Airdolphin GTO


Airdolphin GTO can connect to an ordinary power grid through a power conditioner. This wind turbine is targeted towards the growing grid-tie market which is centered in developed countries. Not only can it be applied to various uses in daily life or in business, the generated electricity can also be sold to electric power companies in countries with a FIT (Feed-in Tariffs) system. (GTO stands for Grid-Tie Optimized.)
