I mean…if there is no grid frequency detected it automatically breaks connection between the house and the grid and keeps supplying the house from the panels and batteries. When it detects grid frequency again it reconnects the house to grid. It’s a fairly simple concept.
They detect incoming frequency, not voltage. And yes, they absolutely detect the difference, I have one, it works exactly like this.
How do you detect the frequency of voltage that doesn’t exist? Hold a wire up in the air and measure the frequency and let me know what you find.

Okay now try again but there is no grid.
If there’s no grid, there’s no connection to the grid to break. So that non-connecton will remain in the broken state.
Hey moron. How do you suppose the inverter knows that?
By checking. How the fuck else would it know.
It doesn’t know, moron. That’s the point.
