Now the Victron controller may have a current limiting circuit, which would be great and should not harm the controller when you very occaisonally exceed its current spec.
I think I'm fine. From Victron: " If more PV power is connected, the controller will limit input power."
So all I lose is charging output above 50 amps on the very rare occasion the panels might make that much.
