Parts List for Dual-Inverter Configurations

Installing an additional inverter using the power distribution panel requires an XW

Connection Kit (part number 856-1020), which contains the following components:

•XW Conduit Box

•Three 60 amp, 120/240 VAC, 2-pole, Square-D Type QOU, DIN-rail mount, AC breakers for Inverter Input, Output, and Bypass

•Four Power Distribution bars

•Custom Bypass Interlock

•#6 AWG AC wiring to connect the inverter to AC breakers

•GJ250A, 160VDC, 3/8" Stud, DC Breaker with copper bus bar for DC positive

•one pair #4/0 battery cables to connect the inverter to DC breakers

•Xanbus and AC Sync Cable (CAT 5 cable with RJ45 connectors wired to T568A standard).

•Miscellaneous bushings

Important: When installing more than one inverter at a location, a XW System Control Panel will be required to give each inverter (as well as other Xanbus-enabled devices) a unique name and to modify the factory-installed default settings to match and support the installed configuration.

Converting a Single-Inverter Power Distribution Panel to a Dual-Inverter Power Distribution Panel

◆Remove upper wire cover and lower wire cover on the XW Power Distribution Panel.

DC Wiring for a Dual-Inverter System

1.Remove positive distribution plate attached to bottom terminal on existing DC disconnect/breaker.

2.Install second DC disconnect/breaker (supplied in 865-1020) next to existing DC disconnect/breaker.

3.Replace the factory-installed DC positive bus bar with the larger positive bus bar provided in the 865-1020. This larger DC positive bus bar supports up to three GJ250 Adc disconnect/breakers.

4.Connect positive battery cable for second inverter (supplied in 865-1020) to top terminal on second DC disconnect/breaker.

5.Connect negative battery cable for second inverter (supplied in 865-1020) to DC negative distribution plate.

6.Connect positive and negative battery cables to second inverter.

7.Remove knockout on the lower cover for additional disconnect/breaker to fit through.

8.Re-install lower wire cover.
