Connection of the multi-inverter communication
The multi-inverter communication takes place through the connectors indicated in Table 11. The connection must be
made by connecting together the corresponding pins on different inverters (e.g. pin 1 of inverter A on in 1 of inverter B,
etc.). It is recommended to use twisted and shielded cable. The shield must be connected on both sides to the central
pin of the connector.
Maximum recommended length of the communication cable between two inverters L: 5m.
Total maximum recommended length (sum of the lengths of all the communication cables): 20m.
