2003 Fleetwood Bounder 35R small solar panel on top of the front AC unit

[Sandmaniac]

Hello everyone!
So a tad over a year ago in May of 2023 I purchased a 2003 W22 8.1/Allison Bounder 35R that's literally in MINT condition outside and inside with only 22K original miles, my guess is she must have been garaged or covered, but anyhow, I noticed this small solar panel on top of the front AC and so I figure it's for battery charge up-keep. I live in California's High Desert which means tons of sun all the time; however, not once have I seen/noticed that tiny red LED on the front AC pickup be "ON". So I've heard mention that this "solar panel" maintains the batteries through something called a "BCC" and so first, does this "BCC" stand for, something like "Battery Charge Controller" perhaps? so, what does this BCC look like and where is it located, lastly, ive alsonheard of a "3-amp fuse" for this system, so is this fuse located at the braker/fuse panel above that "work station/small desk" in the bedroom or, is it in the fuse box right behind the hood on the driver's side of the coach?...thanks in advance guys!!..

BCC = battery control center. It is a black box, maybe about 10 x 10, located not far from the house batteries. The small solar panel on top of the AC shroud provides a trickle charge to the engine battery. Can't remember where the fuse is located. You might find info on the REV website using your VIN.
