Three-Phase Configuration - Conext XW+ 6848 NA Owner's Manual

Three-Phase Configuration

975-0240-01-01
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.
30
KVA GRID SELL LIMITATION
The Conext XW+ has non-adjustable setpoints for response to abnormal grid
frequency and voltage (see "Response to Abnormal Grid Conditions" on
page A–4). Do not aggregate Conext XW+ units on a common point of
connection to the grid in excess of 30 kVA (per Std IEEE1547: 2003). Consult
with a local utility inspector before enabling the Sell feature on the Conext
XW+.
Failure to follow these instructions can result in equipment damage.
When installed in a three-phase system, the Conext XW+ requires a designated
master unit on each phase. If there is not a master unit on each phase, a system-
wide fault (F66) is asserted. Before setting up a three-phase system, confirm that
the Conext XW+ units have been installed and wired for three-phase. See the
Conext XW+ Inverter/Charger Installation Guide for further information.
The Conext XW+ is capable of supporting three-phase systems and supports
different configurations for grid-tie and off-grid applications. The Conext XW+ will
support either three units or six units in a three-phase grouping when deployed
as a grid-tie backup system. If energy is to be sold to the grid, the system must
be adjusted to so that it does not exceed 30 kW. The power adjustment on each
phase must be made at the time of commissioning and under supervision of a
utility representative. Off-grid deployment of six or more Conext XW+ units in a
single three-phase grouping is not supported.
For off-grid applications, the Conext XW+ is deployed in clusters of three units
(one per phase) for three-phase off-grid systems. Up to three clusters can
support off-grid using an external AC contactor system for managing the AC bus
line between sources of AC and consumption loads. For the installation, setup
and commissioning of multi-cluster systems, refer to the Off-Grid Systems Guide
for Conext XW+ available at http://solar.schneider-electric.com.
