Rs485 Bus Configuration; Verifying The Connection - SolarEdge StorEdge SE5K-RWS Installation Manual

55 RS485 Bus Configuration
10. If no surge protection is used, connect the grounding wire to the first inverter in the
RS485 chain; make sure the grounding wire is not in contact with other wires. For
inverters with a StorEdge Connection Unit, connect the grounding wire to the
grounding bus-bar in the StorEdge Connection Unit.

RS485 Bus Configuration

To connect to the monitoring platform:
1. Designate a single inverter as the connection point between the RS485 bus and the
monitoring platform. This inverter will serve as the leader inverter.
2. Connect the leader to the monitoring platform using Ethernet (refer to Creating an
Ethernet (LAN) Connection above).
To configure the RS485 bus:
All inverters are configured by default as followers. To configure the leader:
1. Make sure the inverter's ON/OFF/P switch is off.
2. Make sure that the AC circuit breaker on the main distribution panel is on.
3. Access SetApp, as described in Communication on page 43.
4. From the Commissioning screen, select Site Communication > RS485-2 > Protocol
> SolarEdge > SolarEdge Leader.
5. Return to the RS485-2 screen and select Follower Detect.
The system starts automatic detection of the follower inverters connected to the
leader inverter. The inverter should report the correct number of followers. If it does
not, verify the connections and terminations in all inverters in the chain.
6. To check the follower IDs and last communication time, select RS485-2 > Follower
List.
7. Verify the connection of the leader to the monitoring platform, as described below.

Verifying the Connection

After connecting and configuring a communication option, perform the following
steps to check that the connection to the monitoring server has been successfully
established.
1. Access SetApp and select Commissioning > Status.
2. In the Summary section, under Server Comm., make sure S_OK is displayed
together with the selected communication option.
