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.
Windy Boy Protection Box
Optimum protection for small wind turbine systems
The Windy Boy Protection Box can do it all: It protects the inverter from excess voltage by feeding excess voltage to a load resistor, which slows down the turbine. In addition, the Box features a three-phase rectifier. It is delivered as a turnkey unit and can be used with nearly all types of arrays by different manufacturers in various performance classes. The box is thus suited for use with wind plants as well as for other permanent magnet generators such as small water power plants and CHP systems.
