Figure 32: RS485 termination switch
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. Ifnotusingsurgeprotection,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SafetySwitch,
connectthegroundingwiretothegroundingbus-barintheSafetySwitch.
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masterinverter.
2. ConnectthemastertothemonitoringplatformviatheLANoption(referto)oranyoftheother
options.
To configure the RS485 bus:
Allinvertersareconfiguredbydefaultasslaves.Toconfigurethemaster:
1. VerifytheON/OFF/PswitchisOFF.
2. VerifythatACison.
3. UseSetApptoaccesstheCommissioningmenuscreenasdescribedinCommunicationonpage35.

Selectthefollowingtoconfiguretheconnection:
l ServerèLAN
l RS485-1èProtocolè SolarEdge Master
l RS485-1èSlave Detect
Thesystemstartsautomaticdetectionoftheslaveinvertersconnectedtothemasterinverter.The
invertershouldreportthecorrectnumberofslaves.Ifitdoesnot,verifytheconnectionsand
terminations.
6. TochecktheslaveIDsandlastcommunicationtime,selectRS485-1èSlave List.
7. Verifytheconnectionofthemastertothemonitoringplatform,asdescribedinthenextsection.
