Schneider Electric Conext XW Inverters
The Conext XW Series hybrid inverter/chargers have 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 120/240 VAC output from a single inverter. Up to four inverters can be paralleled for up to 27 kW of total output in a 120/240 VAC split-phase system. Charge controllers, such as the Schneider Electric XW-MPPT60-150 or the XW-MPPT80-600, are required for use with any PV array (see Charge Controllers).
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 with an output of 250 mA at 12 VDC is included in each inverter. A battery-temperature sensor is included with each inverter, but only one is needed per system. The inverter is field-serviceable on the wall.
The Conext XW Pro 6.8kW hybrid inverter/charger is an updated version of the XW+ line. The XW Pro has the ability to adapt to the new utility requirement for grid tied inverters. The XW Pro comes with a 5-year warranty is listed to UL1741-SA standard and can be installed and connected to utilities in areas where that is required, such as California Rule 21. Dimensions of the inverter are 23"H x 16"W x 9"D, 169 lbs.
NOTE: The XW Pro should be used with the Conext Gateway instead of the Combox for LAN and internet connections.
The Conext XW+ inverters can be converted to 120 VAC only and three inverters can be configured into a 120/208 VAC three-phase system. The XW+ comes with a 5-year warranty and is listed to UL 1741 for the U.S.A. and Canada. These inverters are NOT currently listed to the new UL1741-SA standard and cannot be installed connected to utilities in areas where that is required. Dimensions of the inverter are 23"H x 16"W x 9"D.
A Conext System Control Panel should be used with an XW system for programming and control of the system.
