Method, apparatus and system for crosstalk suppression of power line communication are provided. The method includes: receiving a joining request message; judging a matching state of the communication terminal based on a history matching record and communication terminal identifier, if matching state of the communication terminal is unmatched: sending a joining response message to the communication terminal; receiving an acknowledgment request message sent by the communication terminal after switch of the communication terminal is turned on; detecting voltage on power line between the communication terminal and an inverter corresponding to the power line communication transmitter, if voltage is within preset voltage range, sending an acknowledgment response message to the communication terminal; storing communication terminal identifier in history matching record and storing matching state of the communication terminal as successfully-matched. The method, apparatus and system can avoid malfunction of switch of the communication terminal during communication crosstalk.
