The grid-tied microinverter cannot do this on its own. It is incapable.
A person can add other things to the scenario and the microinverter may elect to play ball, but it is simply incapable of kickstarting bloody anything on its own.
Are there any other wildly imaginative corner cases you'd like to explore that have nothing at all to do with balcony solar, as it is implemented in Germany?
I was rebutting your incorrect assertion in https://news.ycombinator.com/item?id=45487471 about what hypothetical microinverters were or were not "utterly incapable" of. The comment you have just posted is irrelevant to that.
The design features of currently existing microinverters are irrelevant to hedora's point about what microinverters could be designed to do, except insofar as they constitute an existence proof. (Obviously something is possible if it's already being done, but the inverse is not true.)
