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: Reflectix taped around the box, and an ugly cover made of an old bed spread - it had some "fur" inside.

Fridge draws >34AH per 24 hrs at 75F ambient, though in defence of a cheap box I should say that the freezer bin is huge and set to -2F. Fridge set to 39F.

Fridge connects to Load terminals of Renogy,
Renogy connects to 12.8V 120AH LFP,
LFP connects to nothing, partially charged.

Busy with other things, I suddenly noticed that don't hear quiet "purr" of the fridge. MPPT is blinking "battery problem", voltage 11.

Renogy Load terminals were supposed to cut the load off at 12.6V, - they didn't.
Renogy Low-voltage alarm was supposed to sound at 12.7V, - it didn't.

Independently, darn ice box didn't cut off at 12V either - downstream from MPPT on a thin #18 cable it reads lower voltage, so LVD 12 is a-okay, only it didn't cut off.

Yeah, I know, buy Victron, I've been warned. Still curious whether I did something wrong, other than buying Renogy.

did you ever get the bluetooth dongle and get the app? I only have the porch light on my load and it works great but the only settings I saw were time based.. ill take another look at mine as the only issue I have had was with a bottle of scotch bumping into my quick disconect breaker for my battery bank. :R
