The key seems to be that the on-board generator is designed only to provide enough power for cruise. Take-off and climb will have this generator's power supplemented by LiIon batteries. This means that because the generator will always operate at full capacity, it can be much more weight-efficient than one that is required to handle the peak loads associated with take-off and climb.
