Problems commissioning a Victron–Fronius installation

[emilipr (Emili)]

InstalacionSolar.pdf (133.7 KB) I have completed this solar installation. The original idea was to install the Fronius Primo 8.2 on AC-OUT, but during periods of high photovoltaic production, instability occurs, causing fluctuations in the electrical installation. I suspect this is because, when energy is being exported from this installation, the mains voltage can reach, or even exceed, 250 V. For this reason, I decided to move the connection of the Fronius Primo 8.2 to AC-IN, which prevents the Fronius inverter from having to be connected and disconnected during periods of high photovoltaic production due to frequency shifting. Among other problems, it took me a long time to configure the assistant because, with two inverters working in parallel, the assistant would not be saved unless I configured and saved it first on one inverter and then on the other. Over the next few days, I will continue checking the stability of the system. However, what I still cannot get the VictronConnect app to do is display the Fronius inverter in the correct position (AC-In), even though it is already correctly configured in the console under AC Input 1 - L1. This is while using the Fronius Smart Meter to measure the energy exported to the grid.
