  "textContent": "A PV module, which includes PV+ and PV− output ports. An output capacitor Cout is connected to PV+ or PV− port through an electric switch. One end of a power inductor L is connected to OUT−, and the other end is grounded. The power inductor L is connected with a resonant capacitor C and an impedance resistor R in parallel. One end of a blocking capacitor C is used as the PLC+ port, one end of a blocking capacitor C is used as the PLC− port, and signal sources are connected to OUT+ and OUT− in parallel and send “Keep Alive” signals based on SunSpec communication protocol. PLC+ port and PLC− port are connected to a signal coupling input port of a control IC, and the control IC controls the electric switch. When the signal is decoded and extracted, the electric switch will remain on, otherwise it will be off.",
