2 Safety
2.1 Intended Use
The Windy Boy is a wind energy inverter which converts the rectified current of a small wind turbine
system into AC current and feeds this energy into the electricity 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-electric 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 requisite components, such as the Windy Boy Protection Box (overvoltage protection
for wind power inverters, including the rectifier).

2.2 Safety Precautions
DANGER!
Electric shock caused by high voltage in the inverter
Even when no external voltage is connected, there may still be high voltages present in the
inverter. The following work may only be carried out by trained, electrically qualified
personnel:
• Electrical installation
• Repairs
• Modifications
CAUTION!
Risk of burns through contact with the enclosure during operation
• Only touch the enclosure lid and the display during operation.
CAUTION!
