Which reminds me. I'm giving these solar panels and 48v power supplies to
youth groups to teach about solar. When I google for "safe" low voltage,
there seems to be all kinds of standards. Some as high as 60v, others say
50v, some say 30v AC, and of course bell circuits all use 24vac.
It seems that the 48 Voc DC solar panel inherently current limited to 600 ma
(current relates to safety of HOT conductors, voltage is the shock issue)...
is not a suable issue...(?)
