Since most homes are a grid tie system the solar shuts down when the power goes out. I wonder if home owners facing extended outages are finding ways around that?

Is there a way around it in an emergency?

I'd imagine in a solar powered house there is a provision to disconnect from the grid tie system and go totally independent if needed.

From what I have read I believe you are correct.

The benefit of grid tied sytem is that it's lot cheaper, the batteries on standalone sytem add a lot of expense but they also perform a crucial task beyond storage for night. Even during the day you can have wild fluctuations in power output, e.g. a bright and sunny day with those big white puffy clouds blocking the sun occasionally. The thing about electric is you either use it, store it or lose it.

A quick search says they have this type of inverter than can directly power things.

Looks like it has much lower wattage in power loss mode. You'd have to research it more but a lot of things you would want to power during a loss of power like a motor can be burnt up pretty quickly if there isn't enough power being delivered to them. If it has the means to monitor the draw and cut power if it can't supply it you should be good to go.

That said if you have an event like Irma a small gasoline generator used wisely could run for at least a week on 20 or 30 gallons of gas.
