Figure 36: 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CreatinganEthernet

(LAN)Connectiononpage54)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.

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.
