Method and system for communication between inverter and solar module

Abstract:

Technologies for communication between an inverter and a solar module are disclosed. The disclosed technologies include monitoring a voltage and/or current of the solar module to determine a corresponding voltage waveform and/or current waveform and determining whether the voltage waveform and/or current waveform includes an encoded message. If a message is encoded in the voltage waveform and/or current waveform, the solar module may perform one or more actions. For example, the solar module may adjust an operating voltage, current, or power, adjust a switching frequency or duty cycle of one or more converters of the solar module, initiate a global maximum power point search, and/or other actions.
