Gaia-Wind turbines are developed and manufactured in Denmark. They incorporate more than 20 years of Danish wind industry design experience, which is the design basis for most commercial wind turbines in the market. Because of our modular manufacturing approach we are able to use components that are carefully selected to ensure the highest quality, maximum reliability and low maintenance requirements.
Key Product Features
The Gaia-Wind 11kW turbine has a wide array of features that are usually only found in larger, utility-scale machines.
They include:
Direct grid connection – the turbine is designed to connect directly to the property’s main power source, providing electricity during windy periods and drawing grid power when the wind is still. Grid connection is established with an asynchronous induction generator which eliminates the need for additional inverters.
Triple safety system – the turbine is protected against wind over speeds by a series of redundant safety measures: passive stall control; mechanical brake activation; and deployment of centrifugally activated tip brakes. These mechanisms will ensure that the rotor is ?parked? in wind speeds exceeding 25m/s (56mph).
Advanced turbine controller – manufactured by a leading manufacturer of turbine control systems, our microprocessor controller provides fully automated daily operation of the turbine. Equipped with a wide array of sensors and I/O modules, it continuously monitors and controls performance, safety and power quality conditions. Remote access and operation can be obtained through an optional software package.

Certification
Gaia-Wind is the only small wind turbine manufacturer to have achieved the Danish HB Standards. These certify compliance with rigorous quality, safety and performance requirements.
Gaia-Wind is also participating in an independent testing program conducted by the National
Renewable Energy Laboratory (NREL) in Colorado, where one of our turbines is undergoing five IEC-compliant tests. These activities will result in independently audited performance, noise, and duration data which we will add to our existing technical databases. Ongoing test results can be found on the NREL microsite.
