SMA Wind Energy Inverters WINDY BOY Protection Box 400

The Windy Boy Protection Box can do it all: It protects the inverter from excess voltage by feeding excess generator voltage to a load resistance, 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 made by different manufacturers in various power 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.
