I had been looking everywhere for good 8awg PV (UL 4703) wire and that alone was difficult. Then I upped my specs and decided I not only wanted 8awg PV wire but also tinned copper and a high strand count. Found a couple/few spec sheets online, called many companies but nobody offered it anymore and said it had been 2-4 years since they last had some.
Well, I finally found some! I had to friggin order 1000' of it too, ugh! I probably only need 100'. The only downside which I had to settle for was I could only get it in black, so I'll be using this for my negative and positive runs and will just mark my positive clearly with red heat shrink or something.
This will connect my 4 large panels on top of my 43' fifth wheel. I should note that 10awg wire would've been just fine and I know that With my 4 panels in a 2s2p config I'll only be pushing a little over 20a.
Here's the spec of the wire
8awg, PV (UL 4703), tinned copper, high strand count at 168, 1 conductor.
These are the specs of my individual panels showing that I do NOT need 8awg haha
Pmax 370w
Vmpp 35.5v
Impp 10.43A
Voc 41.9v
Isc 10.96A
I did order 8awg MC4 connectors from Staubli as well but haven't received them yet so I'll have a better idea next week on the quality and fitment of those.
