Feature:1. EXQUISITE WORKMANSHIP: Industrial grade components and strict manufacturing processes. Suitable for relatively harsh working environments such as low temperatures. It also has reliable performance and service life.2. EFFICIENT CONVERSION: The charging controller adopts PWM technology with MOS tubes connected in series, making solar and wind energy charging more efficient. Especially the MCT charging function tracks the maximum current of the solar panel in real time.3. ALUMINUM ALLOY MATERIAL: The wind generator controller adopts an aluminum alloy shell and a multilateral bottom plate design to increase the heat dissipation area. Therefore, the controller can maintain optimal heat dissipation for a long time.4. IP67 WATERPROOF: Fully waterproof protection with a rating of IP67. Wind and solar charging controllers can work stably even in very humid environments.5. MULTI PROTECTION: Overcharging voltage, undervoltage and overload voltage protection, battery reverse connection and open circuit protection, etc. Use our controller with confidence!Specification:Item Type: Wind Turbine ControllerMode: FW20 48Material: Aluminum Alloy Rated Voltage of Battery: 48VNameplate Capacity of Wind Turbine (Maximum): 2000WBraking Voltage of Wind Turbine: 60VRecovery Voltage of Wind Turbine: 54VStatic Power Consumption: Less than or equal to 15MAWaterproof Level: IP67Features:Adopting high speed MCU and dedicated control algorithm design, making control more advanced and intelligent.

The unique and innovative debugging method provides users with a simpler and faster way to use. The SR SL series controller has full function protection measures such as short circuit, overload, anti reverse protection, automatic shutdown and recovery when fully charged or over discharged, and detailed charging indication, battery status, load, and various fault indications. 12V, 24V voltage automatic identification.Application Area: Solar street light Solar Garden Light Solar insecticidal lampSmall solar power plant systemVarious wind DC power supply systems.Package List:1 xWind Turbine ControllerNote:1. Confirm that the output voltage of the wind turbine is consistent with the rated voltage of the battery.2. Connect the wires in the following order, first connect the positive and negative poles of the battery, and then connect the three phase voltage output of the fan.3. Please strictly follow the instructions to connect the battery and wind turbine generator to the controller. Reverse polarity or incorrect connection can contribute to abnormal system operation and even complete damage to the controller.
