Actually it’s quite smart and simple l: you take any outlet in your house!
The ac/dc transformer those things simply feeds it’s energy into your house - after all a plug doesn’t care in which direction power flows. .those systems have an upper cap though to prevent people from overloading the net.
It’s really neat and simple! You basically lower your lower consumption by whatever these things produce.
I don’t know or have seen anyone using these small balcony cells with a battery though - while technically not a problem I think there’s simply not a use case: they don’t overproduce that much at any given time anyway.

It’s a regular German outlet, but they would be more comparable to a drier outlet here in the US, although without being rated for such high loads as an american clothes drier.
As another commenter said, They’re used to cover the base load of lights, fridge, small electronics. Most all of these systems won’t have any battery storage so the power either gets used in the moment by the home, or exported to the utility. That part isnt really any different from a typical solar installation in the US. They’re just smaller systems so it’s more accessible to lower income people and people that live in apartments.

US utilities often have anti islanding rules, so power is not allowed to be fed back into the utility without specific equipment designed to stop power flowing back when the grid is down.

The systems don’t output power until they sense a grid connection, and cut power immediately if the grid goes down.

Sounds like they are almost ready to go for most US requirements then. Some voltage tweeks and a plug change and we got something cooking.
