I have this instalation where an existing Fronius Primo 12.5-1 was installed, it has L1 and L2 connected which come from the grid. I installed 2 Victron Quattros 10kva to support the entire house but I just can’t seem to get the correct readings on this system. Last thing I did was buy a Victron Meter to sense the current the system is using, but still having many issues setting this up. I made a drawing of the system if there is something wrong can you please tell me? In the PV settings I have the Fronius on the AC IN 1, and the phase I’m using the “Split-phase (L1+L2)” setting. When setup like that the Fronius dissapears from VRM. Is there something wrong with the connections? This is my second installation and I am having a hard time setting this right. Thanks for the help!
