Xantrex Xanbus and AC Sync Cable
A Xantrex Xanbus and AC sync cable is required for multi-unit installation.
The AC sync cable connects each inverter, and provides the necessary
communication and control between multiple units.
Install these cables, routing it through the Xantrex XW Conduit Box raceway, prior
to making the AC and DC wiring connections. See Figure 2-35.
Figure 2-35 Installing the AC Sync Cable

To install the AC Sync and Xantrex Xanbus cables between inverters:
Remove the two
factory-installed raceways
for the communication
cabling by removing the
screw holding each
raceway in place.
Insert the RJ45 jack
on the cable into
one of the two AC
Sync ports.
Route the cable as shown. Route any additional
communication cables through the raceways.
Replace the wiring raceways, ensuring not to
pinch the cables. Secure the raceways to the
Xantrex XW Conduit Box with the screw that
was removed earlier.
IMPORTANT:
In a 2-inverter system, install an AC Sync Cable from
INV1 to INV2.
In a 3-inverter system, “daisy-chain” an AC Sync
Cable from INV1 to INV2 and from INV2 to INV3.
Do NOT install terminators in an AC Sync Port.
