Earlier I had self installed 23 Enphase IQ7+ inverters powered by some 345 Watt panels. When that was inspected and I received my PTO from PG&E I was ready to install my Skybox and my 48 LF280 cells which I had acquired last year. I also added 7 used Sunpower panels on a patio cover and those are DC coupled to the Skybox.
I had to do a complete main panel change out so during that process I separated my loads into two sub panels. The micros were wired to the critical loads subpanel so that they could be AC coupled to the Skybox. That way, when the grid is down. the micros can be used to power loads and charge the batteries.
Here is a picture of the Skybox and the two subpanels. Not shown are the wiring gutters I used at the top and bottom to give me flexibility and make room for a variety of CTs to measure system performance and specific loads.
