57 RS485 Bus Configuration

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. Turn on the DC Safety Unit.
4. Turn on the DC Safety Unit (if applicable).
5. Access SetApp, as described in Communication on page 42.
6. From the Commissioning screen, select Site Communication > RS485-1 > Protocol
> SolarEdge > SolarEdge Leader.
7. Return to the RS485-1 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.
8. To check the follower IDs and last communication time, select RS485-1 > Follower
List.
9. 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. If the DC Safety Unit cover is not closed, close it: Attach the DC Safety Unit cover
and secure it by tightening the screws with a torque of 10.3 N*m/ 7.6 lb.*ft.For
proper sealing, first tighten the corner screws and then the two central screws.
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.
