G83/2: list of inverters?

[solarcat]

Hi colleagues,

where do we find a list of inverters certified for G83/2? The time is nigh

Do not know whether such a list exists or will do. But no doubt all the manufacturers who want to sell in UK are getting the tests done or have done so already. Have a look on their websites.

I fitted a Solar Edge inverter last week which was compliant with G83/2 rather than G83/1. It has caused an exchange of emails with WPD wanting to know the type test reference. I hope I have found the right document ....

As Bruce says, there isn't (and prob won't be) a list. It's up to the manufacturer to achieve certification to a country's specific criteria/approvals etc.

If a DNO insists on certification to G83/2 (for <16A/phase) or G59/3 (>16A/phase) for inverters being used now then they're talking out of their backsides:

http://www.dcode.org.uk/assets/files/dcode-pdfs/Distribution%20Code%20v%2020.pdf

Now that G83/2 and G59/3 have been published the Distribution Code Review Panel wishes to see the following continuing interpretation:

• For all small scale embedded generation sets of up to and including 16A per phase (provided that the aggregate capacity of installed generation is less than or equal to 16A per phase), until 1 March 2014 it is permissible to connect to the general requirements of previous versions of G83 provided this is through an inverter or controller with a protection/control system that has either been fully type tested in accordance with G83/1-1, G83/2 or in accordance with G59/2. After 1 March 2014 it will only be allowable to connect small scale embedded generation of up to and including 16A per phase that complies with G83/2 (or with G59/3for small scale embedded generation sets non-compliant with G83/2).

• Connection of small scale embedded generation of above 16A per phase (including the connection of small scale embedded generation of less than 16A per phase where the aggregate capacity of installed generation is greater than 16A per phase) made before 1 December 2014 can be in accordance with either G59/2-1 or G59/3. Such connections made after 1 December 2014 must be made in accordance with G59/3.

Just to finish off my comment above that I had fitted my first G83/2 Solar Edge inverter, I have supplied the correct G83/2 test results to WPD which they have accepted. However WPD have issued their standard letter back saying we may connect it providing it complies with G83/1 and we have the G83/1 warning labels in place.

File and forget. Life is too short to try to put them right.
