What do you mean by "inverter power sources"? A new build cost optimal power grid would get 90-98% of its power from solar, wind & batteries per Ember Energy.

solar is an inverter power source

electricity from a DC to AC inverter instead of a direct an generator powered by steam

yeah a grid that was more than 30% inverter sources (which includes batteries) would likely fail randomly. the big spinning metal in the stream generators provides literal inertia to the grid, flywheels can replace that but those also cost money.

solar panels are cheap... of you want 200-400v DC, but if you want a national scale grid with 99.9999% uptime... they're actually not
