Abstract
An apparatus is disclosed where a Maximum power point tracking (MPPT) circuit is used to transmit data into the photovoltaic network, where the PLC communication is pulling the required transmit energy from the photovoltaic network, where the transmit chain is using the MPPT transistor of the photovoltaic DC Optimizer, where the transmit chain is transmitting data using Standard modulation such as ASK, FSK, S-FSK, BPSK, OFDM, etc. . . . where the transmitted data are passed on to the powerline network by the use of an “Input signal” adaptation stage, where signals summation is performed to create a command signal used to control the transmission of data by providing enough voltage to polarize the Transistor (i.e: MOS FET) used in the powerline path.
