MIXED PANEL ARRAY'S [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

I'm going to be testing one of these MPPT's from Solar Converters again. 
While I like their other stuff, I tried using their high power MPPT units 
last year. Designed for 48 to 200 V in, 48 V out, 60 Amps. I burned up 7 of 
them, working with Dan Pringle all along to try to figure out the problem, 
to no avail. Had to get on a three story barn roof in December to rewire 
the array to 48 V. Threw in a couple of C-40s (slightly over limit at 42 
Amps) and the system has worked fine.

Dan says he "found there was a bad batch". But I would not consider them 
"proven" yet. So I'll try one at home this time.
