Classification: CPC H  G  Y | IPC G  H

Claim 6:
7. A method for monitoring a photovoltaic (PV) module, comprising:
receiving a sensed voltage signal at a voltage sense terminal of a measurement conditioning circuit from a string of PV sub-modules associated with the PV module;
receiving a voltage reference signal at a voltage reference terminal of the measurement conditioning circuit from the string of PV sub-modules;
generating digital measurement data at a digital measurement data output of the measurement conditioning circuit based on the sensed voltage signal in reference to the voltage reference signal;
generating a modulation clock signal at a modulation clock output of a transmitter circuit;
generating a measurement data stream at a measurement data stream output of a microcontroller circuit based on the digital measurement data at a digital measurement data input and the modulation clock signal at a modulation clock input;
generating an output communication signal at the transmitter circuit based on the modulation clock signal and the measurement data stream at a measurement data stream input;
generating a transmit select signal at a transmit select output of the microcontroller circuit based on the measurement data stream; and
transmitting the output communication signal from the transmitter circuit to a communication interface circuit.
