Manual Energy Storage Inverter ESI-S
Commissioning instructions 155
In a multi-inverter arrangement, the address of each unit has to be set to a unique value.
Setting two units in the same system to the same address will lead to a conflict and will
inhibit the system from running.
In a system consisting of more than one unit, the inverter with the lowest address will
be considered as the first unit in the chain. The inverter with the highest address will be
considered as the last unit in the chain:
−
In master-slave inverter arrangements, it is recommended to assign the lowest
address to the master unit and increment the address by 1 for the next slave etc.
−
In master-master arrangements, the lowest address must be assigned to the
master unit that is considered as the main controlling unit. When the main master
unit is faulty, the master unit with the next lowest address will become the main
controlling unit.
In order to set the address of each unit in a system, the DIP switch module on the control
board has to be set accordingly.

control board (Item 22 in the figure).

Figure 80: Location of the inverter identification DIP switch on the control board (Item 22)
The inverter identification DIP switch consists of 4 switches that can be put in low or
high position (facing the board with the ABB logo at the top left side). The three left
hand DIP switches determine the unit address.
shows the unit addresses that
can be chosen and the corresponding configuration to be set.
