Method and system for emergency operation for a modular multilevel converter including a central controller and a plurality of battery modules. The respective battery module is given a respective switching state by the central controller at each switching stroke, through which a respective energy accumulator is connected to a respective energy accumulator of a respectively adjacent battery module. Through a module monitoring, a respectively faulty energy accumulator is reported to the central controller. For the respective battery module with a faulty energy accumulator, a bypass switching state is determined at each further switching stroke. If a threshold value defined by a specified number of faulty energy accumulators tolerable for an operation of the modular multilevel converter is exceeded, an emergency operation is caused, which includes an operating state change from “operation mode” to a “repair mode”; display of the same; and restriction of a further operating time until repair.
