Multiple SmartLoggers can converge over an Ethernet switch and then connect to an NMS.
The SmartLogger connects to the Ethernet switch over optical fibers with the maximum
communications distance of 12 km in between.
LTE+RS485/PLC Networking
shows the LTE+RS485/PLC network diagram.
In the LTE wireless networking scenario, the SmartLogger connects to the inverter over an
RS485 communications cable or an AC power cable, connects to a box-type transformer over
an RS485 communications cable or an Ethernet network cable, connects to southbound
devices such as the EMI and electricity meter over RS485 communications cables, connects
to customer-premises equipment (CPE) over an Ethernet electrical port, and transmits
information collected from southbound devices to an NMS in wireless mode.
