Abstract
Devices and methods for electrically decoupling a solar module from a solar system are described. In one embodiment, a solar system includes a string of a plurality of solar modules coupled with an inverter through a DC power line. An AC input is coupled with the DC power line. A device is also included and is configured to provide a closed circuit for one of the plurality of solar modules if an AC signal voltage from the AC input is present on the DC power line, and is configured to provide an open circuit for the one of the plurality of solar modules if no AC signal voltage from the AC input is present on the DC power line.
