Hi,
I have the following system:
My Problem is, that whenever I have excess AC Solar and the MP2 use that to charge the battery the system counts that as “AC Load” leading to incorrect (“double”) numbers:
As far as I am aware my settings are correct:
I find similar posts to this here, but none seems to have a solution?
Any Ideas what I am doing wrong?
Thanks for the help.
To those who may find this Post in the future:
Works as intended now.

Summary: What needs to be done, is make it clear that when a CT is used with the… Multi, and the PV-inverter sits between that CT and the input of the Multi, the PV-inverter should be configured as being on the output. This either needs to be made clear in the GUI, the documentation or both. Quick TODO:
- [ ] Check that it is properly documented how to configure a PV-inverter when used with a CT instead of a grid meter.
- [ ] Make it more clear in the GUI (v2)

Set to AC Input 1

Shows on AC Out 1 (essential loads) in VRM

Should be showing on the left like in this install:

The issue is not just visual... the calculations don't add up when the energy meter is selected correctly sitting on AC Input.
For whatever reason the GX device insists it's on AC out 1, even it is not. Only when I select it's on AC out 1 (which it isn't) only then the calculations and reported values add up.
Maybe is related to the ET112 in particular. This is the only installation I have it deployed. I have ET340 and EM24 on other installations and they report just fine.
I am running 3.40~18 but I believe this is present in stable release also.
