2.1 Intended Use
The Windy Boy is a wind power inverter, which converts rectified current of a small wind turbine
system into AC current and feeds this energy into the power distribution grid, domestic grid or the
Sunny Island system.
Principle of a small wind turbine system with Windy Boy
Furthermore, the Windy Boy can be used as an inverter for power conversion units based on
permanent magnet generators (hydro power systems, combined heat and power plant, diesel
generator, etc.). The manufacturer of the small wind turbine system or generator must have approved
his plant for operation with this Windy Boy.
When designing the PV plant, ensure that the permitted operating range of all components is
maintained at all times. In addition, ensure that through the use of appropriate protective measures
the maximum permissible input voltage of the inverter is not exceeded. SMA Solar Technology AG
offers you the corresponding components, such as the Windy Boy Protection Box
(overvoltage protection for wind power inverters including the rectifier).
