I’m reading the manual of the MPPT RS and the tech specs don’t make sense to me. Can someone clarify what gauge wire the PV terminals accept? See image:
And I assume they are rising clamps which don’t require a ferrule is that correct?

MPPT RS PV input terminal wire gauge/size
Did you ever get your answer on whether or not to use ferrules? I'm about to plug 10 AWG (7-strand) PV wire into a Victron 450/200 MPPT and I'm not sure if I should use ferrules for the connection or not.
Do not use ferrules for the MPPTs.
The victron MPPT connection points use a rising clamp system that requires the cable to flatten and compress into a rectangular shape (under pressure). This provides the maximum contact area possible.
This is why it is specified to use finely stranded cables which can form the rectangle.
Thicker strands, or ferruled cables, do not compress and conform to the rectangle shape sufficiently and give insufficient contact area.
On the second row it written there, 2.5mm² to 16mm². That would be minimum size to maximum size.
