22MLE Electrical Upgrade

One caveat I should have mentioned with this design is that the batteries being tied in directly at the converter means the factory battery disconnect switch in the pass-through no longer serves its original purpose. It needs to be left in the "on" position in order to feed power forward to the few items which, in the original configuration, are powered ahead of the switch. The breaker I have between the battery and converter acts as the battery disconnect, and truly kills all power to the coach while it is sitting in storage. When in use or on the road, the battery breaker and factory disconnect switch must both be on in order to power essential systems. You can decide if you like this or not.

IMO, that factory battery disconnect is more of a pain than it is useful. On my current setup, I added a true disconnect right at the battery, similar to the breaker you added. I don't even touch the original disconnect. The DIY battery that I'm currently working on will also have a disconnect right at the battery. If ever I have a need to go behind the panel where the factory one is, I will remove it.
