Not a strawman (I don't think? not sure what you meant by this..), just very curious. You have a setup that is in between useless when grid is down, and fully self-sufficient. Seems possibly very practical to me, but I haven't heard of it before.

It is a very uncommon setup, I've met installers that don't know about it. The new generation of microinverters enable this setup more easily, so it should become more common.
