Been doing similar myself with the cabling the last couple of days.
Sunsynk installer installed the AC cable to my invertor in 4mm cable through the loft to the fuseboard, and i noticed last year it was getting fairly warm and not just on sunny days when my loft is like an oven. He'd also pushed the bulk of it through the loft in the same 20mm dia trunking as the CT clamp cable. Length around 7m. Sunsynk manual (for what its worth) says min size 6mm.
Now im no electrician at all but have never been overly happy with that, its noticably warm, so have been planning to uprate the cable and finaly got it done yesterday.
Added myself an additional 20mm trunk through which the 6mm was run, as i didnt fancy pulling the old 4mm out of the existing shared trunking incase i damaged the CT cable, it was quite tight. So have left the old 4mm cable in situ in the old trunking disconected at both ends.
All now up and running on the new 6mm and 'cool to the touch'
Not the tidiest of wiring jobs but what do you expect from a plumber
That looks great, always worth reviewing the installations on a reasonably regular basis. As they are not inert and we are only human! Cool to the touch is a good place to be.
I've been gathering together my wee pile of bits for Turkish balcony micro solar installation. Made up some brackets this morning. I'll backpack out the lot mid July.
I am a big fan as we know of balcony solar.

Another plus we've not mentioned is zero need for expensive rails, clamps and brackets? As panels have dropped in price a much bigger percentage of the cost is now attributed to fixings?
I can genuinely claim that the last 6 strings (including Turkey) that I have put together have cost literally a few quid all in to mount. I'm not advocating non pro rail systems for homes but garages, outbuildings, sheds downwards are all fair game for ingenuity?
Turkish system will be fixed to the rear balcony wall with leftovers from the last diy battery bank build. I'll need to buy 16 no5 50mm stainless steel screws in Marmaris as I can't backpack sharps but that's it. The rest is Wombled or hand fabricated from my own stocks. I like that.
