Abstract: Systems and methods for operating a power conversion system that includes a sole DC/DC converter are described. The systems and methods reduce a total number of DC/DC converters in a power system that includes an electric energy storage device and a photovoltaic array. The system and method provide for transferring electrical charge from the photovoltaic array and the electric energy storage device to an alternating current stationary electrical grid via a DC bus and an inverter.
