In HA I have multiple sensors including energy meters.
Since adding Victron setup I observe drastically increase of untracked consumption of energy, topping up to 50% of daily usage (~5-6kWh with average 10-12 consumption)
Previously I had it around 20-25% (not everything is metered)
Can it come from AC/DC conversion? It’s there any setting i should check/change to improve ratio?
What I also observe is temperature of Multiplus when inverting. It usually is too hot to touch.
50% seems more like something is wrong on your raw-data passed to Ha.
You should review the data you are feeding Home assistant to calculate the untracked consumption. If you added the batteries DC-rate, that usually is about 10% higher than the resulting AC-consumption out of it, leading to “untracked consumption” beeing concluded, while it isn’t real consumption.
I’ve created a helper doing a battery_dc_rate * 0.9 before passing that to the HA energy widget, because HA itself does not take conversion losses into account. (But I don’t want to have conversion losses visualized as consumption, cause they aren’t )
In general I agree. I take raw data from victron meter on the grid/home edge, AC from multiplus and what is reported be SolarEdge+ meters of energy hungry devices in the home (heat pump, EV charger, oven, washing machine, dryer, lighting, it equipment). Despite of it, still 50% sounds bit too much)
