Hi can someone at Victron please look at the accuracy of the VRM app Widget for the phone as it records a much different reading to the VRM app which is recording the wright thing.
Please see the attached pictures of both. I’ve changed what my grid meter is for but have to wait until i can put my Multiplus on to get the CT from that working but it should still record the solar correctly which is done by an ET112. Thanks in advance
The widget is a point in time. On IOS the phone decides when it will refresh, at the specific moment the data is pulled it will be accurate. VRM has its own refresh rate and they are unlikely to align.
Using this extensively myself, I haven’t the values to be off.
Hi @nickdb no mate as solar tops out at 3200 the load is accurate as it’s just shy of what the VRM is recording. the inverter is a 3kW attached image from the Solis inverter, VRM and the widget the only one that’s really off is the widget. The load part of the widget seems accurate for the Solar but the Solar part itself is well off
Here is the data amplified now there is hardly any sun everything else is in 5watts or so of the other apart from the widget app
Can you confirm where your PV inverter is installed - AC in or AC out?
Is a meter installed at alll?
PV is installed on the AC out side of the inverter if you look at the grid and the load you can see it’s putting about 15 to 20 watts on the others above. It’s using the ET112 for the PV and another ET112 for Grid side it’s now 2100 at night and it’s still thinking it’s getting 669watts but the VRM is accurate just not the widget
Hi @Daza,
It looks like the inverter is not properly communicating with the rest of the system. It is showing as 'off' in all the photos.
The way the system calculates loads, AC PV, and grid depends on those inverter readings. You will need to get that inverter back online for these readings to work properly.
@Guy Stewart (Victron Community Manager) hi Guy thanks, yes I’ve not commissioned it yet thought I would do all the monitoring stuff and then get to that last, I just assumed because the app and the GX gave the correct readings that would too, now you say has to be read by the Multiplus2, I’m using the Multiplus2 CT to monitor a circuit which I don’t want it to adjust for I just want to see it as an AC meter so are you saying that I can’t do this also as the Victron multiplus2 needs to see everything in order to do the right calculation for the widgets?
I will ask the VRM team to have a look, but it is a known limitation that without a Victron inverter the calculated totals from energy meters do not behave as expected.
There is a section here about it in the energy meter manual -
