There are 6 groups of panels (Vmp=101V, Voc=118.2V, Imp=4.18A, Isc=4.53A) connected in parallel to get a total of Imp=25AIf 101V is three panels in series, then you really need four panels in series and an MPPT as most MPPTs are buck regulators and step down.
. . . . .
The MPPT manufacturer told me that I needed 134V from the panels, in order to get 100V out of the MPPT to the battery pack.No - it's not loss. It's a buck regulator and probably about 95% efficient. The headroom is to accommodate the variations in battery and panel voltage as the temperature and state-of-charge vary.
