Stacking (Subphase Master)
 Up to 8 inverters (ports 1 to 4, 7 to 10); balancing transformer is not used
 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 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
 Ports 5 and 6 not used for inverters; these and any unused slave ports can host other devices
