RS485

Also known as RS-485, EIA-485, TIA/EIA-485

RS485 (Recommended Standard 485) is a wired serial communication interface used by compatible inverters, meters, data loggers and controllers to exchange data over differential signal lines.

RS485 (Recommended Standard 485), also written RS-485, is a wired serial communication interface that uses differential signalling so compatible devices can exchange data over a shared cable run. In home energy systems it may appear on inverter, battery, meter, data logger or gateway terminals for links such as Modbus RTU (remote terminal unit), meter communication, export-control metering or monitoring data.
