I am adding my 280ah lithium build upgrading to a LFP converter and a new inverter to an older TT that does not have inverter capabilities. The 12v system now only powers lights, radio, and a few 12/usb outlets. These loads work under either/or converted 120v shore power or battery.
It's my understanding that if I only tie the inverter into the shore cord without proper switching then my inverter will be powering the RV converter to attempt to charge the battery as it's being drawn down to power the inverter =loop ad nauseum.
But it seems that if I follow the simple directions and use this popular switch and come into the system with the inverters 120v, at the shore cord, before the RV's converter that the same loop will exist. (I think ?)
Am I missing something about what the switch does (...or maybe even how the RV's PD4645 converter recognizes when to charge the battery from 120 shore power. That makes no sense but I've been pretty wrong more than once here.)
If this transfer switch wont stop that loop, what do I need to do it automatically? or should I just put a ton of manual switching in (ugh)?
The battery will be bulk filled from generator plugged into the shore power as needed and a portable 120W panel for top offs. (or an AIMS 75A charger running off the generator in hurried times) If that matters.
Thanks.
