I'd be worried about the inverters in large commercial solar plants. On a sunny day you could easily cause a blackout by turning enough solar capacity off at once. Maybe shut down the entire grid when the sudden power imbalances trip the self- protection in half the grid. That's a pain to recover from. Spain went through that not too long ago

But maybe rapidly switching residential solar on and off in a coordinated way can also do funny things to grid equipment
