One critical safety feature in grid-tied photovoltaic (PV) systems is anti-islanding. 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. You will see why this matters, how inverters do it, and what codes require. Anti-islanding protection devices are the essential safeguard designed to counter this very risk.
