[RE-wrenches] Power One Aurora Inverters

[Darryl Thayer]

I have been involved with two installs,  They are working great, they have dual 
inputs and the broadest MPPT range of any inverter I have seen.  I have had no 
failure problems, and I have a friend that has experience with several and he 
reports no problems.  


They are ungrounded so you have to use PV wire exposed.  Your array disconnect 
has to open both DC lines per input, which means a four pole disconnect if you 
have two parallel strings.  (it takes a long time  to get the 4 pole disconnects 
from square D, rarely stocked)

Hi all.  Does anyone have       any experience with the Power One Aurora 
grid-tied inverters?  Any       comments on the failure rate for inverters 
manufactured in the       last year or two?

Thanks.
