  • Page 22: About The Xantrex Grid Tie Solar Inverter

    Introduction About the Xantrex Grid Tie Solar Inverter The Xantrex Grid Tie Solar Inverter (GT Inverter) is designed to convert solar electric (photovoltaic or PV) power into utility-grade electricity that can be used by the home or sold to the local power company. Installing the GT Inverter consists of mounting it to the wall and connecting the DC input to a PV array and the AC output to the utility.

  • Page 23: Standard Features

    PV compatibility The GT Inverter is designed to take advantage of solar modules configured as high voltage PV string arrays—single crystalline, poly crystalline, or thin film—with a 195 to 550 Vdc input voltage Maximum Power Point range. Maximum Power The GT Inverter uses Xantrex proprietary Maximum Power Point Tracking Point Tracking (MPPT) technology to harvest the maximum amount of energy from the solar (MPPT)
