    摘要: Systems, devices, and methods for energy systems that include one or more modules are configured to connect to a power grid. Each module outputs a respective voltage waveform and/or a current waveform to a load. A controller is configured to periodically cause at least a portion of the one or more modules to output an increased voltage and/or current level at a specified harmonic frequency. An islanding detector is configured to detect, based on an impedance of the grid, when the one or more modules are in an island condition.
