State 107 grid not detected

Are the quattros turned on and running ?

What is the Hz reading for the quattros?

is your wiring correct ? I assume you have the fronius on the output of the Quattros. As you have stated

Are the quattros grid settings correct for an off grid setup? Eg.50hz

I guess the quattros are in 3~ configuration?

Have you measured the quattros output at the fronius where the cables enter the backing plate ?

Do you have any more information about your system ?
