Introduction

Basic Features
The XW Hybrid Inverter/Charger is a true sine wave inverter/charger that can be
used for residential and commercial applications: stand-alone, grid-backup, and
grid-tie with battery energy storage. Capable of being grid-interactive or grid-
independent, the XW Inverter/Charger will operate with generators and renewable
energy sources to provide full-time or backup power.
Other XW Inverter/Charger features include:
• High efficiency true sine wave output
• Building block power levels—Up to three inverters can be installed together
in a 230 volt, single-phase, two-wire configuration to produce up to 18
kilowatts. Multiple units can also be connected to create a three-phase system.
At least one inverter per phase is required, and up to two inverters can be
connected in parallel on each phase.
• Surge capacity to start difficult loads like well pumps, refrigerators or A/C
compressors
• Power factor-corrected (PFC) input minimizes AC input current required for
charging, increasing AC pass-through capacity
• High DC output current and multi-stage charger minimize charging time
• Optional XW Automatic Generator Start allows operation with a wide range
of generators, supported through a dedicated generator input
• Supports multi-mode grid-tie operation
• Integrated transfer switch
• Temperature-controlled, variable-speed internal cooling fan. The fan turns on
when the internal temperature reaches 45 °C and reaches maximum speed at
70 °C. The fan turns off when the internal temperature falls to 40 °C.
• Housing design promotes vertical air flow through the inverter. This natural
“chimney effect” provides convection cooling at lower power levels, and
reduces fan run time.
• Designed for reliability and field serviceability.
System component
The XW Inverter/Charger uses Xanbus™, a network communications protocol
developed by Xantrex, to communicate its settings and activity to other Xanbus-
enabled devices. You can configure and monitor the XW Inverter/Charger and
every Xanbus-enabled device in the system using an XW System Control Panel
(part number 865-1050).
