    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)

    Where to start ... some will say you need to go buy a power meter and connect it in your DB ... some will say a load profile ... others will say your electricity account ... my advice to customers ... your budget.

    No matter the capacity required ... at the end of the day only one thing matters .. how much are you prepared to blow on a system.

    It seems the most common setup is around a 6.6 kw panel configuration ... 5 kva Hybrid inverter and a 5.5 kwh battery.

    The question I get asked all the time ... can we start small and build on the system ... taking into consideration the budget ... then expansion.

    People are aware that EV are on their way in the not too distant future ... and we all know how that is break the bank if electricity cost keep climbing at the current rate.

    There is so much to learn... its very enjoyable but wish I started 10 years ago haha.

    Anyway one thing to research as well which I intend to do when I do the course is how and when to register a solar PV install followed by backfeeding and how and when and possibilities to do so.

    As for standards I use the two you mentioned and the draft of 10142-1-2 or whatever ever as yes ifs draft but has good info and good practices.

    And recently I learnt about the bylaws so getting those for your intended install areas but I believe you know all that already

    My post dissapeared.

    I use 4 sets of rules and regulations that all electrical work must conform to.

    1. Sans 10142
    2. Occupational health and safety act.
    3. Manufacturers specifications for consumables.
    4. Supply authority by laws.

    If anyone has more, feel free to add to the list.

    Peace out .. Derek

    Hello

    Your number 3, is it a document or just the manufactures instructions when you get the item ?

    I did a Google on the wording used and came up with other sort of things.

    Good rising brother.

    No, not one document, but everything you buy and use have specifications.

    Here's an example: https://www.voltex.co.za/wp-content/...ARTH-CABLE.pdf

    Check out the installation instructions and the note.

    Specifications do not have to be in writing.
    When a socket outlet has 4 holes for mounting it, that means the manufacturer is telling you that it should be mounted using 4 screws.

    Peace out ... Derek

    Morning !

    Ahhh yes ok I see what you mean.

    I didn't have a term for it but I try to practice looking at the documents for the products as much as possible. Some of the okes at work laugh when I ask for the instructions and the packaging but then when I say they doing something wrong and have proof I am the one laughing last.

    I started this from watching the overseas okes and speaking of manufacturing instructions and if shit had to hit the fan and it was installed with 3 screws and not 4 then they not to blame and the installer is to blame.

    But now I have a cool term to use for this "due diligence"
