ER G83/2 2012

[ecogen]

G83/2 is due to be issued around mid March. Consultation closes this Friday 3rd.

Installers and other interested parties may wish to look at the wording in,
Master_ER_G83v5_9_Dec_2011_dcrpPC_draft
2. SCOPE.
5.1 Connection Procedure. 5.1.1 Single Connection Procedure.
5.8 Voltage Unbalance.
Appendix 1 connection procedure flow chart.
and
ER G83 - public_consultation_211211
2.8 Voltage Unbalance.

My concern is the meaning of single customers installation and
single installations.
Customers installation is defined in 4. Definitions. The electrical installation on the Customer's side of the Exit Point together with any equipment permanently connected or intended to be permanently connected thereto.

Does the word single now make these the only SSEG on a transformer or feeder?
G831/1  Annex A allows for the DNO to propose changes / reinforcements in the event that a SSEG causes operational difficulties. This was seen in part to conflict with install and notify. Annex A has been significantly revised in G83/2 with this and other sections removed or integrated elsewhere in the document.
If single does mean the only SSEG on a feeder or transformer then the installer would in effect have to contact the DNO in advance to find out if a SSEG is in commission.
4. Definitions. Close Geographic Region. 3) Has a PV installation been commissioned within 500 metres of the proposal.

It appears to be codifying in the new ER G83/2 what is already their policy in the guidance notes to G83/1.

Currently they say if you are an installer and have already installed at a particular postcode before, then you need to ask permission to install another system locally under G83/1-1 Stage 2.  If you have not installed there before then you can just do it under the normal stage 1 rules.  

5.1.1 second para seems quite clear on that - if as an installer you have installed in the more widely defined 'close geographic region' before then you have to ask.

I am feeling a little vulnerable at the moment because as my work is almost exclusively from recommendations, I have been installing for neighbours frequently and have in the rush been installing under Stage 1 arrangements when arguably I should have been invoking the Stage 2 procedure.  But no rejections yet.

The DNO  (SSE) recently said that they are happy for multiple installations (up to 6 as I recall) in the same postcode without notification. I will try and find my email.

My situation may have relevance to this thread...

I currently have no system at all, but have been planning to install 2 systems at some point, on different facing roofs of the same (single phase) house, using 2 separate inverters - thus enabling me to monitor performance of each separately and fit them as funds allow. I need to sort out any technical limitations to doing this, prior to ANY install.

I am trying to find out if there are any technical caveats or limitations for puting 2 inverters on one phase at one property? Does this come under the G83/2 to which this thread refers?

(The combined system will be over 4kW, the DNO is happy with up to 5.96kW apparently in my case.)

If they are happy then you should be ok, just aks them what connection protocol they are happy to work with.
