Hi,
I have an ESS setup where the original consumer unit has been replaced with a primary CU to serve non-maintained loads such as electric shower, range cooker, EV charger and the Multiplus-II 48/5000 via AC-In. I then have a secondary CU, powered from AC-Out1 which serves all the other house loads as maintained loads.
I have a Victron external CT clamp around the main meter tails to sense grid power, mainly because I know this is the best way to get fast response to ramp up/down and therefore to maintain a given grid set point.
This setup works fine but on the VRM dashboard and remote console I only see a single value for "AC Loads" which is a combination of the loads from the primary and secondary CUs. What I would like to see is separate values for unmaintained and maintained loads.
So, I decided to add an ET112 inside the secondary consumer unit to measure the maintained loads directly, expecting that this would show up in VRM and the console but it doesn't. This is probably because I have the ET112 set to the "AC load" role which it says in the Cerbo GX manual is only for monitoring purposes. I can read the data from the ET112 via the advanced section in VRM and it's still useful to be able to do that but would be much better if I could see the loads split graphically in the main dashboard or console.
I'm pretty sure I could get it to work the way I want by ditching the external CT clamp and moving the ET112 to the primary CU but then I'd lose the fast response of the grid set point.
Any other way I can get this working the way I want? Any chance Victron's software team might make this topology a supported option to discriminate between maintained and unmaintained loads in the user interface?
Many thanks, Craig.
