A multi-level inverter control system includes a power storage system having a high voltage terminal, a low voltage terminal, and an intermediate voltage terminal. The intermediate voltage terminal is at a voltage between the high voltage terminal and the low voltage terminal. A multi-level inverter includes a plurality of switches, a high voltage input connected to the high voltage terminal, a low voltage input connected to the low voltage terminal, and an intermediate voltage input connected to the intermediate voltage terminal. A controller is controllably coupled to the multi-level inverter. The controller includes at least a processor and a memory. The memory stores instructions configured to cause the controller to operate the multi-level inverter in a three-level inverter mode, a full power two-level inverter mode, a first partial power two-level inverter mode and a second partial power two-level inverter mode.
