Title: BACKFEED POWER SUPPLY FOR SOLAR POWER SYSTEM
Abstract:
A solar collection system may collect energy from the sun to generate electricity for distribution on an electrical grid. In addition to generating electricity, a solar collection system may include support devices such as motors, controllers, sensors, and other support devices to perform various tasks to allow the solar collection system to more effectively generate electricity. When the solar collection system is generating sufficient power, the support devices may be powered by the solar collection system. However, when the solar collection system is not generating sufficient power, the support devices may be powered by a backfeed power supply circuit coupled to the electrical grid.
