Re: 13 plus volts on rested battery?

I disconnected my solar panel controller when my boat was hauled and reconnected it for my trip down the Bay last week. In the summer, my batteries will charge to above 14 volts with the panel and the alternator. Last week, they were down in the mid 12s voltage. Is there any problem leaving them connected to the solar panel all winter?
