The Sunny Boy inverter (without WiFi) ensures maximum solar energy yields in households. Extremely lightweight design makes it easy to assemble the device. For specific conditions on the roof, e.g. shading, you can easily add power optimizers of TS4-R modules. Use of excess energy by dynamically limiting active power. Higher energy yield without assembly work thanks to the integrated SMA ShadeFix shading management. The compact inverter allows installation by 1 person.
