2.1 Appropriate Usage

The Windy Boy Protection Box converts the variable AC voltage of a small wind turbine system into
DC voltage. The Windy Boy Protection Box sends the DC voltage to the wind power inverter. At the
same time, the Windy Boy Protection Box protects the wind power inverter against overvoltage.
Depending on the device type, the Windy Boy Protection Box restricts the DC voltage to 400 V,
500V or 600 V (see section10”Technical Data”,page22).

The Windy Boy Protection Box has been designed to allow up to 3 wind power inverters to be
connected. Various combinations with SMA wind power inverters are possible (see the
TechnicalInformation "Windy Boy Protection Box" at www.SMA.de/en).

The output voltage and output current of the small wind turbine system, among other factors,
determine the systems for which the Windy Boy Protection Box is suitable. Observe all restrictions
imposed by the manufacturer. Ensure that the permitted operating range of all components is
maintained at all times.

The Windy Boy Protection Box is only suitable for use with original SMA accessories or with
accessories recommended by SMA Solar Technology AG.

Do not use the Win dy B oy P rot ect ion Box for p urp ose s ot her tha n those described here. Modifications
and the installation of components void the warranty claims and operation permit.

This guide forms part of the Windy Boy Protection Box. Follow all tasks in this guide. Keep this guide
in a convenient place for future reference.
