In Roof PV - Grouding?

Useful info ... looking to install Sunpower Maxeon 5 AC (fitted expanse micro inverters) in two separate strings on two separate flat roofs.

 

Came across this reasonably current Sunpower 'Safety and Installation Instructions for AC modules' dated 2021which I assume may apply to UK installs.

https://sunpower.maxeon.com/uk/sites/default/files/2021-06/Safety and Installation Instructions for AC Modules 537620 RevD Final.pdf 

 

Seems to have pretty clear advice on grounding / earthing.

 

Only question I have is whether I need to ground with separate, say copper, cable to a grounding plate / pole buried in the earth or whether I am over thinking this. Advice gratefully accepted!

 

Cheers to all
