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)

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