Deye is sending to grid even if Solar Sell is set to disabled

[largan]

I have a Deye sun-8k-sg01lp1-eu.
The problem is that it sends to the grid even though the option Solar Sell is disabled and System Work mode is set to "Zero Export to CT".

This behavior is observed only when the battery is at 100%. If the battery is under 100% is it not sending to grid.

These are the settings I have



and this is the Flow chart



What might be the problem here?

Is your CT correctly installed?

CT being the wrong way round could be your issue here.

Been extensively reading the manual for planning my next home system so no actual experience but here's what it says. Weird because I've always fitted CT meters on the neutral.
