Forged CE marks are a curse in many fields. I would expect plug-in PV to be neither better nor worse than many other appliances in this respect.
I don't know the rules for plug-in PV but I would hope that a suitable RCD is included as part of the inverter.
My PV at home was fitted in 2011 and certified in accordance with the regulations. I think the RCBO is a type A. Type B was all but unknown back then. There is also a problem with some RCDs and RCBOs in that they may not work correctly with reverse current flow, as you get with PV. I've read that pressing the self-test button can actually damage some RCDs.
The 30kWp PV system at the Broadcast Engineering Museum doesn't have an RCD at all. It was certified by a NAPIT approved technician. I understand that this is OK for a 3 phase system in a commercial (as against domestic) environment.
