As nothing is fed through the Mains Switch box nothing could ever backfeed.
A heavy shed feed we had installed from the main fuse box is connected to a separate Fuse panel on the shed, that feeds the input to the ATS, the ATS can only switch it's output between Inverter AC input and that shed AC feed input, again, nothing can ever back feed.
The inverter would instantly trip or be destroyed if that could ever happen.
The ATS output feeds the Shed via a small breaker ELD box which splits the feed for: 1: Powering the shed and 2: A separate isolated emergency circuit running in the house, that circuit has no connections whatsoever to the main fuse box.
There is a separate existing Solar panel and "feed in" Inverter on the house, it's completely independent of the shed solar array, batteries and inverter.
I had an approved "Generator Input" change over switch fitted into the Main fuse box.
That won't be used unless we start having sustained power cuts, or they stop our
feed in tariff, in which case the Property will then be permanently disconnected from the stinking Mains supply.
