Key technical characteristics of the E-20 HAWT
Every detail of the E-20 is built to support sustained power delivery in commercial, remote, and industrial settings, with enhanced stability and control.
Wind Turbine Blades
Profiles optimized using CFD simulations and made with the latest resin compounds based on acrylic urethane and epoxy in compibantion with composite carbon and glass fibre.
Variable Pitch Blades
Patented, active variable pitch system with passive safety features offers accurate control of the position of the blades and protects automatically in case of system failure.
Generator
Permanent magnet generator of 40 poles, 20 kW maximum power at 120 rpm and 1,700 Nm provides a high level of energy performance.
Hydraulic Blade Control
Hydraulic system based on a highly precise position sensor determines the position of the blades according to the control algorithms.
Anemometer
Wind speed sensor accurately tracks the behaviour of the wind in real time, in order to improve the turbine’s performance and safety.
Controller & Monitoring
Configurable controller electronics allows the turbine to adapt to the type of grid or batteries connected, providing maximum energy generation. Remote Monitoring ensures the wind turbine is operating at its peak performance at all times.
