Last night the house's voltage hit an all-time low for this winter of 9.9v. With a 12v system, that's getting close to dangerously low. I unplug everything when it gets down to 9.0v to avoid battery and electronics damage.

Very glad to be getting a full load of sun today, after 10 days of mostly clouds. It won't get me up to a full topped off charge, but it's a start at digging out of the winter's hole.
