2.1 Intended Use
The Windy Boy is a wind energy 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 a Windy Boy
Furthermore, the Windy Boy can be used as an inverter for power conversion units based on
permanent magnet generators (hydro power system, combined heat and power plant, diesel
generator, etc.). The manufacturer of the small wind turbine system or generator should have
approved his plant for operation with this Windy Boy (also see the Windy Boy planning guidelines in
the download area at www.SMA.de/en).
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).

Derating
A controlled reduction in performance, usually dependent on component temperatures.
SMA Power Balancer
The SMA Power Balancer is a serial feature of the inverter. The SMA Power Balancer prevents the
formation of an unbalanced load > 4.6 kVA (in Italy > 6 kVA) during three-phase feed-in. To this effect,
3 Windy Boys are connected via a control line to a 3-phase feed-in unit.
Varistor
The varistors protect the electronics in the inverter from atmospherically coupled energy peaks, such
as may occur when lightning strikes nearby.
