Systems and Methods for Using a Power Converter for Transmission of Data over the Power Feed
First Claim
1. An apparatus, comprising:
- a photovoltaic energy production unit to generate electricity;
a local management unit, coupled between the photovoltaic energy production unit and a connection of energy production units forming a string bus, the local management unit having a controller and switching circuitry, the controller to provide a control for the switching circuitry to deliver electrical energy to the string bus; and
a communication transmission modulator, coupled to the local management unit, to modulate the control with data to be transmitted from the local management unit over the string bus.

Abstract
Apparatuses and methods include a photovoltaic energy production unit to generate electricity. A local management unit is coupled between the photovoltaic energy production unit and a connection of energy production units forming a string bus. The local management unit includes a controller and switching circuitry. The controller provide a control for the switching circuitry to deliver electrical energy to the string bus. A communication transmission modulator is associated with the local management unit. The communication transmission modulator modulates the control with data to be transmitted from the local management unit over the string bus.
