SMA Sunny Boy Grid-Tie Inverter

The SMA Sunny Boy inverter features several improvements over the previous generation of Sunny Boy inverters including a wider voltage input window, three independent MPPT inputs, direct smartphone access and a Secure Power Supply. The Sunny Boy inverter offers an industry-leading 100 volts DC minimum system voltage which means it will work with shorter PV strings and produce more power. The Sunny Boy includes three independent MPPT inputs which improves efficiency and design flexibility. Subarrays of panels can be installed on an East, West and South-facing roof top using the three independent MPPT inputs. The SMA Sunny Boy also includes an integrated DC disconnect switch with each inverter. The combination of three MPPT inputs, direct smartphone access and integrated DC disconnect make this one of the most cost-effective inverters available. Three MPPT inputs is especially useful for PV arrays with shading or complex roof tops with multiple sub-arrays.
