Abstract

See full text

The disclosed smart receptacle allows use of high voltage DC power, typically between 100 and 120 volts, for regular appliances such as computers and cell phone power adapters, coffee pots, heaters and some motorized devices. The receptacle prevents use of the DC power by AC appliances by monitoring for amount and or quality of inductance of a plugged in appliance. Other embodiments include local grid structures that provide locally resilient sources of energy, particularly solar electric energy, and methods for sharing power. One such embodiment provides a comprehensive apparatus that provides energy cost lowering and backup power by connection to utility power and to DC power such as from a DC grid or solar panels, while providing power to DC appliances.
