LFP on Shore Power with Inverter/charger?
An inverter/charger requires that you have a battery connected (or some 12v source) so it will supply any 12v to the RV. (Unlike a converter that will do 12v with no battery) Some say not to float...

This is what I do.... right, wrong or indifferent.
I set my inverter (hybrid) to loadshare 30a or 50a depending on the power source. I turn off the charger but leave my solar on to charge if needed so the inverter is passing through power, powering everything 120v but the 12v loads are carried by the batteries. When I was doing this it was colder weather so the furnace and misc 12v loads would use roughly 10-15% DoD (50-75ah) solar would top them off and float at 13.6v. This was last spring for a couple months during covid first started and didn't want to stay in hotels for work. Also did this way 5 years ago before doing the boondocking fulltime.
Lot of cycles of use with heavy draw items everyday. Past 2 weeks with the heat (90-100f) kicking here in AZ I've been spliting run time of the generator, batteries & solar using the air conditioner. When air conditioner, tv, humidifier and other inverting loads there will be 2-3 hours of 100-175ah inverting, stopping at 60% SOC then do the gen for air conditioner for awhile longer but not using the gen to charge the batteries. By the time morning coffeemaker, microwave use is finished SOC is 40-45% and solar will charge back up by 2pm roughly when I switch the air conditioner back to batteries/ solsr and do it over again.
Today started moving north so shouldn't have to do this for a while again. :)
