Symo 12.5-3-M
Fronius Symo 12.5-3-M Inverter 3 phase
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.
