In that case, you need to pay attention to Voc of panels and max PV input voltage of inverter.
Your calculated Voc for the series string is at nominal 25 degrees C, but goes higher in cold weather.
You can assume up to 16% increase, so multiply Voc x 1.16 and ensure that remains under max allowed.
If that is a bit over, you can calculate using "Temperature coefficient of Voc" from PV panel data sheet, and historical record coldest temperature for your location.
Very important to never exceed max PV voltage rating at all; likely to cause failure, or at the very least be recorded by the equipment and warranty is void.
