Rated battery voltage:48VWind generator braking voltage: 60VWind generator recover voltage: 54VProtection class: IP67Wiring:1. Connect the "+" and "-" of the battery to the positive and negative terminals of the battery of the controller.2. Connect the three-phase output voltage of the wind turbines to the three-phase voltage input terminal of the controller fan.3. When manual brake is required, short the red thin wire to the positive battery, that is, complete the manual brake function. To cancel this function, just disconnect the thin red wire.Indicator status:When the controller green (BATTERY) indicator is on, it indicates that the battery is connected properly.When the controller's green fan access (WIND) indicator flashes, it indicates that the wind turbines is connected. The speed of the flashing reflects the speed of the fan.When the controller red (BRAKE) indicator is on, the battery is fully charged, the wind turbines is automatically braked, or the brake is automatically activated due to overcurrent protection.Colour:orangeMaterial:Aluminum alloyPackage Contents:1 x Wind Turbine ControllerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
