[RE-wrenches] Knockouts far from the backplane.

[Zeke Yewdall]

I noticed this on a SolArk job -- I think I bought out all of NW montana of
1" offset nipples to get 3 of them mounted to an 8" gutter once.

On the Midnite AIO's a 10" gutter is perfect to not need any offsets.  But
you can mount smaller gutters on various levels of unistrut to space them
off the wall.  An 8" gutter on standard unistrut works fairly well, and I
think you could space a 6" off with two or three levels of unistrut to get
it to line up well.  Of course then the gutter is too far from the wall to
easily mount other equipment on top of it, and it can be harder to do rear
entries into the gutter from the wall.  That's where the 10" gutter is
nicer, because it can catch the front of the inverter, as well as an AC
panel or such mounted off to the side of the inverter, and catch pass
throughs into the back of it.  I'm not sure about the SolArk and Fortress,
but I imagine they'd be pretty similar.
