I would not recomend or consider disconecting,
bateries will always lose some charge in winter cold and may freeze..
Even in mild weather batts will lose charge over time
I leave battery conected and clean snow of my 80W solar panel to make sure batt is always fully charged..
Works perfect,,but then it does get minus 20 here..
Btw I have AGM maintanance free batt.
My GC-2 batteries stay outside all winter.
I fully charge my batteries in October then disconnect. Come April I top up the 10% charge they lost from the previous 7 months. Have been doing this for 7 years and the batteries are still going strong.
