Hi,
My quattro installation (3x5kVA in 3-phase mode) has started to invert randomly several times a day for short periods of time.
I noticed there are other with the same behavior and they are asked to read the NS PRotection log and i have as well. and mine are empty. Last night i had the system inverting 3 times.
I am using a Ziehl UFR1002IP anti-islanding protection and the quattros are set to "Grid code Other: (not compliant to any gridcode standard)".
What are the limits for when to break grid and go into invertermode for that option, ROCOF and Vectorshift is what i'm interested in.
Is it a better option to disable LOM for the grid on the quattros and rely on the Ziehl for LOM instead?
I have recently updated my quattros from v465 to v506, and my VenusGX is on v3.10.
