Am I safe to assume this is off grid? If so the charge controller does the work. If so do the calculations on panel sizing for the cold temps and try to avoid depending on the charge controller to clip any over voltage, Sooner or later failure is a possibility if you plan on the protection circuit and it fails nothing good will happen. Best to be on the safe side.

The temperature swings in my area (100 degrees F to -55 degrees F) are making me stay up hours finding inverters and modules that don't clip during the cold snowy months when it is clear. The data collection info that has been posted has been helpful, but I would like to know what designers are doing to size inverters for situations like this. Allow clipping? If so, how much is acceptable? 1kW, 2kW during those cold clear days (3 months a year here). Or is any clipping to much? Thanks everyone!
