Allan, Check the Temps again, as far as the voltage drop from combiner box 
to CC input:.014 Vts.  The MPPT I usually do tweak a bit but Rick sends the 
units out pre set for the BP 585 current output so between us both I'm sure 
its close.

>* An extremely hot day and module temperature
>* Excessive input voltage drop
>* MPPT adjustment on the SB50 not set optimally.
>I would expect to see an input voltage of around 35 volts before temperature
