What do you do with the batteries in your 5er during winter? I live in Central OR and it can get pretty darn cold here at times. Do you leave them in the 5er and keep electricity to the converter or...
It isn't cold enough here (usually) to hurt well maintained batteries. I leave the batteries in the trailer and let the solar system maintain them. Occasionally, I have to brush the snow off panels. A smart charger, plugged into shore power, would do the same.
