Fronius Symo 4.5-3-M
Product Description
FRONIUS Symo 4.5-3-M
* The Fronius warranty extension applies to all new Fronius inverters up to and including 12.5 kW that will be put into service from September 1, 2023. For inverters 13 kW and above, the existing warranty models apply
With power categories ranging from 3.0 to 8.2 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.
