[RE-wrenches] Enphase Envoy in PVC J-Box

[Christopher Warfel]

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. Chris
