It was my understanding when I read about the new SMA inverter that does PV direct to load in an outage, that it only does this within a very narrow parameter up to a max output of 1500w as I recall.
If I were to go through the effort, and I may one day do this, I'd just use an SMA Sunny Island {or 2 so I'd have 240v available} and probably a Leaf battery or two. I currently have a Sunny Boy 5000 on my larger array, so it'll work nicely with it.
