Hey,
1x Multiplus-II AC In (AC Out not connected), EM24 gridmeter, Fronius PV Inverter, Venus GX.
On the remote console the Multiplus AC Power is always included in the AC loads.
for example the Multi is charging the battery with 1kW and the house consumes 500W, AC Loads is 1500W. AC loads should show only the house consumption w/o the Multiplus power...?

In the given example: Are you charging the battery from grid or from solar?
And: Sure that the MP2 is connected to L1?
Hi @Lars78 ,
not 100% sure, but to my knowledge the AC Loads of the MP2 in the VRM portal (same for the remote console) is calculated using the difference between solar yield (per phase) and whatever the EM24 delivers (per phase).
So if you use L2, you will get wrong values for sure. Just simulated this here using my dbus-fronius-smartmeter setup and got wrong AC load values immediatly after exchanging L1 and L2 values.
So yes, make sure that the MP2 is connected to whatever the EM24 thinks is L1.
OTOH: It is just a calculated value for display - AFAIK it influence the stats in VRM.
OK, i´ll give it a try. But in my thinking it doesn't matter.... because it's summing 3 phase power and single phase. And the Venus knows how much power the multi is consuming, so AC Grid + PV Power - Multiplus consumption = AC loads no matters the multi is connected to L1, L2 or L3.
Happy to learn how thing work out for you. And: It does matter. If you check this forum you will find quite some posts pointing out that when the MP2 is not connected to L1, the AC load is off.
You will also have the same effect during the night, when there is no solar yield / PV power at all.
Hi, I am facing a similiar situation:
My setup is:
In the picture you can see the PV Charger charging the batterie with ~1000W.
The remaining 600W charging power come from the PV inverters.
All shown values are correct, except AC Loads:
I expect AC Loads showing the power-consumption of my house excluding the MP2.
But AC Loads shows my house consumpiton including the battery charging done by MP2.
Bye

In your assumed setup I would expect L3 to be identical for GRID and AC-Load - but it is not. Sure that all phases are passed through correctly? Any ideas where THAT mismatch does come from?
