More fun with Renogy MPPT and LFP
Toying with a new to me 12V compressor car fridge. Cheap Chinese box, LG compressor, 50L volume split ~28L fridge, 22L freezer. The goal was to see whether my added insulation made any difference: Ref...

There seems to be a lot of confusion here.
First start with the Reflectix. What do you really expect this to do? The insulation value is very minimal. You will likely need an inch or two of good quality insulation foamboard to see any effect.
Next I am totally confused on the complaint. If the output of the panels drops below 12.6, I can understand the solar charger shutting down. I have never seen a controller which actually shut down the draw on the batteries and certainly doing so at 12.6 would make absolutely no sense. Even fully charged batteries could easily drop down to that level with just a compressor fridge and another load such as a furnace blower.
Instead it is highly likely that the compressor refrigerator/freezer has a shut down when voltage drops to somewhere around 11.0 - 11.5 volts. If that happened right away then your initial battery charge was low and/or the wiring to the refrigerator was insufficient.
