Solar inverter island control

This page explains how safe islanding works, what to specify, and how to size a solar panel microgrid for real outages. If the grid goes down, they must stop producing within fractions of a second. . Anti-islanding protection is a commonly required safety feature which disables PV inverters when the grid enters an islanded condition. This might sound like a good thing, as your home still has power from your solar panels while everyone else has no power. When a solar system continues to send power into the grid despite a disconnection or failure, it creates an “island” — a scenario that can be. . This mechanism prevents solar inverters from continuing to supply power to the grid during a power outage, thereby protecting utility workers and maintaining grid stability. [PDF Version]
