Poor Solar PV Installation ??? Expert Help Needed

[SolarCity]

Having seen that second picture, it does look more like a TN-S system now.

Hi All
I am new to Solar PV Installation and have only carried out a few installations. I am like most people getting increasingly annoyed with cowboys in the trade (Electrical or Renewables). I only hope that when accreditation review time comes around the cowboys will get their just deserts. I would advise anybody who is not completely satisfied with their installation to speak to the installer's accrediting body and request an inspection.

I am using Solar Edge equipment on my installations as this system, complete with power boxes, minimises problems with shading bringing down the whole string, as the panels all operate independently and string length can be up to 25 panels on single phase installations and 50 panels on 3 phase installations.

This system is 100% safe on installation as power boxes reduce dc voltage to 1v per panel until system is paired with the inverter.

Thanks for reading my waffle - Tony

Would we still need a ground spike then, or could the panels be earthed into the earth point shown as I think that would be easier for us.

I think it's a common problem as I get non for any of the threads I'm subscribed to. Used to though.

If it's TNS like it appears to be then the earth could be taken straight back to the earth terminal shown in your photo.
