The PV industry has pioneered the development of islanding detection and prevention measures. To satisfy the concerns of electric power providers, commercially-available utilityinterconnected PV inverters have implemented a variety of islanding detection and prevention (also called anti-islanding) techniques. The industry has also developed a test procedure to demonstrate the efficacy of these anti-islanding techniques; that procedure is the subject of this document. This standard provides a consensus test procedure to evaluate the efficacy of islanding prevention measures used by the power conditioner of utility-interconnected PV systems. Note that while this document specifically addresses inverters for photovoltaic systems, with some modifications the setup and procedure may also be used to evaluate inverters used with other generation sources or to evaluate separate anti-islanding devices intended for use in conjunction with PV inverters or other generation sources acting as or supplementing the antiislanding feature of those sources. Inverters and other devices meeting the requirements of this document can be considered non-islanding, meaning that under reasonable conditions, the device will detect island conditions and cease to energize the public electric power grid
