SMA Windy Boy Protection Boxes

Rectifier and overvoltage protection - the Windy Boy Protection Box from SMA is multitalented: The WBP-Box limits excessive voltage and power from the generator and redirects it to a load resistor without limiting the power of your small wind energy plant. This reliably protects the inverter from high input voltages and ensures trouble-free operation. The Windy Boy Protection Box is equipped with a three-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.
