I like to see poeple come up with great ideas to mount their panels, you are very cleaver and inventive. Great job. you power room is also well thought out and the wiring is clean with no messes. If you batteries are in parallel you may want to look at Victronenergy.com, download section,then Tech information, then The Wiring Unlimited Book around page 19, it shows the best configuration for parallel batteries. Great views.
