What are you talking about? Of course, energy that isn't used in the household is pushed back to the grid.
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.
Without proper safeties in place back flowing power to the grid becomes extremely dangerous for line technicians
Do you know how these kits work? The whole point is that they're plug-and-play. 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.
The kits have built-in measures to avoid backfeeding, or they would be illegal. Where I live, they've been deemed so unsafe, failsafe or not, that you're just not allowed to use them.

These kits absolutely can push power into the grid, usually with payment for the generation. Just because they may not be allowed where you live doesn't mean they don't exist.
