The Schneider Conext XW Series hybrid inverter/charger has an innovative, integrated design that minimizes external balance-of-system components allowing for quick and easy installation as either a grid-tie battery-backup system or a fully off-grid power system. The XW offers split-phase 120/240VAC output from a single inverter. Up to 4 inverters can be paralleled for up to 24kW of total output in a 120/240V split-phase system, or operate in a 208VAC 3-phase configuration with up to 2 inverters per phase (6 inverters total) for up to 36kW of power. Models are also available for 230V or 400VAC three-phase at 50Hz for overseas operation. Charge controllers, such as the MPPT06-150 or the MPPT80-600, are required for use with any PV array (see Charge Controllers).
A digital controller regulates the output voltage and maintains the voltage level during a surge load. An efficient, power-factor-corrected, high-current multi-stage battery charging minimizes recharge time. Dual AC inputs enable AC generator input as well as grid interaction. An optional automatic generator start (AGS) unit is also available. A configurable auxiliary relay output of 250mA at 12VDC included in each inverter.
The inverter display panel shows status at a glance. LEDs indicate AC-in status, faults/warnings, equalize mode, and battery state of charge. Three-character LED indicates output power or charge current. A battery temperature sensor is included with each inverter, but only one is needed per system.
The Power Distribution Panel includes a conduit box and all AC/DC disconnects and wiring to support one inverter. The distribution panel has wiring space and enough knockouts to add up to three inverters and/or four charge controllers. Each charge controller requires an input breaker and output breaker listed in the table below. Field-reversible door with magnetic catch makes access to wiring easy.
The XW Connection Kit contains everything needed to add a second inverter. For a third inverter, use one Connection Kit plus a pair of 5-foot 4/0 inverter cables, with lugs on each end. An external transfer switch will be required if the inverter bypass function is desired. For four inverters, use two Power Distribution Panels and two Connection Kits.
Use the XW conduit box to retrofit XW inverters into existing systems which already have AC/DC disconnects.
The XW System Control Panel plugs into the Xanbus network and provides a central user interface to configure and monitor all components in the system. One is required per XW system to change inverter programming. The Communications Gateway in Charge Controller section can be used to connect the XW to a PC.
5-year warranty. CSA Listed to UL 1741 for the U.S. and Canada. Dimensions of the inverter are 16 x 23 x 9 inches. The inverter is field-serviceable without needing to remove it from the wall.
