Just witnessed MPPT voltage drop below 14V
Well this is interesting. Half sunny half cloudy day, 92 degrees out. Collected this data looking at the turnigy for the maximum panel output (not max amps to battery which was fun but not any real ob...

Hi Jim,
Your results are why I chose series/parallel for my install. I think it is one reason I do get some charging in the rain. Today it will rain all day--and I have no reason to drive, so I'll survive on the battery bank's reserves. I'll only get enough to cover the parasitic drains today I fear.
I agree--a poor mppt controller can, in some circumstances do less well than pwm for nominal 12 volt panels. (17 volts).
