Please Could double check this for me Victron RS 450/100

This is from Yesterday - now, obviously these are operating voltages (vmp) not open circuit...but aren't even seeing a spike in the morning before the controllers start. Hope this helps.

EDIT: yesterday they were in the low 30F's and it's rare for this location to drop below 8F

Thanks Dexter,
I think I have this figured out now. I think the panel specifications I used had a slightly higher VOC than the panel you used. I am glad you pointed out that you replaced the 450/100 with the 450/200 due to being slightly over the max wattage of the controller. There is a lot to consider when designing a large system like you did for Courtney and Riley.
The Solar charge controller alone,
Over Voltage,
Over Wattage,
Over amps (not so critical I understand),
All of the above for each tracker,
All these parameters for the SCC as a whole.

Thanks for your input. Much appreciated.

You know there's a Victron calculator right?
