Installation2–30 975-0012-01-02 Rev ASeries Stacking (120 Vac/60 Hz Models only)This COM port allows two DR Inverters (120 Vac/60 Hz models only) to be usedin the same system in a “SERIES” configuration to operate 240 Vac loads. Seriesstacking can also be used to connect to 240 Vac only power systems providingboth 120 and 240 Vac outputs. A series stacking interface cable (DRI) is requiredto connect the series stacking port of the inverters.In this mode, one of the inverters will function as the “primary” and the otherinverter becomes the “secondary.” The first unit switched ON becomes theprimary and ensures the secondary’s output is 180 degrees out of phase for240 Vac operation. Both units can charge the batteries or provide battery backuppower during a utility outage.The following illustrations provide a general overview of AC configurations usingstacked inverters. Detailed wiring and operating instructions are provided with theDRI interface kit available from Xantrex Technology Inc.The following diagrams illustrate the AC Wiring for a basic On-Grid and Off-Gridapplication.
