That system on the rear overhead wall of you’re bus looks great. Nice job. I like having the system visible and accessible like that. Is it finished? What would you change if you built it again?
Did you stay with 12 volt or go with 24 or 48 volt.
I’m interested in the combination load center panel. Where did you get that?
Oh, why are there two switches on the positive cable to the inverter?
Are people getting good success with the AIMS inverter?.
Thank you

And, sorry for all the questions, is there still a door behind the system. Storage there maybe? Thanks

Never mind on the inverter switch question. I enlarged the picture and looked closer. That’s a interesting setup. The setup reminds me of layouts I’ve seen for yachts. Heavy investment in bus bars, switches, large cables, and good connectors.

Clean! Lots of room!

Thanks all for the kudos...

So on my bus, this rear section is isolated from the rest of the bus with a wall just forward of the rear door, (RWD bus). This section contains all the "utility" stuff, electrical, pumps, HW heater, etc, along with a little workbench and tools.

Behind the power wall is the rear deck of the bus that has the outside part of the mini split on it. Rear windows have been removed and replaced with screens. This keeps the unit outside but still protected.

Power system is almost finished, I'm adding thermal controlled exhaust fan in the ceiling and another little box below the load center that will contain logic and some other circuitry.

If I had to do it again, I'd adjust the spacing a bit.. some things are a bit cramped. I'd keep it at 12 V though.

The combination Load Center is from Amazon: WFCO-WF-8930-WF-8950-ULTRA-Distribution

I'm having no problems with the AIMS inverter. it's been running the mini-split for about a year now.

I made my own bus bars from 3/16" copper bar and 3/8" stainless bolts.

Cables are really oversized a bit. 3/0 and 4/0 for the batteries and inverter connections.. They don't get warm..

I've run my welder on solar and the inverter with no problem.

oh, here's a shot of the AC in the rear deck space. I built out a complete galvanized steel enclosure for the deck first.. The deck is sloped and has drain holes in the corners.
