What is Anti-Islanding?
Here’s Why Anti-Islanding is important:
Electric utility companies refer to residential grid-tie solar power arrays as distributed generation (DG) generators. They use this term because your solar panels are producing and distributing electrical power back into our utility grid.
One common misconception is that a grid tied system will continue to generate power during a blackout. Unless there is a battery back-up system, the gridtie solar system will not produce power when the grid is down.
