Another alternative
I would set the HVD to the MAX voltage I wanted to ever see then the reconnect maybe 1/2 volt lower so the array would power the system while the inverter has the voltage drawn down a bit. Additionally leaving the temp compensation alone.
Not sure how much easier it could be to stop the temperature compensation at any temperature. Looking at the MS web site and the Temp compensation graphs is a bit easier than doing the math needed to determine the voltage change applied by the temperature compensation.
