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...

So the inverter /charger stays 12v powered so it can run the pass through by getting that 12v from the batteries which are being cycled. If you need more 120v than the pass-through has, you get inverter help with the hybrid. Pretty neat!
I was thinking you could clamp a small float charger on the inverter/charger's DC terminals to keep it powered up and just isolate the LFPs, not floating them. If you did that with solar it wouldn't work at night.
If you had a separate inverter and a converter, instead of an inverter/charger, you would not have this. The converter would supply the 12v with LFPs isolated, not floating.
I don't know if there is much penalty in cycles or whatever if you did float the LFPs, but it would be good to have the choice I guess.
EDIT--if the inverter/charger has a "no float" option and the charger turns off, how does the inverter stay powered up? You want the battery to not float but that would put a drain on it ?
