they make them out of steel or aluminum too, which means you can get them good and tight in the sheet metal and they will not be knocked off with tree branches, a couple of washers with rubber and the roof steel sandwiched between them would be even better to mount them in! https://www.grainger.com/product/HUB...rumbCatId=8812

I think "butt-ugly" gets a bad rap...

FWIW, I now agree with all you guys. I originally went with the fancy cable inlet, but now have reverted to a black plastic 7/8" 90 degree connector like some of you guys mentioned. I simply used the rubber washer to seal it up with, but I may add some caulking at some point. No leaks so far and we've been getting a fair amount of rain in Cali these days, so I'm pretty happy.

Why did I change my mind? Turns out the fancy cable entry didn't sit flat because that part of the roof is not flat. I originally built it up with some double backed tape and loads of caulk, but it seemed like that would be more prone to failure than the simple solution. Also, reduced my wiring from my solar panels to a single 10 gauge landscape wire which fits through the connector. The connector sits totally flat and is really simple and stealthy, even more so than the fancy inlet. Also, it's not butt-ugly contrary to my earlier posts.

If that is butt ugly I'm in real trouble.

Thanks!
some are very expensive but those are the large sizes for 1 inch or bigger cables or special uses. what we would be using are 10 to 20 dollars each. https://www.grainger.com/category/st...ecatalog/N-qqg

Not wanting to drill extra holes in the roof, I drilled two 16awg sized holes in one of the plastic caps in the front area of the roof. Fed the wires from my solar panels through, and then put a big dollop of Dicor on it. Worked great, has proven to be water tight, holes in the cap are elevated from the roof so even if the dicor somehow fails it's unlikely water could get in there.

I sealed with this stuff:

Here's my install that squeezed 2 16gauge and 2 14gauge wires through the smaller PG9 gland, and 2 10gauge and 4 14gauge wires through the larger.








I think these are quite un-butt, personally.

Did you do your wiring before or after your Aluminess rack was installed? I'm wondering how much wiring to do before Aluminess installs our rack. It's probably easier to access the roof before the rack is installed but once the rack is installed it will be easier to figure out where and how to route the wires.
