How to use it
Moves a house between the grid and an off-grid inverter (or a generator) without ever joining them. With an off-grid inverter as priority, the house runs on solar and battery and falls back to the grid when the inverter stops on low battery. A hybrid inverter already has this switch inside; an external ATS there is only for a generator or a manual bypass.
