Has anyone done it or can point me to design rules?<br><br>Why you ask…I believe the SolarEdge new 11400 Energy Hub inverter and a LG Prime 16 will provide higher backed up power and thus a larger critical load panel. I can do this in a more compact space and at less cost than three Encharge 10 batteries which would provide roughly the same peak backup power. And you ask why not just use all SolarEdge…there is a separate metal building with ample capacity electrical already run to it. By interconnecting Enphase there, I can get more PV capacity beyond just the PV with SolarEdge on the primary building without a new trench/conduit for separate DC runs from the separate building. The loads in the metal building are on-demand only so in essence this building circuit becomes primarily as PV/Enphase solar circuit (with proper utility disconnects added, of course). It’s this circuit that I’ll want to AC-couple.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any insight on AC-coupling of Enphase to SolarEdge and ratio of Ac-coupled to overall SolarEdge capacity?
