Rs485 Bus Configuration - SolarEdge SE K Series Installation Manual

NOTE
Only the first and last SolarEdge devices in the chain should be terminated.
The other inverters in the chain should have the termination switch OFF
(down position).
11. Tighten the nut of the COMM2 gland in a torque of 3 lb*ft.

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. The leader is the inverter connected
to the Home network and the one that the meter MUST be connected to. 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 79.
4. From the Commissioning screen, select Site Communication > RS485-1 > Protocol
> SolarEdge > SolarEdge Leader.
5. 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.
6. To check the follower IDs and last communication time, select RS485-1 > Follower
List.
7. Verify the connection of the leader to the monitoring platform, as described below.
