300Ah LiFePO4 upgrade

I switched the solar panels from my original 2x50W parallel-wired 12V Amazon panels to the 36V 100W anti-shading BougeRV panel. the two 50W were angled to the sun with zero shade, and the 100W panel was flat on the bimini top with the mast down and shading a portion of it (I have an extension mast carrier pole that allows the cockpit enclosure to be up while the mast is down).

With the fridge ON and running, and all the cabin lights ON, and maybe 30C in the cabin: results according to the DC to DC charger app:
2x50W panels = 16.1V, 0.87A
1x100W panel = 19.7V, 1.53A

Shows how crappy Amazon panels can get after a couple of years. When the mast is up and only the backstay is shading the panel, I'm hoping things will get even better.
