1、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 rotation speed, and also can improve the utilization rate of wind turbine power generation by 15%‑20% under the same conditions. 2、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 waterproof protection with a rating of IP67 or more. Also includes lightning protection, automatic overvoltage braking, reverse battery connection and open circuit protection. 3、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 current charging, resulting in a safe and stable working condition and increased service life. 4、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. 5、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 and the battery. 6、LED Indicator: The wind turbine charge controller has an LED indicator to clearly see its operating status and avoid accidents. 1 x Wind Turbine Charge Controller Item Type: Wind Turbine Charge ControllerMaterial: Aluminium alloyCharging Mode: Equal ChargeVoltage: 48VProtection Level: IP67Protection Function: Battery and temperature protectionStatic Current: 15maFan Input Power: 300W-800WApplicable Battery: ColloidProtection Mode: Overcharge protection, reverse connection protection, short circuit protection, high temperature protection, overload, lightning protection, fan current limit, automatic brakeDisplay Mode: LED indicationFan Boost Starting Voltage: 24V voltage (48V battery)Battery Overcharge Protection Voltage: 58.6V (48V battery)Exit Overcharge Protection: 57.4V (48V battery)Working Ambient Temperature: -35℃-70℃ LED indicator status Indication content Status Function Green Fan charging indication Always off Fan not connected or no air condition Always on Fan charging status Red Wind turbine brake indication Always off Controller in normal operation Always on Battery over voltage or over temperature protection
