Not just fixed but most engineers design with UL standards so while they advertise maximum output they're all most efficient somewhere around 80% their maximum.
The batteries help the grid because they can maintain a minimum demand the power plants need and compensate for any excess demand that would tax the grid infrastructure.
I've never tested a generator, are they all producing pure sine waves?
