Here is my setup. I feel mostly confident about most of it. However, I've added an aims converter to charge my "floating" system when at campgrounds through the campground power pedestal. I will plug the converter into the shore power but the 12 volt side is permently wired into the main solar system I've made. Do I fuse the 12 volt side of the converter at the battery? It's a 75amp aims converter. I was going to tie a fuse onto the main 250amp fuse that feeds into the bus bar distributor. Can I run this on shore power and charge my lifepo4 batteries with solar at same time? My solar mppt is maxed at 50amp and converter is 75amp. The battery I will use can handle that much charging current. But does it work this way? Also I grounded the converter into the common ground on the lynx distributor that also grounds the inverter, mppt and DC to dc converter(alternator) I think. They all then go to 1 bolted grounding to chassis. I have no idea why these are grounded to chassis but I did it per instructions. Did I do this right?
