Installed very slick, one problem which a three minute call to Blue Sky Tech Support solved. If installing with a DC center (such as Outbacks') make sure the Neutral from the PV (or Combiner box) goes straight to the controller, not thru the DC Center Common neutral. Will not damage the unit, but display will not function properly.
After figuring that one out, fired up cleanly and started functioning without a glitch.
