99% of systems are grid tie, so unless you’re spending another $7k for an ATS and associated infrastructure or you’re 100% off grid, your power still goes off.

And I should clarify that you technically can get away with a less expensive interlock system, but you're still paying a few thousand dollars to have your panel replaced (unless you feel comfortable doing that sort of electrical work yourself).
Making a system non-grid-tie is comparatively expensive, that's why grid tie is so common. People think you add solar + batteries and you're ready for doomsday - not quite.
