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
Maybe just look at how these inverters work before babbling about. These kits all come with standard off the shelf micro inverters, or rarely bigger string inverters, and will feed back up to 0,8wk into the grid if the energy is not used in the household. If the connection to the grid is lost they turn off within less than 50ms, making them completely safe for line technicians
On loss of power these inverters cut off within 20 ms or so. These are grid-tied, not insular (though with hacked firmware some of the models can be made insular-capable).
