Ac in coming from utility causes ac out to turn off when utility power comes back on. Easy solar 24/1600.

Ac out trips when ac in is turned on. Easysolar all in one
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.
Have you tried disconnecting the loads from the inverter, testing, and then slowly adding loads on, perhaps that will help isolate the problem. If it is the RCD tripping though I am almost certain it is because your neutrals behind and infront of the inverter and RCD are bonded somewhere though.
I did turn of the ac2 out were I use it as an output from the inverter but the main ac out turned of also when ac in was switched on.
I noticed 4.5 dc amp are being used by the inverter when main ac out is turned off. Measurement done by ac clamp meter not dc. I am not sure how accurate.
