  • Page 15: Introduction

    Chapter 1 contains information about the features and functions of the Xantrex Grid Tie Solar Inverter. 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.

  • Page 16: Standard Features

    Introduction 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 240 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...

  • Page 19: Installation

    Chapter 2 provides information about installing the GT Inverter. It contains information on determining a suitable location for installation, PV array requirements, and procedures for mounting the unit. Installation Options The GT Inverter may be installed as a single inverter for a single PV array of one to three PV strings (an external fuse box is required when three PV strings are connected), or in a multiple inverter configuration for multiple PV arrays.
  • Page 20 Installation Inverter failure due to improper installation will void the inverter warranty. Consider the following when determining where to install the inverter. Indoor/ Outdoor Orientation Temperature • Ground Clearance Distance Debris free 2–2 • The GT Inverter uses a Type 3R-rated enclosure (vertical mount only) that can be mounted indoors or outdoors.

  • Page 21: Pv Array Voltage And Mppt Requirements

    PV Array Voltage and MPPT Requirements WARNING: Shock hazard Whenever a PV array is exposed to sunlight, a shock hazard exists at the output wires or exposed terminals. To reduce the risk of shock during installation, cover the array with an opaque (dark) material before making any connections, and always test for voltage before touching exposed wiring or devices.
  • Page 22 Installation Guidelines for Matching PV Array Size to Xantrex Grid Tie Solar Inverter Input • Consider the expected V panel manufacturer provides a V does not exceed 600 Vdc. Panel voltage increases in cold temperatures—the panel manufacturer should be able to provide a coefficient of voltage increase per degree.

  • Page 23: Mounting The Inverter

    Mounting the Inverter Dimensions and Knockout Locations The dimensions of the inverter and the mounting bracket and some of the knockout locations on the wiring/disconnect box are shown in Figure 2-1 and Figure 2-2. Four 27 or 35 mm (1 or 1-3/8 inch) dual knockouts are provided on the back and bottom of the unit to accommodate wiring.

  • Page 24: Installing The Mounting Bracket

    Installation Installing the Mounting Bracket The mounting bracket is designed to be affixed to the vertical structure or surface to which the GT Inverter will be mounted. The GT Inverter mounting hooks attach to the flanges on the mounting bracket. If mounting more than one inverter, install each mounting bracket at least 15 cm (6 inches) apart to provide enough space for the inverters to hang side by side.

  • Page 30: Wiring Requirements

    Wiring the Inverter Wiring Requirements WARNING: Shock hazard Check for existing electrical or plumbing prior to drilling holes in the walls. The AC and DC terminal blocks in the GT Inverter accept wire sizes from #14 AWG to #6 AWG. Undersized wiring can result in significant power losses and reduction in system efficiency.

  • Page 31: Accessing The Wiring Terminals

    WARNING: Shock hazard Do not remove the wiring/disconnect box. The 600 volt DC/AC disconnect in the wiring box meets NEC Article 690. It is a non-serviceable component and shall remain in place. Removal can expose energized conductors. Use caution when working around sources of DC power. Although the DC/AC disconnect switch disconnects the inverter from DC power, hazardous voltages from paralleled PV strings will still be present upstream of the switch and inside the wiring box.

  • Page 35: Dc Wiring For Multiple Inverters

    DC Wiring for Multiple Inverters For installations with multiple GT Inverters, separate solar arrays are required for each unit. The output of each GT Inverter feeds a separate dual-pole 30-amp circuit breaker (L1 and L2) in the main utility service panel. For such installations, complete the wiring and perform the commissioning procedure for each inverter one at a time.

  • Page 36: Connecting The Ac Wiring

    Wiring the Inverter Connecting the AC Wiring WARNING: Shock hazard Before wiring the GT Inverter, ensure the main breaker in the primary utility breaker box is switched OFF. Switch this breaker ON only after all wiring is completed as instructed in the procedures.

  • Page 37: Dc And Ac Wiring For Multiple Inverters

    DC and AC Wiring for Multiple Inverters DC and AC wiring for multiple inverters is illustrated in Figure 3-10. If there will be more than one PV array, label the positive and negative wire pairs appropriately (for example: PV1 POS, PV1 NEG, PV1 GND, PV2 POS, etc.). If required by the AHJ, a DC grounding conductor may be connected to each inverter’s ground bar.
