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).
