side of the interface circuit board.

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».
