Network Topology

Up to ten SMA String-Monitors can be connected to each string monitoring communication connection of the inverter

in line topology (number of connections for string monitoring communication see the inverter manual).

Position

The SMA String-Monitor is equipped by default with Ethernet communication. Distances of up to 100 m between two

nodes can be bridged via Ethernet. The SMA String-Monitor can be retrofitted with optical fiber communication, if

required (see Section 8, page 24). Distances of up to 2,000 m between two nodes can be bridged via optical fiber

communication.

Both communication types can be combined between two SMA String-Monitors, meaning that you can use Ethernet

communication and/or optical fiber communication for the communication input and for the communication output

depending on the distance to be bridged.
