[Rhodes22-list] Solar battery chargers

[Rick]

Low voltage charging of a deep cycle battery shortens the life of the
battery.  Unlike car and farm batteries, deep cycle batteries require a
minimum charging voltage to "clean" the plates.  High voltage charging has
a similar effect by loading all the charge onto the surface.

The voltage output of a solar panel varies according to sun intensity and
temperature, and it reverses at night.  I've had good luck with a Sunsei
regulator and it includes a diode in case the solar panel lacks one.

There is a sequence to connecting the battery when the panel is charging.
Since I can't remember it, I just cover the solar panel with a seat cushion
when I hook up the battery.
