Three-Phase Stack (Subphase Master)

Up to 9 inverters (ports 1 to 9); 1 other device (port 10); MATE3 only

Master inverter (required on port 1) and up to two Slave inverters (ports 3 & 3) use Phase A output AC bus

Subphase Master inverter (required on port 4) and up to two Slaves (ports 5 & 6) use Phase B output AC bus

Subphase Master inverter (required on port 4) and up to two Slaves (ports 8 & 9) use Phase C output AC bus

Phase A, B, and C Slave inverters should be equal in number; Slave selection screen may display

Slave but

could display

OB Slave L1 depending on model

Master and Subphase Masters are always active; each type of Master regulates output based on its own load

Slave inverters remain in Power Save mode; the Master activates Phase A Slave inverters based on its load,
while the Subphase Masters

independently activate Phase B or C Slave inverters based on their own loads

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
