A small, easily transportable wind turbine system has a square rail base secured to the ground by stakes and by its own weight. Slanted vertical legs connect a smaller square upper support perimeter to the base. A three-section telescoping mast is attached to the base and to the upper support. Winches and guy wires raise the second mast. As the second mast is raised, static guy wires raise the third mast. A wind generating turbine is attached to the top of the third mast. A controller senses the maximum output of the turbine and raises or lowers the height of the masts such that the minimum wind speed necessary to produce the maximum electric output is produced. The controller also feeds energy to a battery storage system and directly to a utility panel.
