Not sure what all that THHN is about, care to explain? I looked it up and it says that it refers to the type of wire I am using. I can tell you that all the wires connected directly to the batteries are from 24v power wheelchairs so I would hope that they are the right type. Or is it the unshielding that you are referring to as the problem? If so, what would you suggest? Where is the danger I have to fix for my insurance rep?
Tripping over the wires shouldn't be a problem, all of them are stuck against walls or under furniture expect for the ones directly from the panels to the charge controller. Those ones are connected with quick connects, so in the off-chance that I did trip over them, (HIGHLY unlikly since I have to crawl into that little space) they would disconnect from the controller, causing no damage to the electronics.

THHN T= Dry only HH= high heat N=thermoplastic sheathing of course, there can be other designations on "romex" also. like NM probably the cheapest, dry only plastic wrapped. The letter designation and class determines what it is suitable for, and that is way too long for a short post.
The 120 side of any RE system is covered by codes in the united states, just like any other 120 system. If you do not comply with those codes, and something does go wrong...well it is your liability and not your insurance companies.
Low power wiring, does not have these requirements as the shock possibilities are lower.
Basically you have to look at safety issues, is someone that doesn't know about my setup going to trip over it? Is the dog going to chew through the wires? Are my contacts well made? Is it neat? will water damage connections? are my wire sizes sufficient enough to handle the amperage that will pass through them? Do i have the wires protected by a proper size fuse? If i drop a piece of metal, will it short things out?
Spending money on good components, and then not doing the best to protect them from damage, or failure is not too smart , in my book.
