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.
