Freen-H15 Features:
Smart Design, Superior Performance
-
Tail-Fin Assisted Wind Tracking
Freen-H15 uses a free-yaw system with a precision-designed nacelle and tail fin. The turbine continuously aligns itself with changing wind direction, maximizing energy capture without the need for a powered yaw motor—making this 15 kW wind turbine a great choice for decentralized or rural energy systems.
-
Integrated Gearbox and Generator
The turbine’s asynchronous generator is directly coupled with a planetary gearbox for efficient energy transfer and steady RPM. This integrated design minimizes mechanical stress and optimizes performance under a wide range of wind conditions, ensuring long-term durability in a 15 kilowatt wind turbine setup.
-
Aerodynamic Rotor with Blade Tip Brakes
The 5.1-meter fiberglass blades feature a unique tip-brake system that activates automatically at high speeds. When centrifugal force exceeds a threshold, the blade tips pivot to reduce rotor speed—ensuring passive overspeed protection without external intervention. This is a key safety advantage for a 15 kilowatt wind turbine operating in changing wind conditions.
-
Fail-Safe Rotor Brake System
An electromechanical, spring-applied rotor brake is integrated with the generator. By default, it remains engaged and is only released by the control system—keeping the 15 kW wind turbine secure during grid failures or emergency stops. This setup ensures a high level of operational safety, particularly for installations near residential zones or critical infrastructure.
-
Intelligent Stall-Control Blade Geometry
The blade profile is engineered to induce aerodynamic stalling at high wind speeds, preventing excessive rotation. This passive design ensures consistent and safe operation even in gusty wind conditions—an ideal feature for a 15 kW residential wind turbine deployed in variable climates.
-
Built for Easy Maintenance
Designed with accessibility in mind, the Freen-H15 requires only basic annual servicing—simple bearing lubrication and visual inspections. Gearbox oil changes are needed just once every two years, minimizing downtime and lowering operational costs. These features make it especially appealing for those seeking a 15 kW wind turbine with low lifetime service needs.
15 kW Wind Turbine Designed for Performance
The Freen-H15 is a small wind turbine with a rated power of 15 kW, featuring a horizontal-axis design with a three-blade rotor and constant-speed operation. Designed for households, farms, and small businesses seeking a reliable renewable energy solution, it efficiently harnesses wind power.
