2 Safety
2.1 Appropriate Usage
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 public 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 plants, diesel
generators, etc.). The manufacturer of the small wind turbine system or the generator must have his
plant approved for operation with this Windy Boy (see also the Windy Boy planning guidelines in the
download area at www.SMA.de/en).
When designing the system, ensure that the permitted operating range of all components is
maintained at all times. Also use appropriate protective measures to ensure that 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).
