Figure 2-31 DC Connections for a Triple-Inverter System
AC Wiring for a Triple-Inverter System
1. Prepare power distribution bars (supplied in 865-1020) by cutting away one
of the four tabs, only three tabs per power distribution bar are required in a
three inverter system. A total of 4 distribution bars should be prepared for a
single AC source and 6 distribution bars for a dual AC source.
2. Mount the nine breakers on the din rail and install power distribution bars as
follows (refer to figures 2-28 & 2-29):
a) Two distribution bars, L1 and L2 at the input (top) terminals of the INV1,
INV2 and INV3 Grid breakers.
b) If the installation includes a second AC source, install two distribution
bars, L1 and L2 at the input (top) terminals of the INV1, INV2 and INV3
Gen breakers.
c) Two distribution bars, L1 and L2 at the output (bottom) terminals of the
INV1, INV2 and INV3 AC Load breakers.
Actual cable requirements may vary.
Torque connections to
the battery terminals
according to the
battery manufacturer’s
recommendations.
Torque connections to the inverter DC
terminals to 10-15 ft/lbs.
AC Breakers shown in this illustration
represent the breaker arrangement for
multiple AC source.
Power Distribution bars in the Xantrex XW Power Distribution Panel
accept up to a #2/0 AWG cable (maximum).
See Figure 2-9 on page 2–14 for torque requirements.
