PV system

Agree. No problem with 30mA RCD protection to AC cable if embedded in wall <50mm to comply with regs.

It is wrong to terminate the CPC through the isolator terminals rather than the fixed terminal which I suspect you will see in the rear of the isolator enclosure.

And even more disappointing the original installer hasn't offered his service to arrange a de-energise and recommission after the works have been conducted. Good customer after care/service is the seed to good business. But may be he knows whats wrong.

is that inverter outside?

Where's the Isolators for this inverter?
Twin and earth for DC into inverter? I might be wrong with this but I'm sure T&E is not allowed for DC with PV systems, >120v has to be double insulated , or maybe you can if its fused ?
Warning labels, schematics, shutdown procedure etc?

hope that installer is using this for his next Mcs visit!

if that inverter is outside i would be just as worried as the lack of everything else! That housing isn't rated for outdoor use

I was surprised at the "electrical install" side of it. I am putting the supply cable through the RCD, its my signature at the end of the cert and I shall also be writing a covering letter just to make sure my backside is not exposed......so to speak

If I were you I would move that inverter in side lable it up correctly use isolator. Also you won't be able to use an rcbo they don't work correctly eith current flowing the wrong way through then it will need to be an mcb with a rcd main switch
