Inertia.  Not magic but physics.   A store of energy that can be drawn
on instantly for several seconds.  Only an inverter with a massive
energy storage system could match that; domestic systems can't.

 A boiler full of superheated water stores a lot of energy too. And
hydraulic steam valve actuators move fast.

Not all that fast. 50Hz is probably more than they could track. 60Hz would be even more difficult.
