Power One AURORA PVI-AEC-EVO Guide D'installation Rapide page 10

Note: For PVI-AEC-EVO LIGHT, the inverters must be set with addresses: 1, 2, 3, 4, 5. The configuration of
address 1 corresponds to "AUTO" settings as inverter address.
Note: When connecting multiple units (string inverter or/and 55kW conversion modules) it is necessary
to wire the RS485 communication line according to the daisy-chain diagram (enter-exit).
The last inverter of the daisy-chain must be 'terminated' by activating the termination resistance of
Ω
the 120 communication line through switching the dip-switch located on the motherboard in the
string inverters,and inside each framework of the central inverters.
Note: The maximum number of units (string inverters or/and 55kW conversion modules) that can be
connected to a RS485 port of the PVI-AEC-EVO is 62. In order to connect a number of units greater
than 62 it is necessary to use the second RS485/2 port respecting the same wiring diagram used for
the main RS485/1 port.
In the PVI-AEC-EVO LIGHT the number of inverters that can be acquired is limited to a maximum of 5
strings inverters which can be connected by RS485/2 (Ref. Par. D). Compatible models (in every their
variation) for the PVI-ACE-EVO LIGHT version are: PVI-2000(-OUTD); UNO-2.0/2.5-I-OUTD; PVI-3600;
PVI-3.0/3.6/4.2-TL-OUTD; PVI-3.8/4.6-I-OUTD; PVI-5000/6000-TL-OUTD; PVI-10.0/12.5-TL-OUTD;
PVI-10.0/12.0-I-OUTD.
Note: In case of mixed systems, the presence of both string inverters and central inverters on the same
RS485 line is permitted.To wire this line follow all the directions above.
Note: All string inverters (except for models PVI-5000/6000-TL-OUTD) have a clamp that allows giving
continuity to the cable shield of the RS485 line.
For single-phase inverters this clamp is indicated by the words LNK, for three-phase inverters it is
indicated by SCLD .
Note: The centralized inverters have a clamp, which is located in the signal terminal block and marked
with "X23", that allows to link to ground the shield of each singular portion of the communication
line independently from the other portion of communication line. (must not be given continuity to
the cable shield).
Note: For further details on the wiring of the RS485 line and/or the activation of the termination
resistances,refer to the user manual of string inverters and to the user manual of central inverters.
