Figure 3-41 RS485 Connection of Standard wirebox
3.4.3. RS485 Network Set-up
When the inverters are monitored via the RS485 communication, a unique RS485
address for each inverter can be set up through the LCD interface. Up to 32 inverters
can be connected in the RS485 communication network. The daisy-chain topology is
recommended for the RS485 network connection to minimize noise and bus
reflections, as shown in
Figure 3-42
. Other communication topologies, such as the
star networks, are not recommended. All RS485 connections must be terminated
in a serial fashion and not to exceed 32 in total.
