Does a Grid Tied System work at night or during low sunlight hours?

Grid Tie Systems use generated power from the Sun throughout the Day and sell back excess power generated. At night, power is purchased from the Utility Company. Your home will have continuous power from both sources as long as the system senses power from the Utility Grid. If the grid loses power the system will shut down so it doesn’t send power back into de-energized utility lines. This is a safety requirement for all grid-tie systems.
