Abstract
A power supply system is disclosed. The system comprises an AC power source from a power grid and a DC power source from an alternative energy source. The alternative energy source is a solar system in the preferred embodiment. The system provides a means of supplying the electrical appliance the DC power from the solar system with the higher priority. According to one embodiment of the present invention, a switch controlled by a controller provides a means of switching the power supply in between the two power sources without disrupting the operation of the appliance. According to another embodiment, a voltage regulator combines power generated from both sources to supply the power for the appliance with consuming the DC power from the solar system as the priority source.
Claims20
A power supply system for an electrical appliance comprising:
- (a) a first means of power supply providing an AC power from a power grid;
- (b) a second means of power supply providing a DC power generated by an alternative power generation system;
- (c) a switch providing a means of switching in between said first and said second means of power supply;
- and
- (d) a controller providing a means of optimizing power consumption by supplying DC power from the alternative power generation system as the first priority and by supplying AC power from the power grid as the second priority.
A method of supplying power to an electrical appliance through a power supplying system including an AC power source and a DC power source by an alternative energy generation system, the method comprising:
- (a) measuring by a measurement unit of a controller the DC power generated from the alternative energy generation system;
- (b) supplying the generated DC power to the appliance if the measured DC power is in exceeding of a threshold value;
- and
- (c) supplying the AC power to the appliance if the measured DC power is below a threshold value.
An electrical connecting system for connecting an electrical appliance to a power source including an AC power source from a power grid and a DC power source generated form an alternative energy generation system, the connector comprising:
- (a) a first means of connecting the appliance to the AC power source;
- (b) a second means of connecting the appliance to the DC power source;
- and
- (c) a switch for switching in between two said means controlled by a controller.
