3-1-1 Factors that Affect Power Line Communication

3-1 Power Line Communication Issues

The micro inverter has a built-in power line communication module to support communication with the gateway.
The gateway includes the same module to communicate with the microinverter. LG AC module monitoring system
is designed to automatically achieve power line communication without additional configuration.
However, the gateway and microinverter are commonly connected to the same power source in a home or
building. As a result, other devices can affect the communication between the gateway and micro inverter, and
vice versa. This interference can lead to communication issues.
