Batteries are 12VDC. Turning off all the breakers does nothing as that is all 120VAC and the converter charges.
Unless you remove all the FUSES, there will be a draw on the batteries from the radio presets, LP detector and any illuminated switch/USB charging port.
There is also little/no charge at night, so that reading may be the fully charged reading and not the “surface charge”.
At least that’s my thinking, unless somebody has a different explanation.
