In my one-phase test setup I have the usual „pages“ main screen:
there is no load connected, the displayed 12 Watts is the Multiplus II itself. AC in is not connected, the „—“ reading is correct. Adding a EM24 as PV inverter meter looks like this:
So far, so good. Setting up the EM24 in role „AC load“ and changeing the inputs that it meters consumption and not production does not show the EM24 readings in the green AC loads box. The box still shows what the Multiplus measures. ~12 Watts.
The attached load behind the EM24 is just the Cerbo, ~3.5Watts.
With an EM24 as an AC load meter present in the system, I would suspect, that it replaces the Multiplus internal measurement, as it is done with grid metering.
Is there some checkbox or setting, I’m not aware of to change the source of the AC loads display?
