Unplug from the wall and you’re good to go. Otherwise you’re back feeding and could injure a worker.
Comment on Britain’s biggest community solar farm forced to shut over grid overload fears

last night i watched a video about plug in solar and it appears that the rules say that when you lose mains power (power cut), your system must also terminate and shut down. I didn’t realise this was the case, and thought i could get a small battery to power my home in a power cut (╯°□°）╯︵ ┻━┻

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.

That’s a safety feature so a breaker actually cuts the power supply to your home/room/whatever when it’s turned off.

I have generator that automatically kicks on when my power goes out. It shuts down the grid connection before it does so to avoid feeding power back to the grid. You just need something similar that would cut off the grid when the power goes out and switch to your battery.
