protection: This wind turbine charge controller is available for 300w‑800w wind turbines. It helps to automatically control the wind turbine charging battery. The brake can be activated automatically when the battery is fully charged. Full water Feature: 1. LED Indicator: The wind turbine charge controller has an LED indicator to clearly see its operating status and avoid accidents.
