A dilemma I need cleared up

[NeatFreak84]

As someone that's in the process of installing a solar system i'm diving into rules and compliances quite hard and i ended up with a dilemma i hope someone can clear up. An inverter tied to a grid, let's say a 4kw one is there to give me power in a separate outled if the power goes down which is clear enough. The problem i'm having is with the nec 690.12 rule which says that i need to have rapid shutdown in the interest of first responders which is get. My dilemma is how to combine the backup option with the shutdown one working at the same time? Afterall the point is to have power in case the power is down but i cant if i need to have a rapid shutdown which kills the power if the grid is down. It's confusing and i hope someone can make some sense out of this

im thinking that maybe u can use a small backup battery? for the signal generator to keep the shut down working while on an outage
