Tigo Rapid Shut Down with SMA

Hi All,
I need to meet the new NEC 2019 code for rapid shut down.
I was wanting to use the Tigo modules for RS, Safety, monitoring and optimization. I am not sure if this will work with a hybrid grid-tied-battery backup system? I know the Tigo RS senses the grid and shuts off the PV panels but what about a hybrid system? If the grid goes down will the Tigo allow the SMA battery backup continue to use the panels or will the panels be cut off when the grid goes down?

That is a feature inside the SMA devices.
You have to ask to the SMA support what happen on those two devices (sunny boy and sunny island) if the grid is down."
