I am installing 2 310 AMP nominal 12 volt batteries in parallel to my 5th wheel. I am also installing 840 watts of solar panels hooked 2s then each pair running to its own EPEVER 40 Amp SCC. Given my 5th wheel is parked and charging a lot more than it is running down the batteries I am guessing the batteries will always be in a pretty decent state of charge. My Dodge Ram 3500 dually has a 30 amp fuse protecting the DC 12 volt connection to the trailer. I have isolated that hot line from the truck at the DC positive bus bar in the 5th wheel. I am tempted to install a 25 amp inline fuse in that line to introduce a point of failure at a lower amperage than will pop the truck 30 amp fuse.
If I start blowing fuses it will be readily apparent my initial assumption about the batteries being a a fairly high state of charge when the truck is hooked up will be in correct and I really do need a 20 - 25 amp max draw DC charge DC to DC charge.
What to those who know about this stuff think? Am I all screwed up in my thinking?
