It disconnects the solar system from the grid. If you have batteries I think the batteries can still provide power for your home. I do know they system I have needs to see 220 volts from the grid to stay connected. If the grid goes down, it disconnects. It's a safety feature for the line workers. They can drop the power from a transformer, but if the solar system is still connected, the lines they are working on are still hot.
There is also a manual disconnect that the fire department uses. When they respond to a fire they pull the main meter. In the past the solar system kept working and had to be disconnected manually. With the current system, if the meter is pulled, the solar system automatically disconnects. It may still charge batteries, I don't know, but there is no power to the house.
