The 100v limit is based on Voc estimated ~22v, 4 in series would be the limit.
5 x 22v = 110v.
Both the zenith and rover can be adjusted. I believe you need the BT module to adjust eq & abs time. The comet should be able to adjust with the app.
the mppt versions have current-limiting / 'clipping'. 320w in the summer could yield ~20A
from the zennith manual
? A protection feature called current-limiting mode or "clipping" is activated whenever an oversized solar array is producing power which exceeds the controller's rated output.
&
adjustment can be made in "USE" (user) battery type.
