Just occurred! Most modern generators use a DC output from the engine and feed that to an inverter.
The old style genny HAD to run at a fixed speed to get the proper 50/60Hz (but I bet they slipped a LOT under load?) A DC-AC inverter setup allows the engine to idle at low loads and speed up as necessary for high ones.
Does not seem rocket science to insert a big battery into that scenario?
This is a whole area of electrical engineering that I know practically FA about!
