Thank you for your response. I looked into portable generator and would be able to run one air conditioner. I wouldn't expect to run it 24/7. My husband thinks the "solar prep" on the 2019 Reflection travel trailer was just to be used to charge the RV battery. My concern is can that access point be used to set up regular solar, LifePO4 batteries, invertor etc. I just haven't seen anyone with my trailer making this transformation. Thank you for all your information, very helpful!
The solar prep for most Rv’s is a single pair of #10/12 gauge run to the roof for 1 panel 200W Or equivalent. You are right it’s just a basic system to charge a house battery or something similar, not much more.
My 303Rls had solar prep, but was 2 wires connected to a small plug at the front compartment that wasn’t even connected to anything.
you can’t run a proper system on that size cable. You might be able to follow the same pathway and install a larger cable to the roof if you can find it. Your rv may have a charge controller installed from factory, and it will say what the max wattage is.
There is a thread on this site that has some good basic information to layout a plan, that you can expand a little at a time as your budget allows. It can get expensive even if you complete the install yourself, even more if you can’t. How much roof space do you have up top etc.
I haven’t installed a system on a travel trailer before, but I’m sure there is a path to the roof, you need to figure out your loads to build a system to power all your equipment.
I used instrut to mount my panels to the roof, I can then swap them out if I have issues later. I ran a conduit up to the roof with a junction box, and made my splices there.
