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 73
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a shielded Ethernet cable
(Cat5/5E STP) may be used)
Wire cross-section : 0.2- 1 mm²/ 24-18 AWG
Maximum distance between first and last devices: 1 km /3300 ft.
The following sections describe how to physically connect the RS485 bus and how to
configure the bus.
