Ad (5): Local Link for up to 99 Solar
Inverters
With this interconnection, up to 99 Solar
Inverters can be cross-linked and read out.
That results in a maximum RS485 cable
length of 500 m between the Solar
Inverters and the interface transformer.
The RS485 signal is transferred from the
first Solar Inverter in the row into the

interface transformer with the following
allocation: «RS485 +» to «DATA+» and
«RS485 -» to «DATA-».
The interface transformer transforms the
RS485 signal into RS232. It is linked to the
PC with cable type 2 (standard modem
cable). With the Solar Inverter that is fur-
thest away from the interface transformer,
the jumper RS485 MATCH must be closed.
