Anti-islanding function: when there are high-voltage, low-voltage, high-frequency, or low-frequency faults in the power grid, the relay at the grid port of Deye inverter will automatically disconnect in time. When the power supply is restored and the voltage and frequency reach the permissible values, the relay at the grid port will be closed automatically.

Photovoltaic (PV) systems are increasingly assuming a significant share in the power generation capacity in many countries, and their massive integration with existing power grids has resulted in critical concerns for the distribution system operators. Most of these critical concerns arise due to abnormalities at the grid side (undervoltage and short-circuit events), …
Islanding produces a dangerous situation for electric personnel who might not realize a particular circuit is still energized. Without anti-islanding, the "should-be-dead" power lines are being back-fed by the generation from the island. Without inverter anti-islanding protection, equipment failure can occur. How Does Anti-Islanding Work?
An important technical concern to microgrid operation is unintentional islanding events. Several methods for islanding detection are proposed in the literature (Li et al. 2014), but most of them may fail when multiple inverters are in parallel or when they may generate important power quality degradation which gets worse with increasing DG penetration (Reddy and Reddy 2019; Mlakić …
Islanding phenomenon is undesirable because it leads to a safety hazard to utility service personnel and may cause damage to power generation and power supply facilities as a result of unsynchronized re-closure.
