Creating an RS485 Bus Connection

The RS485 option enables creating a bus of connected inverters, consisting of up to 31 slave inverters and
1 master inverter. Using this option, inverters are connected to each other in a bus (chain) via their RS485
connectors, thus allowing to connect only the master inverter to the monitoring platform. The first and
last inverters in the chain must be terminated as described in RS485 Bus Configuration on page 64
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a shielded Ethernet cable (Cat5/5E STP) may be used)
l
Wire cross-section : 0.2- 1 mm²/ 24-18 AWG
l
Maximum distance between first and last devices: 1 km /3300 ft.
l
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
