In my current setup I got 2 300W LG panels connected parallel: Voc=39.7V, Vmpp=32.5V, Impp=18.52A, Isc=19.4A for the array. My bank is 24V. After reading a few manuals for mppt controllers I got a feeling that I wouldn't really benefit a lot from getting one unless I wire the two panels in series since array voltage and battery bank voltage are not all that far apart from each other. When the manual of the Midnite Kid for example says that the controller needs the array voltage to be about 30% higher than the battery voltage to start charging, which voltage do they mean, Voc or Vmpp? (My guess is Voc, but I don't know for sure.) Would in my current setup a mppt controller then start charging at all on a cloudy day?
