Abstract: A Smart Energy Management System (SEMS) configured to manage electrical power from diverse power sources and supply electrical power to one or more output buses. Some embodiments feature a generally transportable SEMS where the power sources include power storage devices such as batteries, capacitors, or other devices engineered to store electrical energy and alternatively, power generation or conversion devices such as photovoltaic modules, AC-DC inverters, charging devices, DC dynamos, AC or DC electric generators, and regenerative braking devices.
