21. Use the CXCU GUI as follows to verify that the modules are recognized and the voltages and

currents of the modules are displayed. (Ignore any alarms at this point. The current readings at

no load are not very precise.)

a. Select Inverters > View Live Status.

b. In the Inverter Report screen, locate the module for AC phase 1 by clicking each row until

the LEDs of the inverter, in the ﬁrst phase 1 shelf, ﬂash for a few seconds.

c. Using the pull down box in the Module Nu mber column, set the module number to 1 to

correspond to AC phase 1.

d. If this is a multiple phase system,locate the module for AC phase 2 by clicking each row in

the Inverter Rep ort screen until the LEDs of the inverter, in the ﬁrst phase 2 shelf, ﬂash for a

few seconds.

e. Use the pull down box to set the module number to 2 to correspond to AC phase 2 (for split

phase, 2-pole and 3 phase systems).

f. Repeat for a third module (select 3 to correspond to AC phase 3) if the system is 3 phase.
