Hi Jason and Christopher,
We provide installation recommendations for installing an Envoy in a separate enclosure on pages 12-16 of our IQ Planning Guide found here.<https://enphase.com/sites/default/files/downloads/support/TechBrief-Planning-for-IQ-System.pdf#page=12> This tech brief doesn't address Jason's code questions, though.

If you are using the IQ Combiner, the wiring diagram is on the inside cover. Coming from the array, L1, L2 and G. Going to the utility interconnection, L1, L2, G, N. L1, L2 into the 20a breakers, G to the G busbar, N to the N busbar. It's all there and is a nice package I think. My personal preference is to use manufacturer's equipment instead of making my own. I don't know if the AHJ would complain about non-listed equipment in the case of making your own DAS center. The Envoy may need a button pushed once in a while. I have asked customers to do this to save a trip. The Enphase "package" is safe for them to do that. I hope I did not miss your question.

The envoy itself does not have a ground connection and the only exposed metallic part is the DIN rail. I'm thinking I need to mount a ground lug in the PVC box so the circuit conductors have a ground wire in the conduit. I have always used the IQ combiner even for larger systems because it was just easier. I'm considering changing to a regular PVC junction box with just an Envoy. While on the subject, if there is ample space within a load center, would it be permissible to mount the Envoy right inside the enclosure? 400A plus load centers in residential settings often have a lot of empty space! _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org<mailto:RE-wrenches@lists.re-wrenches.org> Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm<http://www.re-wrenches.org/etiquette.htm> Check out or update participant bios: www.members.re-wrenches.org<http://www.members.re-wrenches.org>
