Fronius Symo 3700W three-phase solar inverter for grid connection
The Fronius Symo line of pure sine wave inverters offers superior performance for residential and commercial three-phase installations. The Symo inverters stand out for using transformerless technology, internet connection via WLAN or ethernet cable integrated into the inverter without the need for additional components.
The Austrian brand's robust electronics and mechanical design make Fronius Symo inverters the best choice for reliability. Designed for long life with short-circuit, overload and high temperature protection, the Fronius Symo is a safe choice for any solar installation that wants to operate for many years. 7 year product warranty and CE certification
The Fronius solar inverter of the Symo series is a three-phase inverter (unlike its brothers Primo) for grid connection without transformer that allows the synchronization of the solar installation with the electrical grid also three-phase.
All models of the Fronius Symo series incorporate 1 MPPT's (Maximum Power Point Tracking) and have IP65 protection. The Symo Lite/Light solar inverter models do not incorporate Wlan communications for remote management and monitoring unlike the Full models of the same series. The Symo series solar inverters have a standard interface to the internet through a Wlan or Ethernet cable for easy integration. The Fronius Symo inverters include datamanager and free connection to the solarweb portal, which allows a clear and remote monitoring of the three-phase solar installation.
The Fronius Symo solar inverters have a zero grid feed-in system that allows us to reduce the inverter power to prevent energy from being fed into the grid in the event that the solar installation produces more electricity than it is consuming.
The main advantages of the Symo series of Fronius are:
