Do inverters have anti-islanding protection?

If you hear someone say that their inverter is fitted with anti-islanding protection, it simply means that it has islanding detection (often based on voltage and frequency detection) and can sense when the grid is down. That way, it can stop feeding power back to the grid and protect the utility workers.

How to Achieve Anti-Islanding in Inverters with Energy Storage

However, with anti-islanding protection, the inverter ensures that when grid power is lost or excess power is produced, the energy is directed towards local loads or stored in energy storage systems, instead of being sent back to the grid. This helps maintain system safety and prevent damage to grid infrastructure.
