FRONIUS SYMO 3.7-3-M

Thanks to the diverse power classes ranging from 3.0 to 8.2 kW, the three-phase inverter Fronius Symo is an excellent solution for use in installations of various sizes. The SuperFlex Design construction makes the Fronius Symo device perfectly suitable for curved or structurally diverse roofs. Easy internet connection via WLAN or Ethernet interface, as well as the possibility of seamless integration with components from other manufacturers, make the Fronius Symo inverter one of the most "communicative" devices available on the market. Additionally, thanks to the meter connection, dynamic power management and clear visualization of energy consumption are possible.
