Solar wiring question
Looking to install solar on my prowler 24lz trailer. Watching and reading peoples installations it seems that the best thing is to install your charge controller near your battery and then wire direct...

I just installed 2 140W panels from Solar Blvd on my son-in-law's TH TT. I ended up removing the 4 feet long MC4 cables attached to the panels. Those cables had extremely thin wires. I used 8 awg cables for connections down to the controller.
One of the most difficult decisions is where to drop the cable through the roof. When possible, I want to avoid putting extra holes in the roof.
My first choice is the fridge vent. That didn't work because this TT did not have an intake side vent, rather the intake was through the floor.
My second choice is to go through the black tank vent. That didn't work because the vent is only 1/2" ID. The cable didn't fit.
The last choice is to drill a hole right below junction box. The best location to drop the cable was a dead zone area, right in the front of the TT. The cable is hidden from view, and it's now a short run from charge controller to batteries.
Something for the OP to think about.
BTW, regarding OP's question. The converter cable may have a long run and be higher resistance than you would want. That means solar charge will not be as efficient.
