Grid Tie: Using the Xantrex Grid Tie Interface (GTI), the SW converts energy from multiple renewable energy sources, such as solar, wind, and microhydro, into AC power, selling power you don't use back to the utility. Software/hardware revision 4.2 or higher is required to connect the SW4024, SW4048, or SW5548 to the GTI.
