Xantrex Grid-Tie/Off-Grid Inverter/Charger 4500Watts 48 Volts XW4548


Xantrex XW Hybrid Inverter/Charger designed for off-grid and back-up power applications, the XW can operate with generators and renewable energy sources to provide reliable power every time. The XW Hybrid Inverter/Charger is a true sine wave inverter/charger that incorporates a DC to AC inverter, a battery charger, and an AC auto-transfer switch. It is the foundation for battery-based residential applications up to 18 kilowatts (kW), and commercial applications up to 36 kW in a three-phase configuration.
Designed with consultation and input from industry experts, dealers, and installers, the XW sets a new standard for battery-based inverter/chargers. Integrating the best features available in the market, innovative new features by Xantrex and balance-of-systems components, the XW Hybrid Inverter/Charger’s design makes installation quicker and easier. The XW offers high efficiency and unprecedented surge capacity to maximize the owner’s return on investment. No other inverter/charger looks or performs like the XW.
