OK, the BZ Products charge controller installation manual says "You
can charge a 12 volt battery from a 24 to 48 volt solar input." Does
this mean that that I can wire the HF panels in series? Parallel means
12v from each panel? 24v would be 2 panels in series? 48v would be 4
panels in series? Is this right? Is there an advantage to wiring
these panels in 24 or 48 volt configurations? It does seem to me that
the wire from the panels is pretty light weight. The installation
manual also says that the MPPT250 charge controller can take up to 12
gauge wire so thanks Steve. How should I wire these panels?
