New Appendix
Add the following appendix after Appendix C in the XW Power System
Installation Guide:
Appendix D XW Series Hybrid Inverter/Charger 120V/240V
Split-Phase to 120V Single-Phase Conversion Instructions
Converting from 120/240V split-phase to 120V single-phase is required in
systems with single-phase (2-wire 120V) or three-phase (208/120V) sources (such
as generators or grid). For a three-phase system, the loads may consist of singlephase loads or three-phase loads. Please refer to the wiring diagrams starting on
page 13. If you have questions, contact Xantrex customer service at
1-866-519-1470 or customerservice@xantrex.com.
Important: To complete the conversion, you must refer to instructions in the XW
Config User’s Guide (Document Part Number 975-0365-01-01). If you want to set up a
single-phase system, you must refer to instructions in the XW Series Hybrid Inverter/
Charger Operation Guide (Document Part Number 975-0240-01-01). If you do not have
these guides, download them from www.xantrex.com.

Converting 120V/240V Split-Phase to 120V Single-Phase
The following sections provide instructions on how to reconfigure a standard XW
120/240V, 3-wire model to accept 120V, 2-wire connection. To set up a threephase system using three XW 120V configured XW units, perform these steps for
all three inverter/chargers.
WARNING: Shock and Fire Hazard
:
Disconnect all AC and DC sources from the inverter/charger before removing the covers.
Failure to do so may result in damage to the inverter/charger or personal injury.
Parts and Tools Required
To complete the conversion, you will need one small jumper and three large
jumpers as shown in Figure 1. These jumpers are included in the packaging bag
shipped with each XW inverter/charger.
Figure 1 Jumpers
You will need a Phillips #2 screwdriver and may require other tools, as necessary.
Disconnecting Power Sources
To disconnect power sources:
1. Put the XW system in Standby mode using the System Settings menu on the
XW System Control Panel, but do not disconnect DC sources (for example,
batteries). Do not turn off the DC breaker.
2. Disconnect AC sources (such as the utility grid and generators) by turning off
the AC input breakers.
3. Turn off and disconnect all AC loads by turning off the AC output breaker.
Note: It is not necessary to remove the unit from its mounting position to perform the
following tasks.

Upgrading the Firmware
To upgrade the firmware, you must refer to instructions in the XW Config User’s
Guide (Document Part Number 975-0365-01-01). If you do not have this guide,
download it from www.xantrex.com.
To upgrade the firmware:
1. Acquire the USB-to-Xanbus™ adapter to connect the XW System to a PC
(Product Part Number 865-1155).
2. Download the USB-to-Xanbus adapter driver (available on
www.xantrex.com).
3. Connect the USB-to-Xanbus adapter to a USB port on your computer, and
then install the downloaded driver. See the XW Config User’s Guide for
detailed instructions.
4. Download and save the latest XW6048-120V firmware onto your computer
(available on the XW product page at www.xantrex.com).
8
976-0222-01-01

5. Make sure nominal DC voltage is present at the unit’s DC terminals.
6. Download and install the latest XWConfigPro to your computer (available on
the XW product page at www.xantrex.com).
7. Run XWConfigPro.
8. Select Convert from the XWConfigPro menu (see Figure 7), and then follow
the on-screen instruction to complete the conversion.
Figure 7 XWConfigPro
9. For future reference, record the new firmware version.
The conversion of one XW 120V/240V split-phase model to a 120V singlephase model is now complete.
• To set up a single-phase system, repeat the steps in “Converting 120V/
240V Split-Phase to 120V Single-Phase” starting on page 4 for up to
three more inverter/chargers, and then continue to “Setting Up a SinglePhase System” on page 10.
• To set up a three-phase system using three XW 120V single-phase
models, repeat the steps in “Converting 120V/240V Split-Phase to 120V
Single-Phase” starting on page 4 for two more inverter/chargers, and then
continue to “Setting Up a Three-Phase System” on page 10.

Setting Up a Single-Phase System
Before setting up a single-phase system, perform the steps in “Converting 120V/
240V Split-Phase to 120V Single-Phase” starting on page 4 to convert up to four
XW 120V/240V split-phase models to 120V single-phase models.
A maximum of four inverters can be installed in parallel for a single-phase
system.
Important: In a four-inverter system, a second XW PDP is required.
The XW Series Hybrid Inverter/Charger Operation Guide (Document Part
Number 975-0240-01-01) contains instructions for setting up a single-phase
system. After converting split-phase models to single-phase models, follow the
configuration instructions in the guide to set up a single-phase system.
Setting Up a Three-Phase System
Before setting up a three-phase system, perform the steps in “Converting 120V/
240V Split-Phase to 120V Single-Phase” starting on page 4 to convert three XW
120V/240V split-phase models to 120V single-phase models.
To set up a three-phase system:
1. Daisy chain XW-phA, XW-phB, and XW-phC at each unit’s AC sync port. To
do this, connect an AC sync cable between unit 1 and unit 2. Next, connect an
AC sync cable between the second AC sync port in unit 2 and an AC sync
port in unit 3. Network terminators are not required for AC Sync connections.
2. On the System Control Panel (SCP), select XW6048 00 > Advanced Settings
> Multiunit Config.
3. Change the device name or device number in the proper sequence.
4. Under Invtr Mode, select:
•
•
•
3Ph L1Master for unit 1 or Phase A
3Ph L2Master for unit 2 or Phase B
3Ph L3Master for unit 3 or Phase C
5. Optionally, up to one additional unit may be installed in parallel on each
phase. This allows for a maximum of 6 XW units in a three-phase system. The
second unit on each phase (parallel) must be configured as 3PhL1Slave,
3PhL2Slave, and 3PhL3Slave respectively. A maximum of two units per
phase is allowed.
Important: In a six-inverter system, a second XW Power Distribution Panel is
required.

976-0222-01-01
Addendum
CAUTION
Maximum power of 36kW is permitted in a standalone system where no grid is available.
If the system is tied to the grid, then total power during Sell mode must be adjusted so that
it does not exceed 30kW. The power adjustment on each phase must be made at time of
commissioning and under supervision of a utility representative.
6. Make sure the Grid or Gen wiring has the correct A, B, C phase sequence with
the three XW inverter/chargers. If the phase sequence is incorrect, the XW
system will not qualify the input AC voltage.
7. Put the wiring compartment cover back in place, and then power up the
converted units. Perform an AC voltage measurement in invert mode. Make
sure the output voltage is within 115 – 120 Vac.
When installed in a three-phase system, the XW inverter/charger checks for the
existence of a master on each phase. If there is not a master unit on each phase, a
system-wide fault (F66) is asserted. Each XW inverter/charger has to be
associated with a phase or line. To associate an XW inverter/charger with a phase
or line, select one of six available three-phase inverter modes shown in Table 2.

a.Each phase can support one master unit and one slave unit.
b.The L1 Master is also the master inverter/charger for the entire system. The system master broadcasts phase synchronizing pulses through its sync port, and each
phase master controls the other units on its respective phase.
c.The second unit in each phase is optional.
Note: Device numbers are only suggested to facilitate identifying devices on the system
as well as phase association from a device’s name and number. Customize the naming as
desired. Conflicting device names are allowed and will not cause faults in the system.
