ECO 1200 1.2 kW Vertical Axis Wind Turbine The Windterra ECO1200 Wind Turbine is a revolutionary Vertical Axis Wind Turbine (VAWT). Thanks to its advanced technical design, the ECO1200 is ideally suited to both rural and urban installations, generating green energy from a freely available source -- the wind! Wind generation provides a viable solution for addressing such issues as the increasing demand and cost of power, and directly addresses world environmental issues. The advantages of the Windterra ECO1200 Vertical Axis Wind Turbine system are in its revolutionary design: · Omni-directional: The ECO1200 can instantaneously accept wind from any direction as opposed to HAWTs (Horizontal Axis Wind Turbines, which require an on-board motor to rotate the unit relative to wind direction. · Turbulent-wind friendly: The ECO1200 is easily roof mountable and is less affected by turbulent air, making ECO1200 suited for areas where houses and trees may disturb airflow. · Low rotation speed: The ECO1200 rotates up to 190rpm during normal operation and has a maximum rpm of 330 rpm. · Industry-leading annual output: The ECO1200 blade design is optimized for performance at typical lower wind speeds. The result is a higher annual output which makes the ECO1200 a cost effective choice for green energy. · All-in-one system: The ECO 1200is a complete power-generation package, including turbine, controller/inverter, and mounting system. This system can typically be installed and ready to use in six to eight hours. · Roof-top mounting: The ECO1200 is designed for roof top use, eliminating the need for a pole or tower installation that significantly increase cost and complicate routine maintenance.
