[ANSS-netops] PASSCAL Developed Power Management Module (Charge Conroller and Power Switcher)

[David S. Croker]

Kyle,

Thanks for sharing.  We haven't moved to MPPT charge controllers yet 
just due to the costs.  It's still hard to find a good one in the 
$200-300 range, but even then that's quite a bit cheaper than what 
Betatron is charging for all the extra packaging.  At that price I 
don't see us moving that direction at this time, but thanks again for 
sharing.  It's a nice looking unit, though.  I'll stick with my $50 
Sunsaver with LVD for now, although I can definitely see the 
advantages of MPPT for some of my extreme-weather sites.
