Distributed power manager
A distributed power network includes a power bus infrastructure distributed over a region with node points provided to interface with controllable power nodes. Each power node can be connected to an external power device such as a DC power source, a DC power load, or a rechargeable DC battery. The power nodes form a communication network and cooperate with each other to receive input power from DC power sources and or rechargeable DC batteries connected to the power bus infrastructure and distribute the power received therefrom to the power bus infrastructure for distribution to the DC power loads and to rechargeable DC batteries.
