LY, ISTR the buck converters in MPPT solar controllers need the input voltage to be 1 volt higher than the battery voltage at the output or nothing will happen.  Not sure that is the same thing though.
I will try to find that reference.
EDIT My two MPPTs just say the input voltage has to be higher. Not by how much. Can't remember where I saw that 1 volt spec.
