So, DW got me a Renogy 300W system for the TT and I am scoping out the install now. The charge controller has to be mounted inside, and the way I can get the solar power cables into the rig is right down the channel above the power converter, and I have some panel space to flush mount the controller right there. Now, here's where I have a bit of a question/doubt. Installation instructions say to run the output of the charger directly to the batteries. But, a much cleaner solution would be to tie in to the main battery cables coming in to the converter. In effect, it is the same exact thing. The resistance of the existing cable to the battery would be the same as the resistance I'd gain in running the cable all the way from the solar charger to the battery (and I'd have to poke more holes in the rig to run them). Is there anything I am overlooking? Converter is a WFCO 8955. Thanks!
