Are all alarms and standby circuit boards isolated when using that disconnect switch? Confirm by measuring draw at the battery terminals.
I do understand unregulated 12V, and why 12V appliances are designed to accept say 11V to 15V. I didn’t understand 16.5V though, since nothing installed in my RV is rated for over 15V. But now I understand about using the battery as the regulator and it makes sense.
Yes, no phantom draw except for the battery disconnect relay. CO and LP alarms go dead, no status LEDs, etc.
I like idiot proofing. I want to be able to plug in the shore power, and not worry about if the batteries are connected or disconnected, what state of charge they are in when connecting to shore power, how long I should keep it connected, or worry about leaving it connected too long and overcharging my batteries. Thats not simple. Simple is plugging in and having it just do the right thing.
