So what micros are you using to AC couple. I have never gotten AC coupled to work with my IQ8s. Maybe part AC and part DC works better? What DV / AC ratio do you have?One exception to its good behavior: On two occasions in the last couple weeks the system got stuck in some kind of cycle sending power from the battery to somewhere unknown. I suspect it was going to AC-coupled microinverters that were periodically checking grid impedance by drawing a load (like they do during initial startup). I'll eventually figure it out, but don't have time to mess with it at the moment.
