It requires a foolproof method of ensuring that the generator cannot be connected to the outside supply.
QuoteIt requires a foolproof method of ensuring that the generator cannot be connected to the outside supply. This is not necessary true, not even from day one we use electronic. we got AC from AC power grid, in the grid there are a lot of power plants/generators interconnect each other, all is need is sync. The tech behind is power grid feed-in.for people installed solar panel, solar power grid feed-in is very popular and profitable since utility corp pay for feed back power. The device is Grid-tie inverter.
This is not necessary true
If you connect your own AC power supply to the mains WITHOUT PERMISSION AND APPROVAL FROM YOUR ELECTRICITY SUPPLIER
Connecting it via a grid feed-in unit of the sort you show is also NOT SAFE unless your electrical supplier has explicitly authorised that
The most reliable way to ensure that IMO is to have a mechanical switchover system wired so that it is physically impossible for the two sources to be connected together.
