Well, been on a G59 course today and to be quite honest I thought it was fairly crap. I'm not naming and shaming as that isn't the point here. The lecturer did what he could in the time and was pretty knowledgeable. One ting I thought about on the way home (hour and half drive) was the fact that although we covered a load of theory and saw some nice pictures, etc. We didn't actually cover what the process is when doing witnessed connection. I.E how far do you go with install / testing prior to DNO witness time. What is asked / required during the witnessing. What do they check etc. Can you connect everything all the way back and just leave it dead until they arrive? you get my point.

So, If anybody is board at some point; some info / enlightenment / description of your experinces, etc would be highly grateful. Some pictures wouldn't go a miss either (of PV installs not your mrs)

Also, anybody got any design plans I could look over of bigger systems so I can get a better feel for the layout etc.

Really anything will be appreciated.

Did they show you how to fill out a G59 form ? Yes

G59 is subject to areas (DNO) and you would only require a witness test and relay above a certain kW (subject to DNO) yup, explained that, usually > 50kW

If its a small G59 (normally <50kW) then you can just submit the G59 inverter details to the DNO (DNO need to be consulted) Yup, got that too

You also need DNO pre approval for connection And that

If you have to have a witness test done and a G59 relay  panel then thats specialist and you need to sub this out to be honest unless you have done a proper G59 course with witness testing built into it using the specialised equipment and either buy a decent G59 panel (no one makes these apart from me, all others are bad copies that don't comply with most panel building BS numbers) or build one yourself...... LoL, I know I need to get others to build (for quality) G59 relay box and apparently the guy who is programming it has to be there at the witness. Like I said, just not sure what can be completed up to the witness and What is the procedure while the witness is there.
