It appears that 365 is using the Hytec Continuous Power System [], which is a motor, generator, flywheel, clutch, and Diesel engine all on the same shaft. They don't use batteries.

If the flywheels spent their energy before the generators came online, they don't have the ability to start the generators up without utility power (unless they purchased the Dark Start option, which is simply extra batteries).
