Ok so I phoned a friend ... now I am pissed off because a I stalled purchasing ed 3 ... edition 3.1 was launched 2 weeks ago and by the way apparently there are many changes in the new edition and it still doesnt include the other draft that is still in draft ...

I also need to get the NRS 097 code to understand solar installations.

I enquired about the functional earth and that kind of stuff and as usual ... its never just as simple as we think

That other draft that you shared is one of the books I can not wait to be sorted as it has a lot of information and is so useful.

7.12 Alternative supplies
NOTE Alternative supplies include but are not limited to low-voltage generating sets,
photovoltaic (PV) installations, gas generators, diesel generators, wind turbines and
hydropower plant.
7.12.1 General
7.12.1.1 Subclause 7.12 applies to an installation that incorporates
alternative supplies intended to supply, either continuously or occasionally, all
or part of the installation with the following supply arrangements:
a) supply to an installation or part of an installation which is not connected to
the main supply of a supplier;
b) supply to an installation or part of an installation as an alternative to the
main supply of a supplier; and
c) appropriate combinations of the above.
NOTE 1 Requirements of the supplier should be ascertained before any alternate
supply is installed in an installation connected to the main supply of a supplier.
NOTE 2 This part of SANS 10142 does not cover the generation plant, integration and
synchronising requirements of an alternative supply operating in parallel with the main
supply to an installation.


Grid tied or Hybrid inverter and solar systems.

The item covered in red ... something which I have noticed people are turning a blind eye ... they are aware of the consequences of the installation and the type of meter installed.

The question is going to be who will be held liable for the penalties and or investigation into the usage ... will the inspector who signed the COC be responsible or the owner using the electricity. How would they calculate the estimated usage ... will they fine you will you be liable from the date on the COC ? I dont think people signing COC's understand the implications of signing the COC.

People it is not that difficult to work out how much power you are pushing back into the grid ... especially if you have a remote monitoring system.

2 thing you gonna need to be aware of ... the date on the COC or invoice date for the installation and remote viewing data.
