It seems all metros are using the same document.
I believe this document should be discussed in more detail, so that everyone can understands the contents and calculations.
When I enquired about registration, I was told to check to first check the guidelines. I have downloaded it but been pre occupied this week (at least we got news today) so I should be able to focus on work from today.
I went to the solar show, NERSA said go to your munic and eskom I had to explain what an electrical contractor was....
The left and right arms dont know of each other.
I went to Joburg Munic website and nothing I can find to register a system at all... Probably some stupid hidden link but I cant find it at all.

I believe part of the problem is also that most people are relying on tits and bits they "hear", instead of studying all the facts.
I know I am guilty of this, partly because I have been around long enough to know that the chances of being caught is so slim, due to the lack of man power skills and and policing.
Dug deeper and it seems City Power here in Joburg rule the roost with the registering of PV systems... Goign to phone tomorrow and email to find more info.
Intrestingly they speak of 25% of main CB for max size of inverter if grid tied.
They even say 60A main CB may not have a a system larger than 4.6 KVA...
I smiled my supplier this and some questions to see what they say... Other wise every Hybrid 5kw is illegal if they have an AC input from the Grid

Let us know what info you get.
Will be very interesting

Do we have to comply to this document ?
This document is not a South African National Standard

The utilities basically make it a Bylaw - so yes you need to comply
Felt like doing some maths.
Single phase voltage is 230V with a 10% tolerance either way, so anything from 207V to 253V is acceptable.
So 25% of 60A = 15A.
So at the lowest acceptable voltage, the power will be 207V x 15A = 3.105 Kw.
At the highest acceptable voltage, the power will be 253V x 15A = 3.795 Kw.
It will be interesting to know how they calculated it to give a result of 4.6 Kw.
230V x 80 Amps x 25% = 4.6
