Here are two pictures that a customer sent us of his Windtura 750 Grid Tied using a SunG GTI. The customer asked not to be identified by name or location. The first picture is of his Windtura 750 mounted in the air. I am approximating the tower height to be about 40 feet. The second picture is of the amps being fed into the grid from the SunG/Windtura 750. The outlet looks like a 220VAC residential outlet which means the Windtura 750 is feeding about 625 Watts (220V x 2.84A = 625W) into the grid in this picture! I have no idea what the wind speed was when the picture was taken.
