Description
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.
Fronius Symo Small is the three phase inverter.
Fronius with headquarters in Austria has been engaged in solar electronics since 1992, in particular in the development and production of photovoltaic inverters. Thanks to solar electronics Fronius has advanced to the ranks of the worldwide leading manufacturers and continues to develop its position through ongoing product innovations. Fronius Solar Electronics stands for quality and state of the art technology to generate, convert and harness energy in a renewable way.
