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.
Maximum flexibility for the applications of tomorrow.
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. The high system voltage, wide input voltage range and two MPP trackers ensure maximum flexibility in system design. The standard interface to the internet via WLAN or Ethernet and the ease of integration of third-party components make the Fronius Symo one of the most communicative inverters on the market.
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.
