It has air in but has lost no pressure, happily at 2 bar which is where I left it five years hence when i last cleaned it through, so that's really odd.


I expect the guage has stuck at 2 bar. If you have air in you have 0 bar.

  Hi All,
          The reason for the question is that having in the past 6 months used so called registered qualified electricians  they have flouted their own industry bodies regulations  in the work they did.
         
           Therefore I am trying to be forearmed when I attempt to employ the next sparky to do the job properly that it is correct.

           When you pay a very good fee for a job to a registered professional you expect a proper job sadly not so in the last 3 times.

           I know there are good electricians out there but also a lot who are not but Part P registered.

               cheers

Fair comment and a situation that I know well as I have been going through the same ordeal. The things that I can add to your search are

- The 2 SMA docs that you can ref are

      http://files.sma.de/dl/7418/RCD-TI-en-43.pdf
      http://files.sma.de/dl/7418/RCD-TI-en-44.pdf

   The first one is older but details the exact inverter you have, the newer one drops the text about only certain RCDs having been tested for certain inverters and only lists newer inverters.

- Any installed inverter must be placed on its own dedicated circuit.
- As I have already noted you need to match the RCD/RCBO to the CU - it seems a good sparky would not mix and match manufacturers, but I am not sure there is an explicit rule.
- The rules state that an inverter should be treated as a 'load' so the RCD+MCB or RCBO should be at the CU end of the circuit. The risks of it being a 'source' do not seem to be considered.
- If a 30ma RCD is used for the protection it would be best for it to be dedicated to the circuit, rather than a bank of circuits. The use of a 100ma RCD/RCBO would need it to be dedicated.
- Cable size is dependent on installation, not what he had in the back of his van.

Wonder why they didn't put it on the roof of that rather large factory building in the background?

I would guess both installation cost and ownership issues as the deployed PV is owned by BP and the building is owned (or maybe even leased) by NSG. The roof is also a poor shape for PV as you can see from the following image.

      https://www.google.co.uk/maps/place/NSG+Group+Ltd/@53.5736213,-2.8152914,161m/data=!3m1!1e3!4m5!3m4!1s0x0:0x4bf39d50be20457d!8m2!3d53.572773!4d-2.8178551

Instead, BP and NSG just needed a long term 25-year agreement over some open land on the site.

It will depend on the manufacturer of your CU. While the DIN mounting rail may be a standard the live busbar configuration can differ between manufacturers and over time between CUs from the same manufacturer.

While I do not think the changing of an existing circuit is notifiable in this situation, your best bet is to use a registered electrician who can then source the correct RCD or rearrange things around an RCBO, which would be a cleaner option as you would then not also need the 2 pole MCB that is likely to currently be installed. If on the other hand, this is a new installation it is notifiable and you are likely to find that the local authorities fees are higher than the electricians.

Try here https://www.tlc-direct.co.uk/ with 100ma in the search box.

Note: I have no connections and other wholeseller's are available!

   Hi All,
      With all the talk about RCD's I wondered if anyone can recommend where to get a RCD Type B 32A 100ma or if there is such an equivalent RCBO.
      For a Sunny Boy 3600 TL21
      Have looked on the Navitron shop and cannot see one.
     

                                            cheers

                                               Richard
