    Hi,

    You posted on one of my threads about how you just leave your batteries sitting with no charging throughout the winter and that battery your set has lasted for 19 years. I was wondering if you could elaborate on that? I have a set of 8 batteries and if I want them to continue to be maintained after I'm gone for the 11 months I'm not at our cottage, it has been suggested that I tilt my roof panels to 90 degrees so that snow does not cover them. It would be so much easier if I could just leave them down and just disconnect the batteries entirely. I'm just scared to death that simply disconnecting them will let them discharge too much. Last year(the first year I brought them up) I just left them connected to some cheap Coleman battery maintained panels and they were fine but that involved disconnecting them and reconnecting them in sets of two so they are 12V. Again, kind of a pain.

    Thanks,

    Richard

      Just saw this question.

      I think you would be fine for a few months. My system typically had no charge input for about 3 months in the winter. 1! months might be pushing it. If you go this way, be sure to clean the tops of your batteries as acid salts might provide a weak path for self discharge currents. I just leave my panels connected and the charge controller takes care of the rest.
