[RE-wrenches] Aurora & Exeltech Inverters

[Windsun@wind-sun.com]

I would add the new Exeltech grid tie inverter to that question. I see their ad in the latest HP magazine, but no info on their website about them, and no distributor seems to know much about them.

  Friends:

  Does anyone here have any experience with the Aurora inverters?  I visited their booth in Anaheim and was impressed with some of the features:

  Made in Camarillo, CA, near the Solar World plant.
  Dual MPPT inputs
  90 to 500 VDC input window.
  Transformerless (or balanced, as we would say in broadcasting) inputs
  Nema 4 case.
  Up to 97% efficient

  I am particularly intrigued with the Transformerless input.  This, IMHO is a much safer scheme.  Prior to a ground fault, no polarity is referenced to ground, reducing shock hazard significantly.  Any ground fault only references one side of the circuit to the racking and metallic structures.

  I'd like to know more.
