Yes, I have commonly found issues with the GT series. I have installed
hundreds of Xantrex inverters through the BP/Home Depot solar program.
Unfortunately, I have replaced 4 in the last 2 weeks. With so many in the
field, I am forced to spend a large amount of time troubleshooting and
replacing GTs.
On the other hand, I have also replaced 1 SB-6000U (almost out of warranty)
in the same time frame and have recently seen SMA inverters failing out of
warranty.
All in all, the Xantrex perform less reliably, but are much easier to
handle and replace, and the technical support is good. In my experience, it is
not a big difference. I trust the newer GTs more. Most of my 3.0's have been
upgraded by Xantrex to 3.3s, upon failure.

Subject: [RE-wrenches] GT 3.0 FAILURES
In my experience as well the
Xantrex GT line of inverters has been fraught with failures with one site having
three failed buggers until I had had enough and switched to a comparable SMA
product.

I am replacing some GT 3.0
multiple times. Though Xantrex pays the labor, this is still a crummy deal. My
customers really loose confidence the 2nd and 3rd time , Bad for industry and
my company.
Question, how many other
installers are experiencing multiple failures with the GT series. I have a bad
feeling that they are not addressing the engineering problems and just
replacing parts and shipping the same old problem back to the field.
