AC & DC Coupling Simultaniously

[Positive Power]

Just a quick question that I'm sure I already know the answer to but would love a little confirmation.
One of my recent installations is a DC Coupled (FM100 AFCI) Dual Radian Grid Connected (Net Metering), system with 750Ah of SimpliPhi batteries. The System is working great and the client is happy. So happy in fact she wants to add more solar. Instead of using another FM100, I'd like to AC Couple the new solar array (using Enphase IQ7+) to the Radian's critical load panel. I have installed multiple AC Coupled systems, but just not one on my existing DC Coupled Systems. I see no reason why both cannot work harmoniously, assuming I stay below the 75% of the 16kW output of the dual radians (no more than 12.8kW of Grid Tied input) and the batteries can comfortably handle the added charge current (which they easily can). Does anyone else see any issues with this combining the two different strategies?

The Radian has AC-coupling capability. There's no reason this won't work. My system does this with Skybox but the Radian is similarly capable. I'm sure there are others on the forum who are already doing this with their Radian(s).

That’s my thought too. Indeed I have seen others do it as well. Thanks for your feedback.
