Solar PV systems

[GCE]

A lot of information to process in a weekend ... one thing for sure is the sans 10142 is lacking information ... fortunately getting hands on all the other drafts in the pipe line it will assist to guide me into the new year.

Anyone have a list of the latest standards required for solar installations.

SANS 10142-1 (ed 3.01)

NRS 097-2-1-2017 (which ones are relevant ... I see there are a few)

Hi

SANS have published SANS 10142-1-2
The wiring of premises
Part 1-2: Additional special requirements for
low voltage small scale embedded generator
installations connected to THE GRID
This document was approved for publication in November 2021.

The scope of the document appears to contradict itself.


1 Scope
1.1 This standard covers special requirements in addition to SANS 10142-1 for electrical installation
of Small Scale Embedded Generators (SSEGs) rated up to 1 000 kVA intended to supply all or part
of an installation with nominal voltages not exceeding 1 kV AC or 1,5 kV DC.
1.2 This document is applicable to SSEG installations intended to be connected in parallel to an
electrical supply grid or electrical supply authority.
1.3 This document also applies to the installation of the following:
a) Solar PV installations;
b) Energy storage systems;
c) Inverter-based generation;
d) Synchronous generators;
e) Asynchronous/induction generators; and
f) Any combination of the above that are connected to a single point of supply.
NOTE 1 In this standard, the terms Small Scale Embedded Generator (SSEG) and Embedded Generator (EG)
are used interchangeably.
NOTE 2 Embedded generation is also known as Grid tied generation.
1.4 This part of SANS 10142 does not apply to
a) all alternative supplies e.g. Solar PV systems, wind turbines which is covered in 7.12 of
SANS 10142-1: 2021, and
b) stand-alone electrical generating systems.

I found this draft ... has this been published ?

Ya i am confused now, is it published or draft ? but also thanks for sharing and sparking more on this convo

It does contradict itself, says applies to solar pv then last paragraph states it does not apply... they setting them selves up for another 1000 bucks on Amendemmt 1....

We get dragged by the heals in court and clients when get something wrong yet they release a document with more questions than answers ...

Side note I have not been dragged but many an electrician has been brought over the coals when shit hits the fan but our "law book" can have errors....

The code has been published but it is quite a bit different to the draft.

Just been having the discussion on what is covered by what. I originally thought a contradiction, but it has been pointed out that SANS10142-1 excludes alternative supply operating in parallel with the main supply to an installation.( 7.12.1.1 note 2 )

Sans 10142-1-2 is for systems running in parallel , typical gridtie systems or running generators in sync with supply

[Dylboy]

Ahhh I see GCE, thank you for this.

I feel now not much of great use as I do backup and no grid syncing. However may still be a good read as in the future PV systems can backfeed once all that is ironed out and I understand the process.

so on the Christmas wishlist then haha.

It appears that the above document has now been removed from the SANS Store for purchase
Nobody appears to have been informed that the document was going to be withdrawn , but there again , nobody was aware that it was due to be published before a final round of objections and comments were sorted out
Will keep an eye out for further developments
