Connections Menu
The Connections menu contains additional settings to allow the Conext XW+ to
function as part of a multi-unit networked system.
Setting the connections for a Xanbus-enabled device provides a way of
identifying non-network associations for Xanbus-enabled devices (see Figure 3-
11) and enhancing networked power system management. When connections
are set, devices of different types become associated and can share sources,
e.g. a common DC input source, or a common grid/generator source.
In multi-unit networked systems, multiple inverter/chargers can be stacked to
produce increased charge current. To achieve this functionality, the devices must
be configured to the same DC connection, such as House Battery Bank 1. The
units will collaborate on battery charging by communicating with other units on
this shared DC connection.
