Nice Product
I bought a 2000E, 12 volt charge controller in May of 2005, and I must say that I like it quite a bit.
I had one scare after a few months of use when the display went blank and it wasn't charging -- but this turned out to be my foolish use of undersized wiring from three of the solar panels. It turned out that the wiring's insulation from three fifty watt solar panels melted and shorted out. (The other panel that I was using was wired intelligently, and this problem never occurred).
Before I figured out what the problem was, though, Alt. Energy Store gave me the number for Blue Sky's tech support. The fellow I talked to was very friendly and was more than happy to exchange the controller if I wanted to. Fortunately, I didn't take him up on this offer, deciding to check it out for a day or two first, and discovered it was my use of too-small-gauge wires! DUHHH!
I love the layout of the front panel, and the MPPT boost is definitely noticeable in the cooler times of the year.
In short, I would highly recommend this product!
