Thanx, its not just a switch (that is also possible with emergency switch assistant) but it shutsdown all multiplusses, disconnects the mppt’s, and shuts down the batterys as well

Reading it again, I was less than clear, sorry. When you have a number of single-phase RCDs (on the same or different phases), you must keep the N on the output side separate, or they’ll trip immediately.
So single-phase RCDs on the AC-In side won’t work as the Ns combine in the multis. Technically, it might work on the AC-Out, but it’s a bad idea.

This safety is installed in the central cabinet/distribution in the house from where the AC IN is ‘branched off’ towards the ESS that is on the pictures. I had to back track it a bit, but it is nice to be challenged this way to double check the safety.

Good news:
This weekend I replaced the 3 circuit breakers on the AC IN. I think it was both of you that suggested those might be the problem.
I could not test it properly until just yet:
I powered down the system. Combined the Neutrals from the AC OUT1 and powered it up.
After the regular startup of the multis. The NEW AC IN breakers did not trip.
Next steps is the AC OUT1 breaker to see if there indeed is nowhere a short circuit!

Because they are ONLY 2-pole miniature circuit-breakers and NOT residual current circuit-breakers inclusive … Eaton does not have this in its range
But it’s nice that it works
please mark this post as a ‘solution’ so that others can find the solution.
