Line or Phase Inverter Mode
Line-2 or Phase-B 3Ph L2 Master
3Ph L2 Slave
Line-3 or Phase-C 3Ph L3 Master
3Ph L3 Slave
a.Each phase can support one master unit and one slave unit.
b.The L1 Master is also the master Conext XW+ for the entire system. The system master
broadcasts phase synchronizing pulses through its sync port, and each phase master con-
trols the slave units on its respective phase.
c.The slave unit in each phase is optional.
ADVANCED CONFIGURATION HAZARD
Advanced menu settings should be used by qualified personnel only.
Three phase operation should be configured by qualified personnel only.
Consult with the local utility before enabling Conext XW+ sell mode or grid
support functions.
Do not change these settings unless you are under the supervision and
direction of qualified personnel.
Failure to follow these instructions can result in death or serious injury.
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.
Note: When configuring clusters of three Conext XW+ units (or a grouping of up
to six in a grid-tie application), each cluster's DC connections must be set to the
same battery bank. If one of the units is set with a different DC connection, a
system configuration fault (F66) occurs.
