Power line communication device, power line communication system, power line communication method, and power line communication program

摘要

Provided is a power line communication device capable of performing reliable power line communication, without requiring detection of switching noises. The power line communication device corresponds to an MPPT controller (20S) for performing a communication through a power line (PL), and includes a communication unit (25) that communicates data through the power line (PL), a switch unit (23S) that controls supply-power supplied from a PV panel (10) through the power line (PL), and an MPU (26) that performs on/off control of the switch unit (23S) while avoiding a timing at which data is received by the communication unit (2).
