I tackle this sort of work frequently, as I only work off the grid and mostly deal with smaller systems for cabins, fishing and hunting lodges, and such, often for land buyers/sellers, Realtors, and insurance agents. By far the most common violation I see out in the bush is lack of a vented battery enclosure and lack of conduit and enclosures, as shown here. Obviously a very detailed system report is in order, and a big caveat about those batteries; they don't look well-cared for. The Midnite breaker panel is a keeper, enclosure for the charge controller, some flex conduit all around and a Midnite Mini DC box with breaker would give the shunt a home and neaten things up quickly. Then after commissioning I'd stick some data acquisition on it to get a feel for those batteries. >From my perspective, this is a pretty typical situation in remote areas, and would take less than a day's work to tighten up. I AM assuming that charge controller and inverter are UL listed, though.
