The grid/energy meter.
I monitor mine to see that the parallel set are happy and balanced. Not that it is doing much at the moment.
sorry i dont use a grid energy meter, do i need one?
this is my system, master phase at the bottom and the slaves above each other, i did try and get the 70mm D
C cable all the same length in each pair.
Your post at the top said your issue was the grid meter setting had changed to the inverter.
You can’t have parallel loads (in front of the inverter) without an EM or CT.
yes it defaulted to grid meter, and i changed it to invertor and it all went fine.
So you mean if i have 2 invertors on the same phase i need a CT or EM?
Where are your loads connected? AC OUT or AC IN?
yes
You are confusing me.
Do you have loads on AC OUT 1 (Critical loads) or at the input to the inverter (AC LOADS), or both?
Loads on AC in, need to be measured by a CT or EM like in your image. Loads on AC OUT do not.
The EM is a 3-phase device which is preferred for your use case.
sorry, i don’t have any critical loads, just all loads on ac out.
AC OUT is considered critical loads, ie they will be powered on grid loss.
In which case no meter is needed.
The labelling on VRM changes if you enable an EM.
Please send me screenshots of your ESS pages on the GX and the DVCC pages.
To add:
From vrm send the first 4 numerals of each serial number (after the 2 letter) and please upload the remote configuration file from vrm (it contains no personal info). Thanks
While I check the config, two things.
Disable the max charge voltage in DVCC, that is not needed, it will just confuse things.
Your inverters have age gaps, which is not good, and you have spread them across phases.
You should pair them in similar age groups (the 4 numbers are year and week of manufacture).
The youngest in a pair should be master.
Your issues are looking more like the inverters are not balanced properly, the only way to check, is with a meter under load, or using a flow like I do in node red.
I would also confirm that you can see the correct number of battery packs online in the GX pylon entry, under details.
