4.6.6 Communications sockets
The SolarMax MT series inverters have two RJ45 sockets for data communication within
a MaxComm network:
The left-hand RJ45 socket is only an RS485 interface. The RS485 interface is used
for connections to other SolarMax inverters or accessories with MaxComm
interface.
The right-hand RJ45 socket can be used both as an RS485 and as an Ethernet inter-
face; the desired function can be toggled in the “Settings” menu. The Ethernet inter-
face is used for connecting an inverter directly to a PC or to MaxWeb xp. However, if
both sockets are congured as RS485 interfaces, a network containing several
RS485 nodes can be set up.
NOTE
If the RJ45 sockets are used and the inverter is exposed to the weather, please use
products from the VARIOSUB-RJ45 range with IP67 protection class from Phoenix
Contact. This ensures that the installation meets the requirements of IP65.
RJ45 plug-in connector, 8-pin (item no. 1658493)
