Fronius Symo

Maximum flexibility for the applications of tomorrow.

With power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for every system size. Owing to the SuperFlex Design, the Fronius Symo is the perfect answer to irregularly shaped or different roof orientations. A WLAN or Ethernet internet connection as standard plus easy integration of third-party components make the Fronius Symo one of the most communicative inverters on the market. Furthermore, the meter interface permits dynamic feed-in management and a clear visualisation of consumption.

Fronius Primo

The communicative inverter for optimised energy management.

With power categories ranging from 3.0 to 8.2 kW, the Fronius Primo perfectly complements the SnapINverter generation. This single-phase, transformerless device is the ideal inverter for private households. Its innovative SuperFlex Design provides maximum flexibility in system design, while the SnapINverter mounting system makes installation and maintenance as easy as possible. The communication package included as standard with WLAN, energy management, numerous interfaces, and much more besides, makes the Fronius Primo a communicative inverter for owner-occupiers.
