Three topologies of ethernet connection to the router are available:
Ring configuration
ROUTER
Daisy chain configuration
ROUTER
Star configuration
ROUTER
NOTE – D The ring configuration is the preferred method to connect multiple units in order to
allow reaching inverters also in case of single unit failures.
NOTE – D In case inverters are connected to the networking switch with a ring topology is
recommended to enable SPT protocol on the switch (Spanning Tree Protocol SPT (IEEE 802.1D)
is enabled by default on inverters).
NOTE – D On each configuration the maximum length of the cable must be 100m between
inverter – inverter and inverter – switch.
NOTE – D For further information on the Ethernet connection refer to the Local Area Network
standard IEEE802.3
NOTE – D No initial setup is required to start data transmission to Aurora Vision.
NOTE – D Internet connection is required to use all the Aurora Vision remote functionalities.
NOTE – D Please refer to Aurora Vision documents available on ABB website for further
information how to get an Aurora Vision account for remotely monitoring and managing the
installed solar assets.
