Conext XW Pro Installation Guide

7. Check inverter display for startup self-test during which LEDs will flash momentarily.
Once self-test is complete, the inverter will display Stb. If the inverter has been pre-
configured, it may go straight into normal operating mode or display F66 warning.
8. Using the Conext Gateway, set the Second (Slave) Inverter Device Number and
Inverter Mode:
a. Select the new inverter XW6848, instance in the device page.
b. Go to the inverter’s Configuration page and enable Advanced View.
c. Under Device Instance set Device Number to 2 (or the next unused
number).
d. Click Apply. The inverter will now appear as instance 2 in the device list.
e. Under Multi-unit Configuration, set Inverter Mode to Split
Phase Slave.
f. Click Apply.
9. Check for events. If events 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 Gateway, enable the system by going to the Devices page, and
next to System Operating State, click Operating.
12.
Confirm the Master inverter displays 0.00 and the Slaves displays “---” on their front
panels.
13. Check for events. If events exist, correct, and then restart Functional Test.
14. Check voltage at AC LOAD terminals of the Master inverter.
15. Switch the AC Load breakers ON.
16. Confirm operation of connected AC loads.
Note: If oscillation occurs, perform the "XW+/XW Inverter/Charger Multi-Unit AC
Output Voltage Configuration and Calibration" in Appendix A of the Conext XW Pro
Multi-unit Power System Design Guide (990-91373).
17. Disconnect AC LOAD breakers.
18. Using the Conext Gateway, reduce maximum charge rate.
a. From the Conext Gateway web application, enable Cascading (if not
enabled). With Cascading enabled, a change to a setting in one inverter will
automatically ripple through to the other inverter(s) in the system.
b. In the inverter’s Configuration page, under Charger Settings set
Maximum Charge Rate to 10%.
c. Click Apply.
19. Switch AC input breakers ON.
Note: All inverters in the system must be connected to the same AC input source
before they will qualify the source.
