Power supply system
First Claim
1. A power supply system comprising a commercial electrical grid, a distributed power source, a storage cell, an appliance, and a controller configured to select a non-regular power transfer pathway among the power supply system components;
- whereinthe distributed power source, the storage cell, the appliance and the controller are located on a consumer unit side of the power supply system;
the non-regular pathway comprises a first excess power selling mode of causing excess power generated by the distributed power source to reversely flow into the commercial electrical grid, and a second assist mode wherein all power generated by the distributed power source flows into the commercial electrical grid, andthe storage cell supplies all power to the appliance in the second assist mode.

Abstract
A controller executes local generation and local consumption pathways of: supplying power from a solar cell to an appliance, and charging a storage cell with power that remains after subtracting power consumed by the appliance from the solar cell power. In the absence of excess power, the storage cell and solar cell supply power. Power supply from a commercial electrical grid covers a power shortage that remains after subtracting solar cell power and storage cell power from the power consumed by the appliance. The controller also executes a second excess power selling mode pathway wherein excess power flows into the commercial electrical grid, and an assist mode wherein all solar cell power flows into the commercial electrical grid, and storage cell power flows to the appliance.

11. A power supply system that supplies power to an appliance from power generated by a distributed power source, power stored in a storage cell and supplied power from a commercial electrical grid, the power supply system comprising:
a controller configured to select between a first pathway and a second pathway, wherein the distributed power source, the storage cell, the appliance and the controller are located on a consumer unit side of the power supply system; the controller is configured to select the first pathway by performing operations comprising;
supplying distributed power source power to the appliance;
charging the storage cell with power that remains after subtracting power consumed by the appliance from the power generated by the distributed power source;
when there is no excess power, supplying the appliance with power stored in the storage cell together with the power generated by the distributed power source; and
supplying the power from the commercial electrical grid to cover a power shortage that remains after subtracting the power generated by the distributed power source and the power supplied by the storage cell from the power consumed by the appliance;the controller is configured to select the second pathway by performing operations in which; a first excess power selling mode causes the excess power to reversely flow into the commercial electrical grid, and a second assist mode causes all power generated by the distributed power source to flow into the commercial electrical grid, and the storage cell supplies all power to the appliance. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
