Guidance for plug in solar for Electricians

Alan B

We are now a few days from plug in solar being legal. The likes of Martin Lewis is recommending people should ask an electrician to check their installation before plugging a solar system in.

I have seen various comments referring back to changes in the law and changes to the specification for a 13A plug.

But I haven't seen any guidance from IET, NAPIT or NICEIC for electricians stating under what conditions it's acceptable to plug one of these systems in.

Personally as it stands today based on what I have seen I would not be willing to say iny installation is acceptable unless it was a single socket on it's own circuit protected by a bidirectional type A RCBO. Which I am sure isn't what the government wants.

Have I missed something, is something in the pipline?

I know lots of people will just do it, but in those situations I am not responsible.

    In respect of the MC 4 Type plugs and sockets are connectors so should comply with BS EN 62852: 2015+A1 2020 or BS EN 62852 in accordance with 712. 526.10 for fixed installtions.

    As for marking if the item that needs marking is to small the indication of compliance can  go on a data sheet or packaging for the item in question.

    It is unlikely that CE marking would apply because that is the European standard and these plug in solar devices will need to comply with the DZNEZ interim standard.

    The ENA have issued an updated G98 standard that now includes plug in solar, I am waiting for my copy to be sent to  me. Not having seen the updated standard I am thinking these new plug in solar inverters will need to be type tested for compliance with the new G98?

    No need to wait The August version of the G98 and much other updated Dcode stuff can be downloaded by anyone right now. 
    Head over to https://www.ena-eng.org/ena-docs/index  and login, or if you dont have an account register, then login.
    Once logged in click on the Dcode header and add to basket as many free docs as you wish to read, My choices are highlighted here, yours may differ. 

    As those ones are free, when you head to ' view  basket' then confirm order and so on, they will be emailed to you  for free, after about a 5 min delay in my experience.  




    The new bit of G98 is mostly in the  annex. but odd references elsewhere 



    example.

    I suggest anyone interested takes a look at the actual document, there is a lot of misleading twaddle on some parts of the web at the moment.

    There is also a new "B2" form to be used to register new plug in systems, and a new unplugging form as well, the install form looks like the old B form, but removed the installer section and currently has a 'no more than one Plug-in Micro-generator is connected in my premises' clause, but I do wonder if that may well vanish or be replaced with 'per circuit'  in future updates to align with the DENZ guidance.
