 Note that although the MG50 for instance has a higher start frequency of 51Hz, there is no real drawback using the proposed value of 50.2Hz. The system will just increase the frequency until the PV inverter regulation kicks in. The value of 50.2Hz will work with a broader range of PV inverters/grid codes.

 To update earlier and/or already installed PV Inverters, contact Fronius Tech Support for the file. The required file is fro29130.upd. Which works for all snap-inverter models (Primo, Symo and Eco). There is no, and will be no, fix available for Fronius Galvos.

 Later Fronius PV-inverters support both the Fronius SolarAPI- as well as the industry standard SunSpec protocol. When SunSpec is not available the GX device cannot properly detect the properties of the PV-inverter unless it is one of a fixed list of known older models. Newer PV-inverters will then show up as Unknown, and you will not be able to configure them as 3-phase.
