Canoe12,
This past winter I stored my Ollie outside where the solar panels could provide power to the batteries. Since I did not remove the fuses for the stereo or TV they, along with the carbon monoxide detector, were parasitic power draws. The draw was near 5 to 6 amps per day. If the solar panels were not completely covered with snow, they were restoring my batteries to full each day. Since I use AGM batteries, which are sealed, I have no concerns for adding water.
I realize many owners store their Ollies inside, but I wanted to understand more about the solar system over the winter. I also wanted to see if my Ollie was problem free during a winter season. So far, the solar system has worked incredibly well and I noticed just two minor problems. The first involved a tendency for the lock on the door (Not the deadbolt, that is fine.) to freeze. I used a special lock lubricant, recommended by John D., and the problem is resolved. I also have the black streaks from the porch light gaskets. I plan to resolve that issue in May.
For me, the winter season with Ollie outside was just a continuation of my field testing. I purchased an Ollie not just because it is well designed and well manufactured. I also believed it would be durable and hold up well to my four season New Hampshire weather. So far, I have not been disappointed!
