Please let the VM-3P75CT AC Load Meter be used as main load meter instead of Multi/Quattro!

I have a three phase system with a manually switched battery backup Quattro system that is only one phase. The Quattro is fed directly from the grid and a generator. The VM-3P75CT is connected to all of the loads and measures the energy being used by the loads regardless of the source (three phase grid or generator, and single phase Quattro connected to all three phases on the input). As currently connected, the VM-3P75CT is being used as a load meter, but when in load meter mode it doesn’t show up on the dashboard. If it’s configured as a grid meter, it works correctly most of the time as the Quattro is only used for extended outages, but when the Quattro is working the results are not accurate as the grid meter is apparently added to the Quattro output to show the loads in the dashboard, resulting in a doubled load figure.

What I would like to be able to do is select the AC Load meter as the measurement that shows up as the AC loads on the Cerbo GX and VRM instead of the Quattro. This seems like it should be very simple, and a similar question has been asked here. At the very least it seems like the other question should be addressed so we could see a sub-load on the dashboard.

I have same issue but with em24 meter configured as AC load.
Not visible on VRM.

It should be visible on VRM, just as a widget on the “Advanced” page. That doesn’t work for me as I want it to replace the readings from the Quattro. However there are other users who want to have a separate AC loads box on the main VRM page. I think both of those should be options, especially given the advertising claims that would make a person think it’s possible.


Here’s what it looks like in load meter mode. No data because I changed mine to “Grid Meter” mode which at least works when the power is on, which is most of the time.

Hi @KW4NP,

I am going to move this over to the VRM beta space because we are putting some work into improving the handling of Energy Meters without Multis/Quattros soon.

It might be some time before it gets responded to again, but it’s on the radar.

Following. Also interested to have an accurate output measurement visible on the dashboard.

Thanks for looking at this. I’ll be happy to test as you come out with the new firmware, please just let me know when it’s ready.

@guystewart , Any update on this issue?

Another similar question here

Another question about this here. @guystewart is there any way to see where this is on your list? I have a client who is waiting for this to happen and they are thinking about doing a major rewire to make it work the way they want if this is not going to happen soon.

This is also related, although not quite the same. This is a request to have it as a sub load, which would also be useful in my case.

I’d refer here my need/expectation regarding the EV Charging → How to make EVCS detached from Critical Loads summary?

I think, Multis/Quatros could still measure the Loads. But:

  • if we have EVCS, it should be not included in AC Loads/Critical Loads
  • if we have meters configured as loads (any role), they should be visible as separate boxes with load details
  • we have Total Consumption box, which summarise Total

In above scenario, we could have all “defined loads” (meters, evcs) displayed separately, of course depending on where they are connected (AC OUT/AC OUT2).

AC Loads, and Critical Loads boxes then should display “everything else” from the specific output of the device - like all the lights/sockets, that have no separate meter defined.

@arekp , this is a very similar problem, and I would like to see Victron make this work as might be expected. However, my case is a bit different as the Quattro will not see any loads on the output normally. The system is manually switched in the event of a blackout. I want the load meter to work much like a grid meter but on the other side of the Quattro. And grid meter mode does actually work unless the Quattro is powering the loads, in which case the measurement s duplicated. I think Victron should be flexible enough to do this, but we are waiting for them to actually do it. Or if they gave a rough idea of how it could be done then maybe some of us could work on adding that functionality.
