While the Smart Ports on the GridBOSS can be set to AC couple, what about direct to the LOAD port on the FlexBOSS? In the video EG4 FlexBOSS21 & GridBOSS Premiere Interview: The Most Powerful Solar Solution Yet published back in November, James discusses at length how this is done and how it solves the "dark start" problem. At one point EG4 published a document on the website titled EG4 How to AC Couple on Load Port w EG4 Hybrid Inverter and GridBOSS.pdf that explains how to do it. I can't find that document online anymore, but I do have a downloaded copy.
My question is, is this still a supported and recommended configuration or should all AC coupled arrays go through a Smart Port? What are the benefits and drawbacks to each method?
