Claim 19:
20. A method for controlling an uninterruptible power supply system having a first input configured to be coupled to a main-power source, a second input configured to be coupled to a backup-power source, an output configured to be coupled to at least one load, a first group of one or more power modules coupled to the first input, the second input, and the output, and a second group of one or more power modules coupled to the first input and the second input, the method comprising:
receive, from a grid controller coupled to the main-power source, a request for power;
control, responsive to receiving the request for power, the uninterruptible power supply system to operate in a reverse mode of operation;
controlling, in the reverse mode of operation, the first group of one or more power modules to provide power derived from the second input to the output, wherein a majority of the power provided by each of the power modules of the first group of one or more power modules in the reverse mode of operation is provided to the output; and
controlling, in the reverse mode of operation, the second group of one or more power modules to provide power derived from the second input to the first input, wherein a majority of the power provided by each of the power modules of the second group of one or more power modules in the reverse mode of operation is provided to the first input.
