RS485 INTERFACE

SMA RS485 Interface – Part Number MD.485-41

The SMA RS485 Interface, referenced as MD.485-41, is a genuine spare part intended for compatible SMA inverters. It establishes a serial communication link using the RS485 protocol, a widely adopted industrial standard in both residential and commercial photovoltaic installations for remote monitoring and data acquisition.

Function and Application

The RS485 protocol is a robust, industry-standard communication method known for reliable data transmission over extended distances and support for multi-point network topologies. By fitting this interface to your SMA inverter, you enable the transfer of production data to a compatible energy management system, datalogger, or monitoring software.

This interface is well suited to professional installers integrating SMA inverters into centralised supervision infrastructures, as well as end users operating monitoring systems that require a wired RS485 connection.

Genuine SMA Spare Part

As a genuine SMA component, the MD.485-41 interface ensures full compatibility with SMA equipment. Using original parts is recommended to maintain installation performance and to preserve any applicable manufacturer warranty conditions on your inverter.
