Product detailsThe new Sunny Boy without transformer is the ideal solution above all for demanding PV generators and partially shaded systems. It is highly flexible in its application, high in yield and easy to handle. The high DC voltage of 750 V results in a cost benefit due to fewer parallel strings. Furthermore, thanks to the integral power supply management functions, the appliances are suitable for universal application and make a decisive contribution to mains support.
