Hello boondockers, need help wiring an either/or switch
First hello people, new to RV solar here and excited. I'm attempting to be a weekend boondocker. I have a 2013 Rockwood Ultralite 2501SS (my second TT). I read Handy Bob's blog and John Mayer's information and so much other stuff (quite a bit in this forum) I can't remember it all. To get my feet wet I have a Morningstar SS MPPT 15L with RTS (remote temp sensor) and MSC (PC Meterbus Adapter) on the way. I believe I have most of my solar system figured out with one exception. Just talked to Morningstar and absolutely positively not allowed to run charge voltage from the WFCO 8955 backwards through the SS MPPT. My brain is mush right now so maybe I have read about this but I could swear I have not seen any wiring configurations where I can have my solar power the RV and charge the battery, then have the WFCO power the RV and charge the battery. I'm thinking some kind of either/or switch with a by pass diode (can you say end around carry?). Maybe it's not that complicated.
