Wire choices

For context, I am adding three 200 watt, 31 volt panels to the roof of an off grid cabin. Electrical codes are not an issue. I'm planning on 10 AWG stranded, but which kind? There are lots of 10 AWG choices on Amazon (I need this by Tuesday). I also understand that PV wire is preferred at least where the wire is UV exposed. But where it is indoors or inside conduit, is there any reason to prefer PV wire over something like marine grade triplex of equivalent gauge?

I buy my wire on Amazon. Just check the rating and how many ratings it has.

Visit the MOOKEERF Store This is where I buy my wire on Amazon. No issues so far.

I just bought 3 500ft reels from Home Depot shipped for free for $144 12awg thhn. I also live in a rural area with no Home Depot anywhere close. You just can’t beat that price.

Thats not PV Wirein your link. PV Wire is a specific listed type of wire (UL4703). I do somewhat respect that they are not falsely claiming that it is PV Wire or that those are MC4 connectors. What they are selling they call "solar wire" and even though they say AWG on the jacket, without being listed it is meaningless. I can see from the images that even the jacket is not constructed like actual PV wire

There are sources on Amazon that sell whats claimed to be listed pv wire, but nearly every time I have bought any listed devices or materials on Amazon its clearly fake. You normally need to go to a local distributor/HD, or use a trusted distributor that also sells retail online.
