World Power Wind GeneratorsWorld Power started making wind generators in 1978 and now has more years of experience than any other supplier. These systems have both the industry's highest power-to-weight ratio and the lowest cost per watt. They've also introduced more technological innovations and revolutionized wind generator design. New improvements include combining the most efficient, slow speed, PM alternator with a perfectly matched airfoil propeller that assures both maximum output in low winds and the smoothest running in turbulent wind conditions. A unique "angle governor" solves common problems with folding tail and tilt-up governors and greatly extends power output. Easy-to-change output voltage represents another exclusive feature with World Power—you can change your system voltage later and still use the same wind generator (12-48V range). High quality components make these systems last for decades. Only 3 moving parts—no scheduled maintenance required, just an annual inspection. All World Power generators include the EZ-Wire System Centers described below making them both the most economical and reliable wind system choice. 2-year warranty.Tower KitsBasic tower kit includes tilt base and 2 each extra long threaded couplings with eyelets.
