Abstract
A method for direct current power line communication in a photovoltaic system includes (a) transferring power between at least one photovoltaic device and a load using a power line, (b) maintaining a magnitude of a current flowing through the power line above a threshold value in a normal operating mode of the photovoltaic system, (c) detecting a change in operation of the power line in response to magnitude of a direct current component of the current flowing through the power line falling below the threshold value, and (d) in response to the detected change in operation of the power line, decoding operating state of the power line to obtain information.
