11. Using the Conext System Control Panel, enable the system:
a) Go to the System Settings menu.
b) Change System Mode to Operating.
c) Press Exit until you see the System Status screen.
12. Confirm the Master inverter displays . and the Slaves displays “” on
their front panels.
13. Check for faults. If fault condition(s) 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.
17. Disconnect AC LOAD breakers.
18. Using the Conext System Control Panel, reduce maximum charge rate.
a) From the System Status screen, go to System Settings and
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) Go to Advanced Settings > Charger Settings in one of the
inverters.
c) Set Max Chg Rate to 10%.
d) Press Exit until you see the System Status screen.
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.
20. Confirm both inverters start charging.
Note: With Max Chg Rate set to 10% the maximum charge rate is limited to
10 A on each inverter. Depending on the battery bank’s state-of-charge, the
output from one or more inverters may quickly drop to zero. This is
considered normal operation.
21. Check for faults. If fault condition(s) exist, correct, and then restart the
Functional Test.
If the Inverters pass the Functional Test, proceed to the Commissioning
procedure as defined in Conext XW+ Inverter/Charger Owner’s Guide.
