  • Publication number: 20130043723
    Abstract: An electrical power supply arrangement includes a solar power device that converts sunlight into DC electrical power. A DC load runs on the DC current electrical power. The DC load may be controlled or adjusted to consume a maximum amount of the electrical output of the solar power device. A DC-to-AC converter converts the DC electrical power into AC electrical power. A controller enables the DC-to-AC converter to receive a portion of the DC current electrical power from the solar power device only if all of the DC current electrical power cannot be consumed by the DC load.
