Hello
My Victron system uses two power meters and has a fronius PV with AC-1-out coupled.
The first power meter is on the handover point to the grid, hence its configured as role gridmeter. Needless to say that the fronius is configurd as inverter. Now comes the tricky part. Before the Victron System came I had an AC-coupled Varta Element 6 battery. This battery I still have. I wired it like the Fronius - so its coupled to AC-1-out but with the second power meter which has the role "AC Loads".
I know this is already a bit odd. Yet I have four questions, which I hope somebody can enlighten me.
1)
How does the Cerbo calculate the values I see on the remote console? The values for PV and grid seem to be valid, but AC loads is always always 0 .. 200 and "Critical Loads" seems to be all what is pulled from AC-out (of the inverter).
2)
Can the Cerbo distinguish between loads on AC1-out and loads on AC2-out? I ask because "Critical Loads" seem to be both for. Regardless if I draw power from AC1/2-out, all seems to end under "Critical Loads".
3)
Obvious question: I know the Varta Element 6 is odd man out, especially AC-out coupled, but is "AC Loads" a good role for this? Or should I go for somthing else?
4)
I tried setting the Varta Battery Meter to role "PV Inverter", yes, it added to the Fronius, but I still had "AC Loads" in the diagram. What actually is the meaning of "AC Loads", compared to "Critical Loads"?
Odd questions, for an odd system...
