Bergey Windpower Co. 
Introduction Bergey Windpower is the world’s leading supplier of small wind turbines. With installations in all 50 U.S. States and more than 90 countries, and an international network of ~800 dealers, we have the products and experience to put the wind to work for you.At Bergey Windpower, we take pride in offering advanced-technology products that let homeowners and businesses generate their own clean power and even spin their utility meter backwards. Our turbines are also used for off-grid homes, for rural electrification, and to boost the performance of solar electric systems. Products  Wind Turbines By Application: Grid-Connection Grid-Intertie System Bergey wind turbines operate at variable speed to optimize performance and reduce structural loads. Power is generated in a direct drive, low speed, permanent magnet alternator. The output is a 3-phase power that varies in both voltage and frequency with wind speed. This variable power (wild AC) is not compatible with the utility grid. To make it compatible, the wind power is converted into grid-quality 240 VAC, single phase, 60 hertz power in an IGBT-type synchronous inverter, the GridTek Power Processor. The output from the GridTek can be directly connected to the home or business circuit breaker panel. Operation of the system is fully automatic. Back to top Battery Charging Hybrid Power Systems Bergey wind turbines used in combination with a back-up diesel generator, and with optional photovoltaics (PV), provide a cost-effective and reliable alternative to conventional methods of electricity supply in remote areas. For home and village power applications Bergey technology includes advanced system architectures featuring state-of-the-art sine-wave, bi-modal DC-AC power inverters. For telecommunications and smaller village power applications, Bergey hybrid systems often incorporate photovoltaic subsystems to take advantage of the complimentary seasonal variations in wind and solar power. Bergey hybrid power systems are available from 1 kW to over 150 kW. Back to top Water Pumping Wind-Electric Pumping Systems The power requirements for standard centrifugal pumps are well matched to the output of BWC windturbines. This allows a properly sized pump and motor to operate very efficiently over a wide range ofwind speeds. Volumetric pumps, such as jack pumps, are more of a challenge, but can also operated effectively. There are several advantages to the wind-electric pumping systems: 1) The wind turbine can be placed at some distance from the well (borehole) or other water source, 2) Unlike mechanical windmills, these systems require no scheduled maintenance, and 3) These systems are capable of pumping the higher water volumes necessary for community water supply and small-plot irrigation. Wind-electricpumping systems are much less costly to install than solar pumping systems and they are much less costly to operate than diesel pump systems. Back to top |
