Vertical Axis Wind Turbine Generator Color: Green Model size: 12_400W (12 Volt, rated power 400W) Key benefits Reliable low wind starting and steady power production. Starts turning at 1.3 m/s and begins charging at 2.5 m/s, making it suitable for areas with light to moderate winds. Stable and durable rotor. One piece blade design and two blades provide higher rotational stability and consistent output at rated wind speeds. Low start torque and long service life. Coreless permanent magnet generator design reduces start torque and wear. Built in overspeed protection. Maximum rotation is limited to 300 RPM regardless of wind speed and electromagnetic brake plus unloading unit provide overspeed and overload protection. Flexible compatibility. Rated voltage options include 12 V and 24 V. 48 V can be customized for the 600 W version. MPPT charge controller is available for efficient battery charging and automated protection. Main features Rated power options: 100 W, 200 W, 300 W, 400 W, 500 W, 600 W. Max power for the 400 W model is 450 W. Wind performance: start wind speed 1.3 m/s, cut in 2.5 m/s, rated wind speed 11 m/s, safe continuous wind up to 40 m/s, instantaneous maximum wind speed up to 45 m/s. Generator: three phase permanent magnet synchronous motor with coreless PMG design for low start torque and extended life. Blades: two blade configuration. Blade material options include glass fiber, basalt, or nylon carbon fiber depending on application and availability. Nylon carbon fiber blades are lightweight, corrosion resistant, and water resistant. Control system: electromagnetic control system for precise operation and protection. Protection and durability: generator protection grade IP54. Electromagnetic brake provides overspeed protection. Electromagnetic brake and unloading unit provide overload protection. Mechanical and installation: recommended mount height 7 to 12 meters, typical installation height 9 meters. Product assembly weight less than 20 kg. Maximum RPM protection ensures rotor speed does not exceed 300 RPM. Environmental limits: VAWT operating temperature 25 to 45 degrees Celsius, controller 10 to 45 degrees Celsius, inverter 0 to 40 degrees Celsius. VAWT relative humidity up to 90 percent, controller and inverter up to 80 percent. Suitable for altitudes up to 4500 meters. Charge controller and system MPPT charge controller available. Features include low speed start, utilization of wind energy, low vibration, and efficiency. Wind energy charging controller supports intelligent battery charging and automatic battery protection. The controller is configured for 12 V systems by default. 24 V and 48 V configurations are available depending on model and . Tail fin and yaw adjustment system allow the rotor position to be adjusted to capture available wind energy more effectively. Why this turbine solves common problems Produces usable power in low wind conditions where conventional turbines may not start. Built in overspeed and overload protection reduce the need for frequent maintenance after gusts or storms. Lightweight assembly and simple screw and play installation reduce installation time and labor. Multiple voltage and blade material options allow matching to battery systems and site conditions.
