Grid-tied inverters only push power if it senses the grid. It’s a standard feature and has been around for years. Off grid inverters push no matter what. The situation you fear is somebody not knowing what kind they have and just plugging it in.

Thanks. I didn't know these existed and worked out of the box. Now I'm very curious to know _how_ they work.
