Yes the video did explain the reasons ext, but is there nothing i can stick to my consumer unit or outside unit to stop export? How do backup generators work then?
You would need to install something like a “break then make” switch that isolates the house from the main line before feeding power back from your local source(s)
Unplug from the wall and you’re good to go. Otherwise you’re back feeding and could injure a worker.

For a whole home system there needs to be an auto shutoff. It isolates the house.
