Dometic A/C

I have a 2018 30ft classic. Does anyone know which a/c is the 13.5K btu and which one is the 15k btu? Model numbers?

Also, if I were to put a third solar panel up where would it go? I have the factory installed Zamp solar (2 80W panels with one expansion port).

Thanks in advance.

Rear bedroom is the 13.5k with heat pump - part number 641835CXX1C0

Front / midship is your 15k AC/heat pump part number 651816CXX1C0

Regarding solar panel location, well, you have lots of options on where to place your third panel if you want to fix to the roof. I have 8 100w panels up top of my 30’ international. Picture attached regarding optimal placement of panels...

Others choose to expand their systems using portable panels with separate charge controller, which are setup on the ground, and connected via the Zamp connector at your front battery box.

Thank you!

I appreciate the timely and detailed response. I'm trying to plan some upgrades. Probably not 800W.

So far, my plan is for Lithium, micro air easy start and maybe a new charge controller.
