Bergey 1kW wind turbine, 24 VDC, includes charge controller Classic250
With a rotor diameter of 2.5 meters (8.2 ft) and a peak output of approximately 1300 watts the Excel 1 is intended for the off-grid home market, telecommunication sites, and for rural electrification programs in developing countries. It is also a perfect upgrade system for current owners of solar-only off-grid systems.
Very quiet operation is achieved with advanced rotor design and an oversized alternator that reduces the rotor operating speed.
Low wind speed performance is greatly enhanced by a low-end-boost circuit that optimally loads the wind turbine down to wind speeds as low as 9 km/h (2.5 m/s). Combined with the new blade system, this circuitry allows the Excel 1 to produce useful power more than 6000 hours a year at a typical site. For reference, a typical solar system produces power 3500 hours a year at a typical site.
