<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:arial,helvetica,sans-serif;font-size:12pt">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. <br> 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. <br> 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.<br><div> </div>Nick Soleil<br>Project Manager<br>Advanced Alternative Energy Solutions, LLC<br>PO Box 657<br>Petaluma, CA 94953<br>Cell: 707-321-2937<br>Office: 707-789-9537<br>Fax: 707-769-9037<div><br></div><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><font face="Tahoma" size="2"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Marco Mangelsdorf <marco@pvthawaii.com><br><b><span style="font-weight: bold;">To:</span></b> RE-wrenches <re-wrenches@lists.re-wrenches.org><br><b><span style="font-weight: bold;">Sent:</span></b> Mon, June 7, 2010 11:36:18 AM<br><b><span style="font-weight: bold;">Subject:</span></b> [RE-wrenches] GT 3.0 FAILURES<br></font><br>
