MicroInverters and WH Battery Backup - Ac / Ac Coupling/ Is this possible?

Good evening! I have tried to dive deep into research prior to making the move to our new home. The home has 46 SEG 440W panels across the roof lines. All are managed via Enphase IQ8 micro inverters that come down to an Enphase Gateway.

I would really like to maintain the system in its current state as its perfect for 110% of what I expect our usage to be in Central Florida.

How can I take the output from the enphase microinverters and put that into a panel that can accept back up batteries. Whether that be the ECO Flow Smart Panel 3, EF Smart Gateway, EG4 (grid/ flex BOSS). All of my research had me leaning towards series tied panels with high voltage and low amperage into a free standing wall mount inverter. This seems like the MOST capable and adapatable system however, this is the scenario I am in.

TL;DR- Quantity 46 - 440W panels with IQ8 micro inverters. How to add (off the shelf) whole home back up battery.
