Communication between the BMS and Battery Modules
The communication connections must be arranged for each tower as indicated in section 2.1.2.1, using
the communication cables between the battery modules:
Link port 1 of the BMS to link port 0 of the first battery
Link port 1 of the first battery must be connected to link port 0 of the second
…
Link port 1 of the second-last battery must be connected to the last battery.
BMS – Inverter communication
The two BMS must be set with a different address by changing the position of the dip switches, as
shown below:
Address 000000 = address 0 (to be assigned to tower 1)
Address 100001 = address 1 (to be assigned to tower 2)
The RJ45 cable of the BMS with Address=1 (tower 2) will depart from the link port B of the
CAN/RS485 input and connect to the link port A of the CAN/RS485 input of the BMS with Address=0
(tower 1); finally, another cable must be inserted in link port B of the same BMS and must be
connected to the COM of the inverter, according to the indications in section 2.1.2.2.
