SYSTEMS AND METHODS FOR OPERATING WITH SECONDARY POWER SOURCES

Aspects of the disclosure include a power supply system comprising at least one first input configured to be coupled to a primary power source, at least one second input configured to be coupled to a first and second secondary power source, an output, a first and second power supply coupled to the first and second inputs, and at least one controller configured to receive a load-power measurement associated with a required load power, determine whether the required load power is greater than secondary power available from the first secondary power source, and control, responsive to determining that the required load power is greater than the available secondary power, the first power supply to provide power derived from the primary and secondary power sources to the output, and the second power supply and second secondary power source to operate in a standby mode to prepare to provide power to the output.
