The Xantrex panel is to turn on your inverter that I would say powers your residential fridge when you're not on shore power.
The other panel is your panel for your leveling system, awning(s), slides, etc...

That version of XANTREX remote monitor, the ones installed in 2019's, is not bluetooth enabled....XANTREX does make one that is bluetooth ... same form/fit, function, just has bluetooth and APP... I am thinking of upgrading to the newer version of the XANTREX monitor..
