Smarter, Lighter, more Flexible

The Fronius Symo’s ability to communicate with the user, the PV system and the grid makes it one of the smartest inverters available. With the Fronius SnapINverter design it is also one of the lightest and easiest to install. The wide input voltage range and two MPP trackers ensure super design flexibility. Boasting power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for systems of every size.
