One of my goals in this coach is to have a full N+1 redundancy plan for every system. As I'm working on this I'm trying to figure the best way to switch my DC loads from battery to AC power.
I'm not sure what will happen if I turn on an ac to DC adapter (like the meanwell) while I have my 12v battery system connected. I'm assuming since it's just over 12V (adjustable) it wouldn't do anything and just sit there idle unless my 12v loads drop under actual 12v.
For now I'm just going to run my 48v devices off AC but eventually I'd want to do the same with my 48v lithium batteries.
Also my poe switch and my pepwave router have dual power inputs and both support 12 to 56v. If 12v mode either isn't POE but I'm curious on how I can wire this up to use both the 12v system as well as my 48v system.
So in short I'm looking for redundancy so either 12v source can power the devices with some form of auto transfer switch or something. For now I can just use the switches on the power strip but it'll still backfeed to my batteries. I'm thinking I need to use diodes everywhere and just make sure all power flow is one way. I'm surprised there aren't fuse panels and tons of other devices with built in diodes. I did notice that my Prevost electric bay has a ton of diodes so it uses them for everything.
Don't judge my panel it's a work in progress, still waiting on relays and fuses and more wiring
