H-bridge inverter as part of the communication channel for deploying power line communications over solar photovoltaic energy system

Power Line Communication (PLC) is a communication method where the existing Power Line carries data. The home automation associates the usual electrical cabling to the renewable plants for smart home, smart grid. The use of PLC technology permits the use of the existing electrical network for data transfer. The use of renewable energy helps to reduce the electrical energy consumption. The user can also sell back energy to the utility during his off time, daylight. The different components of a low voltage low wattage solar photovoltaic system are monitored by the end user. The characterization of the inverter as medium of communication permits the deployment of PLC technology over the solar photovoltaic energy system. Combined BFSK modulation and Manchester coding were implemented. At 120 bps, data were transferred over a 230 W modified sine wave inverter, simplex from the DC bus.
