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.
Is this part of german systems, or is it simplified?
That plus changes to laws in most states. Utah is the only place that allows this type of grid tied solar without permits, new meter, etc. Hopefully more states will follow soon

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.
