US Patent 10139846 DC power grid and equipment

Direct current electric grids are provided that allow independent power generation and consumption at the neighborhood level. In an embodiment power is uploaded and downloaded to each node via monitoring of node voltage and setting high vs low priority loads to optimize for maximum power usage. Embodiments allow a new paradigm wherein electrical supply is set by total available installed power generation and wherein all available power is used, via prioritization. New apparatuses and circuits are provided that provide higher efficiency by utilizing solar power generated at low light conditions and by minimizing the number of power alteration steps between power generator and power consuming device.
