Solar wiring question

Do you guys even read the actual question by the OP ??

I'll admit, I sort of wondered the same thing, but the answers were all relevant.

Reading between the lines, the OP has batteries at one end and the converter/charger and solar controller at the other end of the
RV. I think he was asking whether it was OK to keep the solar controller far from the batteries and connect the output of the solar controller to the output of the converter/charger and use the existing heavy duty cables that run from the converter/charger to the batteries to carry the current from his solar controller to the batteries.

I took the answer by BFL "Yes, the converter and controller outputs should be in parallel on the batteries. Wrong to have the converter output go to the controller's input "to be a typo and he meant to say that it is "Wrong to have the converter output go to the controller's output (not input)"

I'm not particularly comfortable providing advice on this, as I don't have solar. Nonetheless, if the cables from the converter are really heavy gauge, I don't see much harm to this. I'd expect that the converter will usually be off when charging with solar, and if not, the solar isn't all that critical. It would be better to have short fat cables for both and to have them separate, but perhaps it's not practical.
