Poor PV install? Advice needed

[baldelectrician]

We carry out wiring checks for rental properties

We have just carried out an ECIR on a bungalow which failed (no gas or water bonding)

Now, someone has installed a solar PV system without any bonding in place (132.16 anyone?)

My main question - do PV installs require a certain type of RCD?
I think the RCD has also been wired the wrong way

The installer has installed a CPN consumer unit for the PV but put a Moeller MCB inside that .

I have a feeling that I will need more info on the inverter to find out which type of RCD is required.

I provided this response to another post on Solar PV which covers earthing and bonding:

TL inverters And array frame bonding - https://www.electriciansforums.net/threads/tl-inverters-and-array-frame-bonding.185782/#post-1626875

What RCD to use should be in the inverter's literature. If you provide me with its details I will do some research.

The other aspect to consider is the requirement for pv panel and wiring and inverter output isolators and their correct location and labelling. And, the requirement to tell the DNO about this grid tied system.
