during the evening with no sun available the quattro inverters only went once into passthru mode.evening.png

The issue seems to be during day when the non managed fronius is in the AC in and the gx seems to not be able to read the grid as well.

It rather seems to be a bug than a feature to me.

The Carlo Gavazzi ET112 seems to be with delayed readings. Any recommendations how to sort it? Replacing the ET112 for a new one? New cabling? Software issues?
