About the Sun Tie XR
The Xantrex Sun Tie XR grid-connect solar inverter is designed to
convert a home or business into a “green” power generating station. The
Sun Tie XR converts solar electric (photovoltaic, or PV) power into
utility-grade electricity that can be used by the home or sold to the power
company. Installing the Sun Tie XR consists of mounting it to the wall
and connecting a DC source (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 Sun Tie XR must have grid power available and connected. It
will not provide backup power.
