3 Turbine operation
The Windy Boy is a single phase inverter that converts DC current into AC current and feeds the
energy generated by a wind turbine system into an existing power supply system.
The Windy Boy inverter has a special operating mode for wind generators (see figure below). That
allows performance adjustment to the characteristic curves for generators of many different
manufacturers. In this way maximum yields can be obtained from your wind turbine system.
Figure 2: Display operation mode
The mechanical power of the wind turbine is delivered to the Windy Boy in the form of a direct,
rotational-speed variable DC voltage (RPM) and current intensity (torque).
Most small wind turbine systems have a permanent magnet generator. For converting the variable
frequency AC generator voltage into DC current a rectifier like the Windy Boy Protection Box is
needed.
If a different operation mode is displayed:
• Activate the operating mode "Turbine" by using Sunny Data Control.
• If problems occur contact the SMA Serviceline.
