Looking at my VRM screen I can see positive and negative energy going to the grid, last night it was low values 50/60W today it is -800/-860 W fluctuating Confused is me. DOUBLY SO when I tripped the CB that feeds AC-IN from the grid and this continued 
The grid is now being fed -981W AND rather sadly my Octopus Mini says I have used energy
AND my solar is running all the AC Loads AND charging the batteries what is going on here?
DO I need to disconnect the Grid from AC-IN to stop my smart meter registering this negative energy as energy used
Some kind of wiring loop? This should be impossible.
If you switch to inverter only what happens?
This looks like a VRM Software Glitch
The Touch 70 and the VRM DON’T AGREE
Here are pictures of the VRM on my phone and the remote console on top of that
VRM says -428W and the Touch 70 and the Remote Console say 0W
Looked at my smart meter and IT does not seem to be changing however the Octopus Mini which is connected to the smart meter and is supposed to be accurate is telling another load of lies sometimes energy used and sometimes negative energy used {generated and exported}
There is definitely a weirdness happening.
The solar is almost the same as the load… However, there is also a 500watt discharge from the battery. Where is that going?
Unless you have pretty aweful power factor even the realtime numbers do not make sense.
Do you have actual measured dc loads?
Is the grid meter on the system assigned correctly on the GX?
On the vrm screen enable details, on my own system without enabling detail, i agree it doesn’t make sense.
Once details are enabled more figures are shown, which on my system then makes sense.

OK there is NO grid meter the ET112 is connected to the solar don’t get confused or fixated on the almost matching figures on the solar and the house load. There are some trees in my two doors down neighbours garden that shade my roof mounted solar panels. Pre the winter sun coming around to line up with these trees my solar energy was way above the house loads around 800/900 W and the excess solar energy was charging the batteries. The pictures here show the batteries feeding the load and the solar taking half of that load.
THE QUESTION is why is the VRM and console figures different for the GRID? Everything else looks correct and NO power is going to the Grid as my smart meter reading has not changed. My Octopus Mini is also very confused regarding energy into my smart meter going from negative to positive in some sort of crazy random fashion.
The grid meter connected to the solar system is the one i am referring to. I have no real interest about the other ones as they are not the ones reporting to the gx or to the vrm dashboard.
On the vrm it shows a pv inverter. The remote console shows solar, but i do not know if that is dc coupled or ac coupled.pv.
When there is ‘confusion’ in energy metering in a solar system, somtimes it is often because of how the energy meter attached to the GX is assigned or was assigned incorrectly in the GX. So what role is the energy meter assigned to and has its position been assigned correctly?
And i was not concerned about the load matching the solar, i was questioning where the battery is discharging to if the solar is actually matching the ac loads? It is a fairly large figure from the battery considering your ac loads are not that high.
Negative on battery figures usually means discharging not charging. And the system is self labelled as discharging. (Not charging)
AND my solar is running all the AC Loads AND charging the batteries what is going on here?
There is NO picture of the system when the solar energy was way above the loads and was charging the batteries with AC Loads showing as 0W
IF it is sunny and cloudless tomorrow and the solar energy is in excess of the loads I will take some pictures of that situation
It is a Grid connected Solar Edge FIT System with the ET112 in that circuit (previously the solar reading was a minus figure so I reversed the wires that the ET112 was using to measure the current flowing from the solar going into the FIT meter and then onto the Grid
Is your ac pv on the ac in or on the ac out of the inverter.
The weird readings are probably a software position assignment problem so unless you can explain and show how the meter is set up on the gx there can be no real help from the forum here.

From this description then this looks correct. The ac pv is feeding grid and then the battery is discharging to loads on the ac output of the inverter. Which could mean in ess the min soc is set lower?
Again i can only guess.
For any one to help we need to know 2 things to start.
- Where is the grid meter assigned and does it match your physical set up?
- What are the gx ess settings.
How is your ess set up
As in other posts, i feel a schematic drawing would negate all in assuming your descriptions and may indicate your multiple ongoing issues / allow for advice to be given.
Its not hard to simply draw system out onto paper, showing all confections / positions of equipment ect.
