[Mr Mark Sparks]

thanks mark

That diagram has been copied from the similar decision tree in the DTI PV Installation Guide v2

It looks to contain the same information to me.

This is the original.

 

[Mr Mark Sparks]

the wording is confusing its says pme-yes-bond to electrode

or pme - no -bond to main earth

doesnt it??

 

[topquark]

PME Yes, INSTALL and bond is the way I read it.

 

[telectrix]

as i know less about PV installations than i do about open heart surgery, i won't comment.

 

[TedM]

What it is saying is this.

IF you need to bond the array frame at all then:

- if the grid supply to the premises is PME then install an earth spike and bond the array frame to the spike

- if the grid supply to the premises is NOT PME then bond the array frame to the MET

Suggest you download a copy of the DTI Guide and read the relevant section. There is a link to it in the PV Guide sticky post in this section.

I heard that bonding frames when using TL inverters was being done away with.
