We had to store our AS for a couple of months outdoors in Georgia. When we left, the charging controllers was showing that it was charging. Our batteries were at 13.8V. We had turned off everything except the "kill switch" When we got back, out batteries was only showing 7.9V. Obviously the solar system stopped charging while it was sitting in storage. After plugging into AC power, the converter charged the batteries, but the solar is not charging even on a sunny day. Our controller has a diode and fuse in line to the batteries. Any insights?
