    With power variants between 3.0 and 20.0 kw, the three-phase inverter without a transformer, Fronius Symo, is suitable for building photovoltaic systems of any size. The high working voltage, the wide range of input voltages, as well as the two MPP trackers, ensure maximum flexibility in creating the desired system. Through the standard interface for the Internet, via Wlan or Ethernet, the Fronius Symo inverter thus becomes one of the most innovative and "friendly" inverters on the market, in relation to the user. Also, the interface offered by Smart Meter allows monitoring consumption, as well as the amount of energy injected into the national energy system.


    Snap Inverter - represents a standardized fastening system, making installation and maintenance simpler than ever. A special feature of this equipment is that the connection area is separated from the power area of the inverter, the latter being two distinct modules, installed separately. The inverter (power module) is simply fixed in the console attached to the support. Maintenance is thus an easy process, it is not necessary to dismantle the entire inverter, the part of the connections remaining fixed.

    Integrated Data Communication – Fronius is the first manufacturer to equip its inverters with a data communication package, composed of integrated datalogging, WLAN, Ethernet, energy management, web server and a series of interfaces for user interaction. The inverter can be connected to the Internet via network cable or WLAN.

    Superflex design - represents an ingenious combination of technical features - two MPP trackers, high working voltage, wide range of input voltages. These technical attributes make it possible to obtain excellent performances throughout the duration of a sunny day, as well as in configurations with different orientations of the roof.

    Dynamic Point Management – represents an MPP tracker operating algorithm, through which it automatically identifies the optimal operating point. Its main characteristic is that it identifies the Global Maximum Power Point even in less sunny weather for an increased efficiency of the entire photovoltaic system.

    Smart Grid Ready Options – All Fronius inverters are equipped to meet the requirements of the electrical grids of the future. This provides the security of a long-term investment.

    Zero Injection into the Grid - A large part of energy operators from different countries condition the installation of a photovoltaic system on the existence of a threshold of energy injected into the national energy system. The inverter feeds the household consumers with priority, reducing the amount of injected energy, up to the limit imposed by the energy operator. This threshold can be configured through the web interface of the inverter.
