Just about the entire lifetime production of the Xantrex GT inverters have been recalled, see the link below for details
http://www.cpsc.gov/cpscpub/prerel/prhtml11/11099.htmlAccording to Xantrex, its an issue with China produced capacitors, that when they fail, gas out combined with a spark source has caused 5 units out of 25,000 in the field to explosively have the BOS access panel blow off. There have been countless manufactures of electronic devices ( computers for example ) harmed of the past few years by similar capacitor issues, this is the first I have read where there can be an explosive outcome.
Maybe the cost saving for having things built and sourced component wise in China isn't all the saving is cracked up to be
An update , I called the 800 number and it is a simple swap out of the BOS pcb. Xantrex ships out the board for free, and you OR an installer swaps out the PCB, They are paying $250 for the first unit and $150 for each additional unit on the same site
It has nothing to do with power electronics, it all in the BOS box, there are three caps on the AC line for EMI supression, sounds like they are shorting out and causing the problems. So I'll get 400 bucks for a 2 hours work
