Creating an RS485 Bus Connection
The RS485 option enables you to create a bus of connected inverters (consisting
of up to 30 Slave inverters and 1 Master inverter). Using this option, inverters are
connected to each other in a chain, meaning the first inverter in the chain is
connected to the next inverter in the chain via its RS485 connector. The first
inverter in the chain and the last inverter in the chain must be terminated.
Figure 42: Example of RS485 Bus Connection
Each inverter must be connected according to the instructions below.
