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.
