No. This post is doubly wrong.
1) Not all solar charge controllers are reverse polarity protected, and some that claim to be aren't. One should never just connect electronics up to a circuit with unknown polarity and hope things are OK.
2) Just because a circuit is "dedicated" doesn't open the door to miss wire it. If your electrician did that in your house to say your "dedicated" electric stove circuit you'd probably lodge a complaint to the state contractor's board, and rightfully so. The color code means something. No one knows what that circuit might be used for in future. Its a code violation and an accident waiting to happen.
Electrical circuits are not that hard to work with but there are basic tools needed and guidelines to be followed. If you don't know what those are and how to do it properly then get professional help, same as you would for anything else.
OG,
1. Small charge controllers are by their nature are polarity protected. both my harbor freight and Renogy have been plugged in reversed (different rv's, wired different)
But you are correct, test first, things should ALWAYS be plugged in properly the first time, I'm just a dork.
As an electrician (40yrs, still working) I disagree.
We use marking tape to mark wires that must be used for other than their intended purpose.
(3 way and 4 way switch circuits are a prime example) also main service drops (three black wires,ones a neutral), and in my pod I have found black ,white and bare wires as ground. Never assume.
The two large wires that run under the pod from the battery to the port are all by themselves, not run with, or connected to, any other wires. and its 12v DC not 110 ac, if someone cuts or bites into it they wouldn't even know.
(Side note; there is no fuse on these wires, which scared me and I put a 30 amp fuse on it at the battery, everyone should. if this wire gets grounded somehow (cut by a rock/branch) this wire could easily cause a fire, and/or ruin a battery.)
If someone down the line is going to, find ,cut and use this wire for something other than it's intended purpose they would have know its source to turn off power to it or know what they are tapping into. properly marked this isn't an issue.
You could pull the port and swap the wires at the port, but in my opinion not necessary.
I did forget to mention in the op to mark with red/white tape.
Yes, my comfort level with wiring is WAY different than most, and you are correct, if possible always follow standards. And if you are not comfortable with wiring have a professional do it.
but some things have leeway and a dedicated 12v item like this, done properly, is still standard compliant, and safe.
cheers John
