When the grid goes down you have battery backup and when the grid is up you sell your excess production back to the grid.

This way your batteries last much longer and you still get a benefit from your system.
Good quality batteries are rated to last thousands of complete cycles nowadays, even more for partial cycles. If you don't use them, they'll eventually die of old age.

Selling to the grid is not a good option in some places.
