Multi-Unit Config Menu
The Multi-Unit Config menu configures the XW Inverter/Charger to operate as a
part of a multi-unit installation.
When installing a multi-unit system, each setting on the Multi-Unit Config menu
(except for “Dev Name”) must be configured for each XW Inverter/Charger in the
system. The Multi-Unit Config settings should be configured in the following
order:
• Dev Number
• Inverter Mode
• Connections.
Setting the Device Name
The “Dev Name” setting allows you to customize the name of the XW Inverter/
Charger as it is displayed on other screens and menus.
The characters available are:
• A to Z
• a to z
• 0 to 9
• space.
Important:
Accessing this menu automatically places the XW Inverter/Charger in
Standby mode. When entering the Multi-Unit Config menu, the unit also identifies itself
by flashing all front panel lights. After exiting the Multi-Unit Config menu, the XW
Inverter/Charger returns to Operating mode and the front panel lights stop flashing.
