2 Safety
2.1 Intended Use
The Windy Boy is a wind power inverter, which converts the rectified current generated by a small
wind turbine system into AC current and feeds this energy into the electricity grid, domestic network
or the Sunny Island system.
Principle of a small wind turbine system with Windy Boy
In addition, the Windy Boy can be used as inverter for energy converters 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 generator must have approved his plant for
operation with this Windy Boy.
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG.
When designing the PV plant, ensure that the permitted operating range of all components is
complied with at all times. Moreover, make sure that appropriate protective measures are in place to
ensure that the maximum permissible input voltage is not exceeded. SMA Solar Technology AG offers
you the necessary components, such as the Windy Boy Protection Box (overvoltage protection for
wind power inverters including the rectifier).
