Configuring System for Stacked Operation

Verify all DC and AC connections. Check Xanbus network connections and ensure that terminators are installed at devices at each end of the network. The simplest system includes a Xanbus SCP, the two Freedom SW 230V inverter/chargers to be stacked and two Xanbus terminators.

For both units to operate in stacked configurations, a Master and Slave have to be assigned. The default out-of-box configuration for all Freedom SW 230V inverter/chargers is Master which causes a conflict the first time the system is powered up. The installer will need to change configuration on one of the inverter/chargers to Slave mode.

To configure the system for stacking:

1.Apply DC power to both inverter/chargers.

Power up order has no impact. Because there are now two Master units in the system, the SCP will display an F66 fault, a “system configuration fault”.

2.From the SCP System Status screen, press Enter. The Select Device screen appears.

3.Select the inverter to configure as a Slave unit from the list, then press Enter.

4.Bring up the Advanced Settings screen by pressing Enter, Up, and Down arrow buttons all together.

The only situation in which the Slave may shut down the Master

inverter is during fault conditions such as high or low battery voltage, overcurrent, or over-temperature conditions. Both inverters will auto reset after a fault condition has been cleared. The exception is that an overcurrent condition will generate a shutdown for both inverters that will require a manual restart of the system.
