Safety Information
1. Before using the inverter, read all instructions and cautionary
markings on the unit, the batteries, and all appropriate sections of
this manual.
2. Use of accessories not recommended or sold by the manufacturer may result
in a risk of fire, electric shock, or injury to persons.
3. The inverter is designed to be permanently connected to your AC and DC
electrical systems. The manufacturer recommends that all wiring be done by
a certified technician or electrician to ensure adherence to the local and
national electrical codes applicable in your jurisdiction.
4. To avoid a risk of fire and electric shock, make sure that existing wiring is in
good condition and that wire is not undersized. Do not operate the inverter
with damaged or substandard wiring.
5. Do not operate the inverter if it has been damaged in any way.
6. This unit does not have any user-serviceable parts. Do not disassemble the
inverter except where noted for connecting wiring and cabling. See your
warranty for instructions on obtaining service. Attempting to service the unit
yourself may result in a risk of electrical shock or fire. Internal capacitors
remain charged after all power is disconnected.
7. To reduce the risk of electrical shock, disconnect both AC and DC power
from the inverter before attempting any maintenance or cleaning or working
on any components connected to the inverter. Putting the unit in Standby
mode will not reduce this risk.
8. The inverter must be provided with an equipment-grounding conductor
connected to the AC input ground.
9. Do not expose this unit to rain, snow, or liquids of any type. This product is
designed for indoor use only. Damp environments will significantly shorten
the life of this product and corrosion caused by dampness will not be
covered by the product warranty.
10. To reduce the chance of short-circuits, always use insulated tools when
installing or working with this equipment.

Features
The Conext XW+ is a modular building block sine-wave inverter/charger that can
be used for residential and commercial battery based off-grid, grid backup, and
grid interactive applications.
The Conext XW+ is a self-contained DC to AC inverter, battery charger, and
integrated AC transfer switch. It is configurable in a hybrid system to operate with
generators and renewable energy sources. These configurations are capable of
extending battery based off-grid/backup autonomy.
Performance Highlights
• Excellent load starting with high 30-minute and 5-second power.
• Off-grid AC Coupling with PV inverters using frequency power curtailment
method.
• Operation in hot environments up to 70°C.
• Conversion of DC energy to AC energy for export to the utility grid.
• Power factor corrected charging minimizes AC current required for charging.
• True sine wave output.
Distinguishing Features
• Grid-interactive feature set enables time management and prioritization of
energy sources and power conversion to support advanced modes of
operation such as load shifting, self consumption and peak load shaving.
• Dual AC input connections with 60 A automatic transfer switch integrates
both utility grid and generator.
• Generator Support functionality assists small generators with heavy loads.
• Auxiliary port assist with relay switching of external devices such as battery
room fans, diversion loads and generators.
• Configurable battery parameters for customized battery charging.
• Field serviceable boards and components.
Xanbus™ Network Communications Protocol
The Conext XW+ uses Xanbus™, a network communications protocol developed
by Schneider to communicate with other Xanbus-enabled devices. You can
configure and monitor the Conext XW+ and other Xanbus-enabled devices in the
system using the Conext System Control Panel (part number 865-1050-01) or
Conext ComBox (part number 865-1058).

Operation
Bidirectional Theory of Operation
The Conext XW+ is a grid forming device consisting of a bidirectional inverter/
charger. It is capable of inverting DC power into AC power and controlling the
voltage and frequency of its inverter output. It will power external loads attached
to AC OUT (See Figure 1-2, “Inverting of DC to AC Connected to AC OUT” on
page 1–4).
The Conext XW+ is also capable of charging external batteries by converting AC
power into DC power (See Figure 1-3, “Charging External Batteries and
Supplying AC Out with AC Passthrough from AC1 Grid ” on page 1–5). The
Conext XW+ accepts AC power through connection AC2 for charging batteries,
usually from a generator (See Figure 1-4, “Charging External Batteries and
Supplying AC Out with AC Passthrough from AC2 Generator” on page 1–5).
The Conext XW+ will convert externally sourced DC power into AC power for
export to the utility grid attached to its AC1 connection (See Figure 1-5,
“Converting Excess Available DC power for Export to Utility Grid (AC1) and AC
Out” on page 1–6).
The Conext XW+ has an internal automatic transfer switch (K1, K2) which allows
either AC1 or AC2 to be connected to the inverter input, but not both at the same
time (See Figure 1-1, “Connection Points and Major Power Conversion
Components of Conext XW+ ” on page 1–4). This allows shared AC energy
during charging or to directly passthrough from AC1, or AC2, to AC Out.

Introduction
1–4 975-0240-01-01
Through firmware control over power conversion and the management of K1 and
K2, Conext XW+ can facilitate advanced interaction with the utility grid to
optimize the utilization of renewable and non-renewable energy sources.
Because the Conext XW+ is a device capable of forming an AC grid signal (AC
voltage and frequency) it is also ideal for use off-grid.
The red arrows in the diagrams below represent the direction of power flow in the
respective modes of operation. These modes and other special functions will be
explained throughout this manual.
