The Sunny Boy 2500’s nominal power of 2200 W can be fed to the grid over the whole input voltage range of 250 to 600 V due to a maximum current of 11 amps. Its maximum efficiency of 94 % is even higher than that of the smaller transformer-based devices of the Sunny Boy Family. The variable DC input range and the possibility to connect up to three strings with the reliable Multi-Contact connectors make any module configuration possible. These features enable the operator to freely design and implement personal needs for the solar system. However, the optimal configuration is a solar generator with an output of 2750 to 3450 W. It will accept a maximum of 3300 watts of PV power. It is designed to support solar panels in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling.
