Solar controllers

Does anyone use the Bluesky 2000E controller? Supposedly MPPT technology improves the draw from the solar panel(s). I wonder if this is real or if it's hype.

I'm thinking about one 110 Mitsubishi panel with the Bluesky controller and two Trojan 105 batteries. I just want the lights and the furnace fan to work as needed. Not much more than that.
