Ac in coming from utility causes ac out to turn off when utility power comes back on. Easy solar 24/1600.
So from my understanding the AC Out trips after a power failure when the AC IN comes back on. If the RCD trips it could be a problem somewhere with your Neutral wires. Can you confirm that your neutrals on the IN and Out side are not bonded anywhere. I could imagine this could create a scenario where some current returns through the neutral and bypasses the inverter.
If this is the case i think you should make sure that their is no neutral path from the in to the out side of the inverter.
Wiring seems fine. I see no problem with both n or l.
