Freedom SW 230V Installation Guide
Stacking Features
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.
5. Select
Advanced Settings
and press
Enter
. The
Advanced Settings screen appears.
6. Scroll down to select
Stacking
.
At this point all devices in the system will be
automatically placed in standby mode. All three LEDs on
the inverter to be configured will start flashing.
