If a solar sales guy says it doesnt power your house they are confused. It uses the grid as a battery. Whatever power the panels cannot make it takes from the grid. Whatever surplus the panels make goes back to the grid, running your meter in reverse. The inverter phase matches to the grids AC frequency.

A grid tied system shuts down when the grid fails. A hybrid can be set up to take over.
