Inverters Grid Tie for connecting Wind Turbines to mains Electricity
WINDY BOY - grid-coupling small wind energy plants
The grid-coupling of small wind energy plants is simpler than ever - with the Windy Boy from SMA. It converts the variable frequency voltage from wind generators into grid conforming AC voltage. Thus the energy can be used privately, excess energy fed into the mains grid and respectively remunerated. The Windy Boy works perfectly together with the Sunny Island in stand-alone grids for the electrification of remote areas.
The Windy Boys are suitable for wind generators from a wide variety of manufacturers and power classes. They guarantee an optimal power adjustment and very high energy yields.
They are also best suited for flexible and worldwide use - ensured by the robust housing, the SMA Grid Guard disconnection device, the electric separation to the grid along with an automatic 50 or 60 Hz recognition.

Optimal protection for small wind power plants
Rectifier and overvoltage protection – the Windy Boy Protection Box from SMA is multitalented: it protects the inverter from excessive generator voltage, while at the same time, it diverts excess power into a load resistor. In addition, the Windy Boy Protection Box features a 3-phase rectifier. It is delivered as a turnkey unit and can be used with nearly all types of generators from various manufacturers and with different power classes. This makes the Windy Boy Protection Box the optimal solution for wind power plants, but it also provides the perfect link between permanent magnet generators and the inverter.
CODE: Windy Boy 1100LV
The solution for low generator voltage
The Windy Boy 1100LV is the perfect solution for small wind power plants with low generator voltage: Turbines with 24 or 48 V nominal voltage can be connected without an additional voltage transformer. The programmable MPP characteristic curve offers the greatest possible freedom for choosing the turbine, while the weather-proof casing and the wide temperature range allow for installation at almost any location. As an inverter for wind power plants, the Windy Boy is optimally adjusted to the frequent load changes. Its minimal internal consumption during still air increases yield even more, which can be monitored at any time on the display or any of several communication interfaces.
