- bombcar 3y agoThere’s a lot of intelligence in a transfer switch that allows island mode - because it has to generate a sine wave when no utility one is present and sync back up with it when one returns. The cheapest ones just cut power when the sine is lost and then make their own, and cut power when they see it return and then sync.
- Scoundreller 3y agoThe much cheaper and covers many/most use cases alternative would be a unit that disconnects anything on-grid, and has some in-unit/on-unit sockets you can use during grid-fail at point of device or run extension cords to.
