12. Confirm Master inverter displays "0.00" and Slave(s) displays "---" on their front
panels.
13. Check for faults. If fault condition(s) exist, correct and 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 XW System Control Panel, reduce Maximum Charge Rate.
a) From 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 auto-
matically 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 the 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 restart Functional Test.
If the Inverters pass the Functional Test, proceed to Commissioning procedure as defined
in XW Inverter/Charger Operation Guide.
