Network inverter Fronius Symo 4.5-3-M (4.5 kW, 3 phases, 2 trackers)
MAXIMUM FLEXIBILITY FOR FUTURE APPLICATIONS.
The transformerless Fronius Symo, with power categories from 3.0 to 8.2 kW, is a three-phase inverter for any size system. Thanks to its SuperFlex design, Fronius Symo is the ideal solution for roofs with irregular shapes or different orientations. Internet connection via WLAN or Ethernet as standard, as well as easy integration of third-party components, make the Fronius Symo one of the most communicative inverters on the market. In addition, the meter interface provides dynamic power control and clear visualization of consumption.
