What are the options for a grid-tied array to continue???

I know that normally in a grid-tied system, it is not possible to receive power from the array when the utility is not operating. However, I know that some inverters come with AC switches that allow for this option. For instance, the OutBack GTFX2524 2.5kW 24V Grid-Tie Inverter data sheet states that “Our built in transfer switch automatically disconnects your loads from the utility grid and powers them from the inverter in the event of an outage, allowing you to continue using your solar and battery back-up power, unlike traditional grid-tie systems.”

Many of Outbacks Inverter models allow for Grid tied, Off Grid, and modes that offer a combination of the two which includes a battery backup that keeps the system up and running should the grid go down. You can see the different modes on the FXR series here:
