Creating An Rs485 Bus Connection - SolarEdge SE3000 Installation Manual

Creating an RS485 Bus Connection

The RS485 option enables you to create a bus of connected inverters. 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.
