Abstract: Power generating component connectivity testing methods and apparatus are disclosed. At a power generating component, a connectivity testing condition is detected. A connectivity testing procedure is performed on detection of the connectivity testing condition, to test connectivity in a system that includes the power generating component and an unpowered electrical system. Connectivity is tested before the electrical system is connected to a power grid. An indication of connectivity can be provided by receiving connectivity information indicating connectivity between power generating components and the unpowered electrical system; and providing a representation of the connectivity between the power generating testing procedure components and the electrical system. This representation could include, for example, one or more of: a connectivity alert, a visual representation of the power generating components; and a visual representation of the electrical system.
