Converting grid-tied inverter for off-grid use

[briti1]

I have a grid-tied Outback GVFX 3524 LA paired with a Outback FLEXmax 80 charge controller, Mate 2 and a hub 10 that I would like to use for an off grid system. Is this possible? If so are there any modifications that need to made to the GVFX to set it up for off grid use?

According to "this" specification, that model can run off grid. It says it can provide power when the grid is down. I've never used one but it appears there is nothing to do but disconnect it from the electrical system. As long as your charge controller can keep up with your load while charging the battery, you're good.

"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."
