mppt vs pwm

Hi jrnymn,

Since all the controllers I've seen just look at battery voltage they switch out of bulk faster than one might expect. Often I see the Blue Sky change from float to bulk when clouds pass by.

I wonder if this is true of the Bogart Industries SC2030 charge controller. According to their description, it communicates with a TM-2030 to "adjust charging current based on real time battery information". Could be sales hype, but since the 2030 actually keeps track of amp hours in & out, it might be more accurate than battery voltage. Anyone have any further info on this controller?
