Introduction

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 1-1for 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.
