How It Works
Direct Current electricity is passed to an inverter which is grid tied. The inverter monitors the alternating current mains supply waveforms and generates electricity that is phase matched. The DC electrical system is attached to the mains via this mechanism.
Because the local system is phase matched, electricity can be drawn from the mains in the situation of a generating shortfall or discharge in batteries.

Famous quotes containing the word works:
“I shall not bring an automobile with me. These inventions infest France almost as much as Bloomer cycling costumes, but they make a horrid racket, and are particularly objectionable. So are the Bloomers. Nothing more abominable has ever been invented. Perhaps the automobile tricycles may succeed better, but I abjure all these works of the devil.”
—Henry Brooks Adams (1838–1918)
