SolarEdge SE66.6KUS - RS485 Bus Connection

7.
ConnectthecableRJ45connectortotheRJ45portoftheEthernetswitchorrouter.
Youcanconnectmorethanoneinvertertothesameswitch/routerortodifferentswitches/routers,
asneeded.EachinvertersendsitsmonitoreddataindependentlytotheSolarEdgemonitoring
platform.
NOTE
There are no LED indicators on the Ethernet connector, if the inverter is not communicating with
the monitoring platform through a LAN refer toTroubleshooting Communication on page 73.
8.
TheinverterisconfiguredbydefaulttoLAN.Ifreconfigurationisrequired:
a. VerifytheON/OFFswitchisOFF.
b. VerifytheACison.
c.
ClosethecoverandturnONtheConnectionUnit.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the Connection Unit
cover is removed.
RISQUE D’ÉLECTROCUTION, ne touchez pas les fils non isolés lorsque le couvercle de
l'onduleur est retiré.

NOTE
The system automatically establishes communication with the monitoring platform as it is
configured to LAN by default.
NOTE
If your network has a firewall, you may need to configure it to enable the connection to the
following address:
l Destination Address: prod.solaredge.com
l Modbus TCP Port: 22222 (for incoming and outgoing data)
Creating an RS485 Bus Connection
TheRS485optionenablescreatingabusofconnectedinverters,consistingofupto31slaveinvertersand
1masterinverter.Usingthisoption,invertersareconnectedtoeachotherinabus(chain)viatheirRS485
connectors,thusallowingtoconnectonlythemasterinvertertothemonitoringplatform.Thefirstand
lastinvertersinthechainmustbeterminatedasdescribedinRS485BusConfigurationonpage67
RS485wiringspecifications:
