Jason, My guess is that this will work just fine. My comment is that according to my conversations with Enphase, they would consider this an "off-grid" application for which they do not warranty their product. If this is the case, it is something your customer should understand upfront.

_____ From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Jason Szumlanski Sent: Tuesday, May 03, 2011 6:18 AM To: RE-wrenches Subject: [RE-wrenches] AC Coupling Xantrex XW Inverters to EnphaseMicroinverters I read the application note here: http://www.global-download.schneider-electric.com/852577A4005D7372/all/8FA29 D94B918A0FB8525781F0072FCA7/$File/ac-coupling-app-note(976-0240-01-01_rev-a) .pdf .and I contacted Xantrex to make sure the application note applies to other brands of grid-tie inverters. It does according to the rep I spoke with. I just wanted to find out if there is any real world experience out there with Enphase and the XW series AC coupled. I have a customer with three XW4024's in single phase configuration set up as a battery backup only now. He wants to add up to 10kW. I suggested Enphase as an AC coupled system (mainly due to the distance to the proposed array). I'm aware of the pitfalls noted in the application note regarding high limit shutoffs. Any thoughts?
