Basic Functional Test - Multiple Inverters
The following steps will complete a basic functional test of multiple Conext XW+
Inverter/Chargers. If any test fails, please refer to the Troubleshooting section in
the
Conext XW+ Inverter/Charger Owner’s 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 it is
within range and has correct polarity. The default acceptable range is 46 to
64 VDC for 48 V systems.
3. Switch INV1 DISCONNECT to the ON position.
4. Check inverter display for startup self-test during which LEDs will flash
momentarily. Once self-test is complete, the inverter will display .
(The Fault/Warning LED may flash for a few seconds but eventually will turn
off. If Fault/Warning LED persists, check to make sure a battery temperature
sensor is connected. Also, if the inverter has been pre-configured, it may go
straight into normal operating mode.)
5. Using the Conext System Control Panel, set the First (Master) Inverter Device
Number:
a) Go to the inverter’s Advanced Settings menu by pressing Down
arrow + Enter from the System Status screen and then simultaneously
pressing Enter + Up arrow + Down arrow.
b) Select Multi Unit Config menu.
c) Change Dev Number from 00 to 01. The inverter will now appear as
XW6848-01 in the device list.
d) Press Exit to go back to the System Status screen.
6. Switch INV2 DISCONNECT to the ON position.
7. Check inverter display for startup self-test during which LEDs will flash
momentarily. Once self-test is complete, the inverter will display . (If the
inverter has been pre-configured, it may go straight into normal operating
mode or display F66 warning.)
8. Using the Conext System Control Panel, set the Second (Slave) Invert er
Device Number and Inverter Mode:
a) Select the new inverter, XW6848-00, in the device list.
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 XW6848-02 in the device
list.
d) Change Invtr Mode from SplitPhMaster to SplitPhSlave.
e) Press Exit until you see the System Status screen.
9. Check for faults. If fault condition(s) exist, correct and restart Functional Test.
10. If a third inverter is installed, repeat steps to configure it as a Slave.
11. Using the Conext System Control Panel, enable the system:
a) Go to the System Settings menu.
