Abstract: A photovoltaic module monitoring apparatus includes a driver module, configured to: receive a status request differential signal sent by an inverter of the power system; obtain, according to the status request differential signal, status information of a photovoltaic PV module corresponding to the photovoltaic module monitoring apparatus; modulate the status information of the photovoltaic PV module to generate a status response differential signal; and send the status response differential signal to the inverter; and a bypass module parallelly connected to the driver module, configured to transmit the status request differential signal and the status response differential signal, where an impedance of the bypass module is less than an impedance of the photovoltaic PV module.
