This is a picture of the very excellent Solar Boost 2000e at 9:00 in the morning, after a night of using the lights, stereo, and of course the refrigerator, cycling as needed to maintain the proper temperature.  The combination of the Batteries, Solar panels and the regulator that I installed, continues to exceed all of my calculated charging/usage profiles.  Best of all, when not cruising the solar panels and support rods/mounting hardware can be removed and stored in less than an hours time.   This regulator is still set at the factory default.  I haven't yet taken the time to optimize it for my panels and batteries... will get to that in the next week or so.
