New Interesting installation [RE-wrenches]

[Jeff Oldham]

I would very much like to hear from the group as to the field experience w/Sunny Boy inverters and reliability. We have somewhere around 50 2.5 kW SMA's out there now and are finding that a good 10% of them end up getting boxed up and returned and about that same amount can be repaired in the field w/various tricks and EPROMS. Therefore we are seeing about 20% call backs. I'm not including in these numbers one larger project w/12 "Boys" on it that had a lot of site generated power quality issues, that one is understandable and working great now thanks to the super customer service and support from John and Kent.

SMA is claiming a 1-2% failure rate and that most of those are installation problems. Are we just a bunch of bozos that can't get 3 wires in and out correctly?!

Even though these numbers are high and hard to live with, it is still better than any other inverter I've used.

So, Wrenches what are your experiences? Just the numbers/precentages please, I prefer not to open a long string discussing individual problems.

thanks,

-jeff
