Nighttime is another situation in which the supplier does not deliver power, at least for solar.
Yes you need cords, appliances, and other equipment, including extra equipment if you are not connected to the grid, that is a given.
So without additional Equipment just having solar and a power wall wouldn’t help during outages.
