V45 Wind Turbine

The V45 wind turbine has a number of features not found in other turbines of this size. They include active pitch and yaw control and a state of the art controller which permits the use of relatively simple mechanical systems to control pitch and yaw. These proprietary devices translate into greater annual power production with increased safety, reliability and lower maintenance, characteristics found only in industrial size turbines.

The onboard computer is capable of numerous diagnostic inquiries and can send real time and cumulative data back to a remote monitoring station for analysis. In addition the computer can be remotely reprogrammed and updated, features which insure your turbine runs optimally with the ability to flag unusual events so they can be analyzed before they become maintenance problems.
