The Fronius Symo inverter series has been specially developed for the demands of the North American market. Available in power categories from 10 to 24 kW, the transformerless device is the perfect three-phase inverter for commercial systems of any size.

With a high system voltage, wide input voltage range and two MPP trackers, it guarantees maximum flexibility in system design. 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.

Standard equipment also includes a built-in arc detector (AFCI = Arc Fault Circuit Interrupter), in keeping with all other North American SnapINverters.
