2.1 Intended Use
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 power distribution 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 plant, diesel
generator, etc.). The manufacturer of the small wind turbine system or generator must have approved
his plant for operation with this Windy Boy.
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).

Load Disconnection Unit
You must install a separate miniature circuit-breaker for each inverter in order to ensure that the
inverter can be securely disconnected under load. The maximum permissible fuse protection can be
found in Section 11"Technical Data" (page76).
Detailed information and examples on the design of miniature circuit-breakers are available in the
Technical Information "Miniature circuit-breaker" to be found in the download area of
SMA Solar Technology AG at www.SMA.de/en.
DANGER!
Danger to life due to fire
In the event of parallel connection of more than one inverter to the same miniature
circuit-breaker, the protective function of the miniature circuit-breaker is no longer
guaranteed. It can result in a cable fire or destruction of the inverter.
• Never connect several inverters to the same miniature circuit-breaker.
• Observe the maximum permissible fuse protection of the inverter when selecting the
miniature circuit-breaker.
DANGER!
Danger to life through electric shock
When a generator (inverter) and a load are connected to the same miniature circuitbreaker, the protective function of the miniature circuit-breaker is no longer guaranteed.
The currents from the inverter and the grid can accumulate to form overcurrents that are not
detected by the miniature circuit-breaker.
• Never connect the load between the
inverter and the miniature circuit-breaker
without protection.
• Always protect the load separately.
NOTICE!
Damage to the inverter due to the use of screw-type fuses as load disconnection
units
A screw-type fuse, e.g., DIAZED fuse or NEOZED fuse, is not a switch-disconnector and
must never be used as such. A screw-type fuse only acts as cable protection.
Disconnection under load using a screw-type fuse can damage the inverter.
• Use o nly a switch-di sconnecto r or a mi niature circui t-breaker as a l oad dis conne ction
