Ad (6): Remote Link for up to 99 Solar

Inverters

If you wish to connect several Solar Inverters to the remote monitoring system, the individual Solar Inverters must be cross- linked via RS485. The RS485 signal of the first Solar Inverter in the row is transferred into the interface transformer with the fol- lowing allocation: «RS485 +» to «DATA+» and «RS485 -» to «DATA-». Connect the remote modem to the interface transfor- mer. With the last Solar Inverter, the jum- per «RS485 MATCH» must be closed. With all other Solar Inverters, it has to be in the open position.

￿!

To identify the individual Solar Inverters,

a clear RS485 has to be assigned to each of them. See chapter «Setting the RS485 Address».

Finding the Jumper «RS485 MATCH»

in the Solar Inverter

Please make sure the jumper «RS485 MATCH» is in the right position, considering the communication interconnection you have chosen. This jumper is on the under- side of the interface circuit board.
