Low-voltage electrical installations - Part 7-712: Requirements for special installations or locations - Photovoltaic (PV) systems
This section applies to the electrical installation of PV generator intended to supply all or part of an installation and feeding of electricity into the public grid or local distribution. In this section, the electrical equipment of a PV generator, like any other item of electrical equipment, is dealt with only so far as its selection and application in the installation is concerned. The electrical installation of a PV generator starts from a PV module or a set of PV modules connected in series with their cables, provided by the PV module manufacturer, up to the user installation or the utility supply point. Requirements of this document apply to – PV generators for supply to an installation which is not connected to a system for distribution of electricity to the public, – PV generators for supply to an installation in parallel with a system for distribution of electricity to the public, – PV generators for supply to an installation as an alternative to a system for distribution of electricity to the public, – appropriate combination of the above. Requirements for PV generators with batteries or other energy storage methods are under consideration.

Nizkonapetostne električne inštalacije - 7-712. del: Zahteve za posebne inštalacije ali lokacije - Fotonapetostni (PV) sistemi
Ta razdelek se uporablja za električno inštalacijo fotonapetostnega generatorja za napajanje celotne napeljave (ali njenega dela)
in prenos elektrike v javno omrežje ali lokalno distribucijo.
V tem razdelku je električna oprema fotonapetostnega generatorja (kot kateri koli drugi del električne opreme)
zajeta le toliko, kolikor je to povezano z njeno izbiro in uporabo v inštalaciji.
Električna inštalacija fotonapetostnega generatorja se začne pri fotonapetostnem modulu ali naboru zaporednih fotonapetostnih modulov s kabli, ki ga/jih zagotovi proizvajalec fotonapetostnih modulov, vse do uporabniške inštalacije ali točke oskrbe z napajanjem.
Zahteve tega dokumenta se uporabljajo za:
– fotonapetostne generatorje za napajanje inštalacije, ki ni povezana s sistemom za distribucijo električne energije v javnih omrežjih;
– fotonapetostne generatorje za napajanje inštalacije, vzporedno povezane s sistemom za distribucijo električne energije v javnih omrežjih;
– fotonapetostne generatorje za napajanje inštalacije kot alternative sistemu za distribucijo električne energije v javnih omrežjih;
– ustrezno kombinacijo zgoraj omenjenih možnosti.
Upoštevajo se zahteve za fotonapetostne generatorje z baterijami ali drugimi viri shranjevanja energije.

Introduction
For the purpose of this part, the requirements of HD 60364/HD 384 apply.
The Parts 7XX of HD 60364 contain particular requirements for special installations or locations which
are based on the requirements of the general parts of HD 60364 (Part 1, Part 4, Part 5 and Part 6).
These Parts 7XX have to be considered in conjunction with the requirements of the general parts.
The particular requirements of this part of HD 60364 supplement, modify or replace certain of the
requirements of the general parts of HD 60364 being valid at the time of publication of this part.
The absence of reference to the exclusion of a part or a clause of a general part means that the
corresponding clauses of the general part are applicable (undated reference).
Requirements of other Parts 7XX being relevant for installations covered by this part also apply. This
part may therefore also supplement, modify or replace certain of these requirements valid at the time
of publication of this part.
The clause numbering of this part follows the pattern and corresponding references of HD 60364. The
numbers following the particular number of this part are those of the corresponding parts, or clauses of
HD 60364 being valid at the time of publication of this part as indicated in the normative references of
this document (dated reference).
If additional requirements or explanations are needed which have no direct relation to general parts or
other Parts 7XX the numbering of such clauses are stated as 712.101, 712.102, 712.103 etc.
NOTE In the case where new or amended general parts with modified numbering were published after this
part was issued, the clause numbers referring to a general part in this Part 712 may no longer align with the latest
edition of the general part. Dated references should be observed.
