Routing solar wires from roof

[David Hernandez]

I have 2020 Alpine 3400rs and planning on eventually adding solar. Question; What's the best way to route the wires down into the rig from the roof? Charge controllers and batteries will be in front bay.

Unfortunately unless your trailer is set up for it there is no best way. You will need to feed the wires down through an inside wall and along into the area you'll be putting the charge controller.
I ran mine down beside one of the tank vents closest to the battery location. Most people make a hole close by and install a cap to feed the wires into. The real problem is finding a clear path and seeing where you're pushing the wires. It can be pretty tight with lots of things,(screws) sticking into the cavity you are feeding through. You might swear a lot going though it, but you'll feel good when it's done.

I thought Keystone, beginning with the 2020 model year, pre-wired what they call Off The Grid (OTG). Doesn't your Alpine come equipped with a solar connection port on the rooftop? Or is the OTG feature just on the Cougar line?
