Abstract

An apparatus and method for determining and providing a controlled power from a first apparatus to another apparatus is disclosed. The apparatus includes an energy source configured to generate a power output, a power converter electrically connected to the energy source to receive the power output and to output a conditioned power, and a transfer switch configured to selectively couple the conditioned power to an external apparatus. The apparatus also includes a controller in communication with the external apparatus and configured to receive apparatus parameter data related to the external apparatus, determine a power requirement of the external apparatus based on the apparatus parameter data, operate the power convertor to output conditioned power that meets the power requirement of the external apparatus, and control the transfer switch to couple the conditioned power that meets the power requirement to the external apparatus.
