STACKING MENU
The STACK (stacking) section is used to program the stacking of the FX’s. An explanation of stacking can be found in the STACKING
INFORMATION and STACKING INSTRUCTIONS sections of this manual. The FX’s can be connected in series, parallel or 3-phase for
higher voltage and/or higher power. There are four types of stacking available; ‘Classic Stacking’, ‘OutBack Parallel Stacking’,
‘OutBack Series Stacking’ and ‘3-Phase Stacking’. The programming of the “master” and “slave” units must be completed with the
inverters OFF in order to prevent possible problems.

Once the password has been correctly entered, the ADV - CHOOSE CATEGORY: screen is
displayed. Selecting shows a second screen of categories.
Selecting <PG3> shows a third screen of categories.
Selecting allows adjustment of the stacking set points and operation.
The STACK PHASE screen sets the hierarchy of the FX’s. If the system is to be stacked, a HUB
must be included and the FX that is to be the MASTER must be plugged into port 1 of the HUB. The
default for every FX is ‘1-2ph Master’. Pressing PORT will select the next port that a FX is plugged
into. When the port for the FX has been chosen, press INC until the proper master or slave type
appears (1-2ph Master, Classic Slave, OB Slave L1, OB Slave L2, 3ph Master, or 3ph Slave).
The POWER SAVE LEVEL MASTER ADJUST ONLY is used to set the number of ‘slaves’ that will
remain ‘On’ when the system is operating at light load levels. The value corresponds to the rank of
the SLAVE. For example, setting this value to 2 allows all SLAVE’s with POWER SAVE LEVEL
SLAVE ADJUST ONLY (see next screen) values of 2 or less to stay on at all times. This setting is for
“OutBack Stacking” methods only (system with “OB Slave L1” or “OB Slave L2” slaves).
The POWER SAVE LEVEL SLAVE ADJUST ONLY is used to set a slave inverter’s priority for
operation when the total FX system is operating at medium to heavy loads. By setting each of the
slaves to a different number you can control the sequence that the slave inverters are turned on by
the master inverter. This setting is necessary for “OutBack Stacking” methods.
Selecting TOP returns the user to the top of the ADV/FX/STACK menu section. Selecting ADV
returns you to the advanced screen to allow selection of another product connected to the MATE.
Selecting MAIN returns the display to the MAIN screen.
