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
than62 it isnecessary touse the secondRS485/2port respectingthe samewiring diagramused for
themainRS485/1port.
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: When connecting multiple units (string inverter or/and 55kW conversion modules) it is necessary
towiretheRS485communicationlineaccordingtothedaisy-chaindiagram(enter-exit).

Note: In case of mixed systems, the presence of both string inverters and central inverters on the same
RS485lineispermitted.Towirethislinefollowallthedirectionsabove.
Note: For further details on the wiring of the RS485 line and/or the activation of the termination
resistances,refertotheusermanualofstringinvertersandtotheusermanualofcentralinverters.
Note: All string inverters (except for models PVI-5000/6000-TL-OUTD) have a clamp that allows giving
continuitytothecableshieldoftheRS485line.
For single-phase inverters this clamp is indicated by the words LNK,for three-phase inverters it is
indicatedbySCLD.

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 portionof communication line.(must notbe given continuity to
thecableshield).
