Interesting thread topic & premise; I had to go hunting for it
nevertheless it is good to see that there aren't a litany of horror stories
Having said that, my CMS 2000 inverter "died" last Sunday, (early afternoon), having sent a respectable 5kWh to the grid during the morning. No error message, no lights - absolutely nothing; nor were there any weather events, power surges or the like to cause it grief. System was installed in June and commissioned early July 2010. (12 x Solar Enertech 170 panels on 2 tracks)
I phoned Aussie Solar (installers & retail sister company of CMS) first thing Monday morning & yesterday (Tuesday) afternoon one of the staff walked me thru a simple shut down and start up exercise - nothing happened, not even a blink.
An hour later they phone back to say that a replacement inverter will be delivered around midday next Monday.
Seems a good level of customer service, and the new inverter will carry 5 year warranty from the day of install.
