John -
Nonichris is right - there is a small inexpensive device called a charge controller that prevents overcharge. When you buy your panels, be sure you also buy a charge controller.
No, there is no master switch in the TM to cut off everything. But as long as you have a solar panel, you shouldn't need one, right?
Several of our members have installed battery cutoff switches, for storage when there is no source of power available. A SEARCH will turn them up.
