Anti-Islanding Testing
Islanding occurs when a local energy generator continues to feed power into the grid during a grid outage, creating a hazardous "island" of energized equipment.
Pacific Power Source has released a white paper about the fundamentals of Anti-Islanding testing. Read more to find out what solutions we have to offer.
What is Anti-Islading?
- Occurs when DER power grid during outage
- Protection ensures safe disconnect
- Prevents injury and equipment damage
- Ensures compliance (UL 1741 SA, IEEE 1547.1, IEC 62116)
- Maintains grid stability
Required for PV inverters, V2G chargers, BESS, microgrids
Key Applications
Anti-islanding testing is mandatory for DERs that export power to the grid such as:
- Solar PV Inverters
- Bidirectional EV Charges
- Energy Storage Systems (ESS)
- Vehicle-to-Grid (V2G) / Vehicle-to-Everything (V2X) Systems
- Microgrids and Smart Inverters
Pacific Power Source’s AZX and GSZ Series grid simulatorsdeliver a smart, application-focused approach to anti-islandingtesting.
With built-in automation, grid emulation, and compliance support, we empower test engineers to move faster, test deeper, and ensure that grid-connected systems meet the strict safety and reliability standards of today’s evolving energy landscape.
