Mechanical characteristics of the G-11 HAWT
With its refined rotor and maintenance-friendly setup, the G-11 delivers smooth, reliable energy output for hybrid and distributed power systems.
Blades
Single piece glass fibre blade maximises strength and minimises connection interfaces, limiting points of potential failure.
Swept Area
Superior performance in moderate wind speeds due to the large swept area of 133 m² maximises power output.
Generator
Induction generator produces 3 phase, sinusoidal output without the need for power electronics, simplifying the control system and increasing the reliability of the system.
Anemometer
Wind speed sensor accurately tracks the behaviour of the wind in real time, in order to improve the turbine’s performance and safety.
Work Basket
Built-in work basket and ladder allow servicing and maintenance to be performed easily and safely, at a reduced cost, without the need for specialist lifting equipment.
Gearbox
Fixed ratio gearbox with a constant rotor speed ensures a low-level noise profile is maintained even during high wind speeds.
Controller & Monitoring
Remote monitoring allows service engineers to assess the status and health of the wind turbine, ensuring the system is operating at peak performance at all times.
