Use the MATE to establish the order or hierarchy of all the system FXs by designating each one of the
following (in order as they appear on the MATE):
• Master (series stacking or 3-phase stacking)
• Classic Slave (series stacking)
• 3p Classic B (3-phase stacking)
• 3p Classic C (3-phase stacking)
Other options will be displayed, but they are not supported on this FX model.
master
• This is the default ranking of every FX.
• One Master FX is established for every multiple FX system. It applies to one-phase, two-phase or
three-phase systems.
• Each Grid-Interactive FX can be a Master as long as each is connected to a separate battery and a
separate AC output leg (both HOT and NEUTRAL).
• If one Grid-Interactive FX is designated as the system’s only Master, it is always considered to be the
Leg 1 phase.
Classic Slave
• Classic Slave is the designation of the second FX in a two-inverter, split-phase system that produces
240 VAC.
• This FX is plugged into Port 02 of the HUB and is considered to be the L2 phase.
3p Classic B
• In 3-phase stacking, the unit which is plugged into HUB Port 02 (phase B) is designated as 3p Classic B.
3p Classic C
• In 3-phase stacking, the unit which is plugged into HUB Port 03 (phase C) is designated as 3p Classic C.
