Configuration of DC input Groups
The configuration of the DC input to the inverters provides several different ways to monitor DC input
power and input current.
For bulk monitoring, assign all inverters to DC Input Group 1.
For a system with two or more battery strings, refer to the power system manual for specific configuration
details.

6.4.3 Set Output
Set the number of inverters in each phase of your
system. Match the AC input phase to the correspond-
ing AC output phase.
1. Number of Modules: Enter the total number
of inverter modules that will be installed for that
phase.
2. Redundancy: Enter the number of inverter
modules that will provide redundant power for
that phase (used to provide system warnings).
3. Phase Shift : Enter the phase shift for each
output group in your system configuration
1 2 3
Single phase ° 0 N/A N/A
Split phase (120/240 V) ° 0 180 N/A
2-pole (120/208) ° 0 120 N/A
3-phase (120/208 V) ° 0 120 240
4. Nominal Output Voltage : Enter 120 for all
phases.
5. Press Submit.
CAUTION!
The value entered in the Nominal Output Voltage field can change the actual AC output volt-
age of the inverters. Setting this value to anything other than 120 V will render the UL/CSA
approval invalid.
