AC Wiring for a Dual-Inverter System
1. Disconnect the AC wires (from the utility grid or generator and to the
sub-panel) and remove the factory-installed distribution bars connected to
top and bottom terminals on the AC breakers.
2. Remove bypass interlock bracket.
3. Disconnect INV1 AC LOAD (INV1 L1-LOAD, INV1 L2-LOAD) wires from top
terminals on right-hand side breaker.
4. Add three additional dual-pole AC breakers (supplied in 865-1020) next to
the existing three dual-pole AC breakers.
5. Attach the four, four-tab distribution bars (supplied in 865-1020) to top and
bottom of AC breakers as shown in dual-inverter system wiring diagrams.
6. If a backup generator or other secondary AC source is installed in the
system, reuse two of the dual-tab power distribution bars previously installed
on INV1 Grid/Bypass breakers for generator breakers as shown Figure 2-28.
7. Connect grid wiring and loads/subpanel wiring to the new distribution bars
as shown in Figure 2-29.
8. Connect INV1 LOAD (INV1 L1-LOAD, INV1 L2-LOAD), INV2 LOAD (INV2
L1-LOAD, INV2 L2-LOAD), and INV2 GRID (INV2 L1-GRID, INV2 L2-GRID)
wires to AC breakers as shown in Figure 2-29.
9. Connect neutral (INV2 N-LOAD (SPLIT-PHASE)) and ground (INV2
GROUND) wiring as shown in dual-inverter system wiring diagrams.
10. Connect wiring at the inverter/chargers as shown in Figure 2-29.
11. Remove the knockouts on upper wire cover for additional breakers to fit
through.
12. Re-install upper wire cover. Relabel the AC breakers with the appropriate
labels provided with the Xantrex XW Power Distribution Panel.
13. Install bypass interlock plate with provided screws and nylon shoulder
washers (supplied in 865-1020).
