All XW Hybrid Inverter/Chargers are true sine wave inverter/chargers that can be used for both residential and commercial applications; stand-alone, grid-backup, and grid-tie with battery energy storage. The Xantrex XW inverters are the most efficient (~95%) that we know of for grid-interactive, where you are selling back excess power from a battery based system.
Capable of being grid-interactive or grid-independent, the XW Series will operate with generators and renewable energy sources to provide full-time or backup power.
