OEM roof connector can be changed, re-wired or abandoned altogether.
Likely #12 wire factory-installed.
5 choices then:
run 2 panels,
change wire to #10 and run 3 panels,
change both connector and wire (#10 again) and run 3 panels,
abandon connector and wire, run your own MC4 #10 through fridge vent without connector, uninterrupted all the way to controller - with 3 panels again.
Choice #5 for those who have to have parallel panels: abandon OEM connector, install roof junction box.
Probably more solutions.
I wish they didn't install those 2-pin connectors on the roof.
