It does when the grid is running on batteries for extended periods of time. I guess it just comes down to what is cheaper between x% more batteries and y% larger conductors.

If the solar is remote and the batteries are near the load though you don’t need any more batteries in this situation, just more panels.
Colocating batteries with panels should be more cost effective as they can avoid the DC-AC-DC conversion while using half as many inverters as 2 separate installations.
That doesn't sound free.
