This is common sense, that way emergency services can easily isolate your power without having access to your inverter or solar isolation switches if they are inside your house and inaccessible.

Nice and neat installation by the way!

This also is important when there is a fault in your suburban power grid. If the solar was still being feed into the grid during a black out. The linesman working on the line would get zapped, due to the solar making the lines live.
