Should I run 10AWG wire (5.3mm2) to a 200W Solar Panel using only 4mm2 wires?

Hi all
I've got a single 200W solar panel that came from the factory with 2x 4mm2 wires about 3 feet long (+ and -). These wires have MC4 connectors at the end.

I'm planning to mount this panel onto a small camper van and have this question........Is it OK to run a larger wires the solar panel MC4 connectors from a Victron MPPT regulator??

Im using the Bluesea Circuit wizard using a 3% voltage drop with 37 feet round trip cable run to the MPPT solar regulator and getting 8 AWG wire which is 8.35mm2 in cross section

cheers
