Jon are you sure you have the Import and Export the right way round? Looks to me as though in you second picture it is exporting not importing?
Yep. It's two different inverters - L2 and L3. It just so happened one was importing and one exporting (here in the Algarve, currently at 41 degrees).
Edit - I see what you mean now. In the second set, charging has gone from 1.4kW down to 1kW with still constant sun and no measuring by CT. Therefore 400W is being exported.

I assumed that the display should have the same balance enterig as exiting, this appears to be the case in the first pair of photos. Not sure how the usage is determined, is it measured or just the result of a clculation on the other three?
In the second pair of photos, there is no balance any idea why - I presume I am not interpreting things correctly.
Firstly, I am not using the CTpv, so there is no reporting of generation.
The system then uses a single CT and the calculated consumption is the balance of what it has measured as import/export from the grid and what power it has sent to the battery.
The Saga continues & concludes.
There has been zero response from the DNO to any of my questions regarding the SGI-3.
I got bored of waiting so just submitted the A3.2 & G100 installation & commissioning forms filled out using my best guess.
Today I received a reply that the forms have been received & logged in their system.
So I assume all is OK.
As for the Sofar ME3000SP, there is some confusion as to G100 compliance.
It's not on the ENA register.
I have been in constant contact with Sofar tech support regarding the issue I have.
They have promised a solution/ outcome by Thursday from tech guys in China.
update: Sofar tech support have updated the firmware remotely to version 3.32.
All now appears to be operating correctly.
Disconnecting the grid ct generates an ID35 error & inverter shuts down.
