I have a pair of 12v 100ah deep cycle AGM's under my van with 3 x 100w panels in series connected to a 100/30. Camping for 3 days in total shade depleted 50AH from my 80AH self imposed limit. Using the BT app I'm seeing almost 60v solar but only 1.6A solar and the battery amps are only 2.5A with no load. If I turn on my Dometic 50qt fridge, the BT app shows voltage dropping from mid 50s to 30s with solar amps going from .3A to 1.6A. Is this normal behavior? Three days later in bulk for 11+ hours daily I've only recovered 40ah of my depletion.
