Your islanding solar inverter works independently from the power grid. If there's a storm or other event that knocks out the main power grid, your solar power system will continue running and providing power to your home. We mention this because many people mistake going solar with going off-grid, but that's typically not the case.
Islanding refers to a potentially dangerous mode of operation of a grid-connected PV inverter where it continues to operate even when the utility grid has been switched off or the distribution lines have been damaged, preventing the delivery of electric energy to the load.
Grid-connected PV inverters are electronic devices that convert DC power from photovoltaic (PV) solar panels into AC power that can be fed into the utility grid. They are required to have passive anti-islanding protection methods. These methods cause the PV inverter to stop supplying power to the utility grid if the voltage amplitude or the frequency of the point of common coupling (PCC) between the local customer load and the utility grid strays outside of prescribed limits.
Solar islanding is when a home solar power system continues to generate electricity even though the grid is down. Many people would consider this a good thing, as your home still has power from your solar panels while everyone else has no power.
However, your home can be a solar energy island with renewable energy available during a power outage or blackout. Integrating a solar inverter with island mode and battery storage will give you this capability while maintaining a connection to the grid.
To detect and prevent solar islanding, various anti-islanding measures are employed, such as using an inverter with PV system s that can detect changes in phase. These measures include using specialized inverters that can monitor changes in grid voltage and frequency in solar power systems.
