I've never done a 2 inverter install, but am interested as to why 2 MCBs. That would require 2 meters. When we have discussed this before it was suggested to run the inverters in parallel at the isolator, then to the meter and on to a single MCB.
Looks a neat job, which, as above bodes well. there should be a second AC isolator at the DB, where you would usually also have the meter. I am guessing there is a space issue there.
6 mm cable is almost certainly fine.
The number od DC isolators suggests each array is split into 2 strings. I don't understand why they would do that. I would have thought each array to a single string to the inverter..
personally I would have gone for a single 2 MPPT inverter but thats just a matter of choice.
