Used for three-phase OutBack stacking with
FX, VFX, FX(E) or VFX(E) inverters.
For these applications, place only two jumpers
in the positions noted in the photograph
and the diagram.
Remove all remaining jumpers. No others are
used for this configuration.

Used for Subphase Master stacking in FX
and GS inverters (both three-phase and
series configurations).
For these applications, place all jumpers
in the positions noted in the photograph
and the diagram.
NOTE: This option requires MATE3
firmware revision 002.013.000 or higher.

This is the factory-installed initial position.
Used for classic series, OutBack series, and
parallel stacking. Also used for three-phase
OutBack stacking with models GVFX(E) and
GTFX(E) .
For these applications, place all jumpers in
the positions noted in the photograph and

Series Stack (OutBack)
Up to 10 inverters or other devices; requires balancing transformer
Master inverter and half of the Slave inverters use common output AC bus (L1)
The remaining Slave inverters use a separate common AC bus (L2)
Master inverter is always active; regulates output based on load;
can power both L1 and L2 buses using balancing transformer
Slave inverters remain in Power Save mode; Master activates
any Slave inverters for either L1 or L2 based on load
Series Stack (Classic)
2 inverters; up to 8 other devices
Master and single Slave inverter use separate output AC buses
(L1 and L2)
Both inverters always active
(no Power Save mode);
outputs are loaded independently
but output regulation is controlled
by load on Master

Series Stack (Subphase Master)
Up to 8 inverters (ports 1 to 4, 7 to 10); 2 other devices (ports 5, 6); No balancing transformer required
Master inverter and half of the Slave inverters use common output AC bus (L1); ports 2 to 4 are L1 slaves
Subphase Master inverter and half of the Slave inverters use a separate common AC bus (2); ports 8 to 10
are L2 Slave inverters despite the screen selection (OB Slave L1)
Port 7 is the L2 Subphase Master despite the screen selection (Classic Slave); this port is required
regardless of the number of Slave inverters
Master and Subphase Master are always active; each type of Master regulates output based on its own load
Slave inverters remain in Power Save mode; Master activates L1 Slave inverters based on its load, while the
Subphase Master independently activates L2 Slave inverters based on its own load
