The VRM portal in its BETA version sums up ALL virtual meters to their value “AC-Loads” in the Sytem-Overview graph.
As my meters “overlap” (e.g. there is a general meter for the Heatpump in total, but also one for the Backup-Heater of the Heatpump alone), the AC-Load is shown way too high, as it counts some of the energy doubled.
My question (or my feature suggestion) is, to be able to configure, what Victron should use for their calculation. The current approach to just take every meter and virtual meter they can find, and sum them up, will not work for many installations I think!
Is there any documentation on what Victron does with all the meter values, and how they calculate “AC-Loads” and “Base loads” and how these values influence the system?
Recently, Victron brought the VRM-beta behaviour to the main VRM. So EVERY energy meter (virtual) is taken for something… Solar yield forecast, heating requirement, AC-Load forecast, EV-loading forecast, etc. p.p.
At the moment i did find NO solution, how to have a virtual meter at all that victron does NOT use for any calculations or statistics or forecasts! 
Even when i not fill in the ENERGY values, Victron e.g. counts Solar via the POWER over time. So it gives me no loophole at all to prevent that bevaviour.
So my setup with a lot of meters that partly counts “double” when you sum them all up (and i have that situation on Solar side, AC-Load side, Heat-Pumps side AND EV-Charger side unfortunately), is not supported by Victron. I don’t see the reason that i cannot exclude meters from VRM calculations…
Does anyone know the trick?
