CAUTION!
The value entered in the Nominal Output Voltage field can change the actual AC output
voltage of the inverters. Setting this value to anything other than 120 V will render the UL/
CSA approval invalid.
Number of Modules Total number of inverter modules installed for that phase. Setting this number to
something different from the actual number of installed modules results in the
alarm condition Inverter Comms Lost .
Redundancy Defines the number of inverter modules that will provide redundant power for that
phase (used to provide system warnings).
Phase shift Assigns a phase shift (in degrees) to the AC output group.
Nominal Output Voltage Enter 120 for all phases.
Ensure that the Phase Shift is set correctly before mapping inverters in the new groups and turning them on.
