Basic Functional Test-Multiple Inverters - Xantrex XW4024 230 50 Installation Manual

Inverter/Charger Installation
Basic Functional Test—Multiple Inverters
2–34
The following steps perform a basic functional test of multiple Xantrex XW
Inverter/Chargers. If any test fails, refer to the Troubleshooting section in the
Xantrex XW Hybrid Inverter/Charger Operation Guide for assistance.
To perform a functional test on multiple inverters:
1. Check/verify all wiring and cable connections.
2. Measure DC voltage at the DC terminals on the inverter and confirm that it is
within range and has correct polarity. The default acceptable range is 23–32
VDC for 24 V systems or 46–64 VDC for 48 V systems.
3. Connect DC power to the first inverter.
4. Check the inverter's display for startup self-test during which all LEDs will
flash momentarily. Once the self-test is complete, the inverter displays
The Fault/Warning LED may flash for a few seconds but eventually will turn
off. If the Fault/Warning LED persists, make sure the battery temperature
sensor is connected. Also, if the inverter has been pre-configured, it may go
straight into normal operating mode.
5. Using the Xantrex XW System Control Panel, set the first (Master) inverter's
device number.
a) Go to the inverter's Advanced Settings menu by pressing the down
arrow, and then Enter from System Status screen. Next, simultaneously
press Enter + up arrow + down arrow.
b) Select the Multi Unit Config menu.
c) Change Dev Number from "00" to "01". The inverter will now appear as
XW6048 01 (or XW4548 01 or XW4024 01) on the Xantrex XW System
Control Panel.
d) If performing a test on a three-phase installation, change Invtr Mode to
"3Ph L1Master." For more information, see "Three Phase Configuration"
in the Xantrex XW Hybrid Inverter/Charger Operation Guide.
e) Press Exit until the Xantrex XW System Control Panel displays the System
Status screen again.
6. Connect DC power to the next inverter.
7. Check the inverter display for startup self-test during which all LEDs will flash
momentarily. Once the self-test is complete, the inverter displays

mode or display
8. Using the Xantrex XW System Control Panel, set the second (Slave) inverter's
device number and inverter mode.
a) Select the new inverter XW6048 00 (or XW4548 00 or XW4024 00) from
the Select Device menu. You can also press the down arrow from the
System Status screen until the home screen for Xantrex XW Inverter/
Charger 00 is displayed, and then press Enter.
b) Go to the inverter's Advanced Settings > Multi-Unit Config menu.
c) Change Dev Number from "00" to "02" (or the next number that has not
been used). The inverter will now appear as XW6048 02 (or XW4548 02
or XW4024 02) on the Xantrex XW System Control Panel.
