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