A software abstraction layer for energy generation and/or storage systems. In one embodiment, a method is provided that can comprise receiving, by a site gateway, one or more standardized operating parameters for a physical component of an energy storage system, and translating, by the site gateway, the one or more standardized operating parameters into one or more vendor specific parameters, where the one or more vendor specific parameters are specific to a vendor-defined communication protocol supported by the physical component. The physical component can then be controlled using the one or more vendor specific parameters.
