Does condensation on solar panels delay startup of inverter

On heavy dew days overnight, I get a substantial dew on the solar panels and the inverter startup time is delayed. Seeing it more in the fall/winter months as I'm getting the sun shaded by trees more this time of year. Yesterday the inverter started up at about 8:30 am. Today it still has not started up at 9:05 am. Both have been very clear days. The inverter is seeing about 300 volts on one string and about 120 volts on the other. The bus is seeing about 300 volts. Looks like no current but don't know if that's all from the condensation but that's the only thing that has changed from day to day.

Never mind. I had a problem where the inverter grid upper voltage limit needed to be set higher.
