[RE-wrenches] Paralleling two PF16 batteries on Midnite AIO

[Howie Michaelson]

I've used a 10x10x24" gutter directly under AIOs and then an 18x18x4" jbox
for combining (3) PF16s with a victron combiner. Takes a fair amount of
real estate but allows for easy addition of batteries. Putting a gutter on
top of pf16s and an AIO onto of that sounds very clean but it would push
the screen pretty high and wouldn't fit in many basements.
