1 Introduction Chapter 1, “Introduction” provides information about the features and functions of the Xantrex GT100 E 100 kW Grid-Tied Photovoltaic Inverter. This manual is for use by qualified personnel only.
Introduction Description of the Xantrex GT100 E The Schneider Electric Model Xantrex GT100 E 100 kW Grid-Tied Photovoltaic Inverter is a single enclosure, three-phase power conversion system for gridconnected photovoltaic arrays with a rating of 100 kW. The Xantrex GT100 E inverter incorporates the innovative switching technology utilizing state-of-the-art IPMs (Intelligent Power Module), to convert the photovoltaic array's DC power to the utility's three-phase AC power.
Operator Interface Controls Operator Interface Controls WARNING: Shock hazard Turning the ON/OFF switch to the OFF position does not remove all hazardous voltages from inside the inverter. Before attempting to service the Xantrex GT100 E, follow the de-energize Lockout and Tag procedure on page xi.
Introduction ON/OFF Switch WARNING: Shock hazard Turning the ON/OFF switch to the OFF position does not remove all hazardous voltages from inside the inverter. Before attempting to service the Xantrex GT100 E, follow the de-energize Lockout and Tag procedure on page xi. The Xantrex GT100 E incorporates a maintained position ON/OFF switch located on the front door of the inverter enclosure. Under normal conditions, the ON/OFF switch is in the ON position.
Operator Interface Controls Emergency Stop (E-STOP) The Xantrex GT100 E incorporates a maintained position E-STOP pushbutton located on the inverter enclosure. Under normal conditions, the E-STOP pushbutton is in the CLOSED (extended) position. Pushing the pushbutton to the OPEN (depressed) position will initiate an immediate controlled shutdown of the Xantrex GT100 E and open both the main AC and DC contactors within the unit.
Introduction AC Disconnect Switch WARNING: Shock hazard Disengaging the inverter enclosure door interlock switch does not remove all hazardous voltages from inside the inverter. Before attempting to service the Xantrex GT100 E, follow the de-energize Lockout and Tag procedure on page xi. The AC disconnect switch is the primary disconnect for the inverter. The inverter’s doors cannot be opened until the AC disconnect switch is in the OFF position.
Operator Interface Controls Front Panel User Interface The Xantrex GT100 E has a front panel user interface which is comprised of a 4-line display screen for reporting basic system status and all fault conditions plus a keypad for configuration. The keypad is comprised of 20 touch-sensitive keys that provide a means to navigate through the menus and alter userchangeable settings.
Introduction Communication Features and Methods The Xantrex GT100 E provides two types of information to the user: • system status and/or fault information, and • data logging information. System status and fault information can be accessed using the user interface keypad and display or a personal computer using the PV View GUI (Graphic User Interface) software. Data logging requires the use of a PC using the PV View.
Communication Features and Methods Data Logging The inverter stores data values and software metrics for debugging. These values are stored within the CCU2 controller board in non-volatile memory. Data logging requires the use of a PC connection using the PV View.
Introduction Optional Equipment The following options are available for purchase for use with the Xantrex GT100 E to enhance its communications capability. The additional Xantrex GT100 E options can be field installed. Contact a Schneider Electric distributor for further information on installation options. External Analog Input Requirements The Xantrex GT100 E has an option for measuring external devices through its 4 analog input lines.
2 Planning Chapter 2, “Planning” provides information to help plan the installation of the Xantrex GT100 E 100 kW Grid-Tied Photovoltaic Inverter. This manual is for use by qualified personnel only.
Planning Overview of Xantrex GT100 E Installation WARNING: Shock hazard Installations of this equipment should only be performed by qualified technicians. Installers must meet all local and state code requirements for licensing and training for the installation of Electrical Power Systems with AC and DC voltage to 650 volts.
Environmental Requirements Environmental Requirements The following environmental conditions must be established and maintained to ensure the safe and efficient operation and servicing of the Xantrex GT100 E. • Maintain a minimum clearance of 31 cm (12 in,) plus local safety requirements in front and back of the enclosure for air intake, fan cooling, maintenance and serviceability. • External cabling enters the Xantrex GT100 E from the bottom.
Planning Utility Side Isolation Transformer Requirements WARNING: Lethal voltage Grounding the neutral of a Wye-wound transformer may create an “open delta” condition, depending on the utility configuration. This condition may keep the Xantrex GT100 E from detecting a loss of phase condition on the utility system, which may allow potentially lethal voltage to be present on the open-phase wiring.
