No, that’s not how it works in the general case. There are ways to setup a house to back power but it’s more complicated than just plugging it in.

So what you’re saying is that the general case is that it feeds back into the grid unless there are additional measures taken? But at the same time, it’s not the general case? Huh?

Without proper safeties in place back flowing power to the grid becomes extremely dangerous for line technicians

Which is why, where I live, you have to register your devices with the utility company.

Do you know how these kits work?

Yes I do. Had one for some time before we got our own house and ramped it up to a “real” 8 kWp array.

If the feed back into the grid, they are not plug and play and will require coordination with your power company lest you accidentally kill someone because you’re backfeeding into a line they turned off so they could work on it.

Which is exactly why there are harsh regulations about the index of these things in Germany. Before you plug it in, you have to register exactly where you’re plugging what in.

These units do not push electricity into the grid unless their fail-saves are bypassed deliberately or fail catastrophically.

What are you talking about? Of course, energy that isn’t used in the household is pushed back to the grid.

Not at home and can’t try it, but for other racing games it’s enabled by default (Redout e.g.), so it shouldn’t really be much of an issue to turn it on.
