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. See Figure 1-1 for a
simple diagram of a typical installation.
In order to operate, the GT Inverter must have grid power available and connected.
It will not provide backup power if the AC grid fails.
