I am aware. Also no AI generated or derived answers please. It is against community guidlines.
The wide frequency is documented for use onky with troublesome generators. If you aren’t having trouble then you don’t need the feature.
By the way it is not deactivating the transfer switch when you disable wide frequency, it is just changing how the inverter reacts.
This is the main input relay and is the clicking sound you hear on generator connect. So there would be no transfer from in to put without it. The AI is incorrect.
