Xantrex GT Series

Xantrex GT Series 3-Phase Commercial/Industrial Inverters

Schneider Electric's Xantrex GT three-phase inverters are available in sizes from 30 kW to 250 kW. The compact, 165-pound, 30 kW inverter is in a wall-mounted aluminum enclosure and requires a symmetrical array input (split array +/- 180-430VDC). The 100 kW and 250 kW inverters have pad-mounted epoxy-coated steel enclosures with integrated transformers and disconnects. These inverters can be configured for positive ground, require zero clearance on back and sides and can fit through standard doors.

Warranties are available for up to 10 years of coverage, service contracts and uptime guarantees for up to 20 years. All inverters are listed to UL 1741 and IEEE 1547 and are listed with the California Energy Commission.

Xantrex GT30 Solar Inverter

The Xantrex GT30 solar grid-tie inverter features a transformerless bipolar design with high conversion efficiency and a wide PV maximum power tracking voltage range. Transformerless design increases efficiency and reduces the size, weight and noise of the inverter. The GT30 is significantly smaller (22" W x 48" H x 13" D) and lighter (165 lb) than other 30 kW inverters allowing greater installation flexibility, and greatly reducing structural loading in rooftop installations.

The Xantrex GT30 bipolar design requires a symmetrical array input (split array +/- 180-430VDC) with two identical photovoltaic subarrays, PV1 and PV2, of opposite polarities with respect to ground. The negative terminal of monopole PV1 and the positive terminal of monopole PV2 will be automatically grounded inside the Xantrex GT30. Both subarrays need PV modules to be of the same type, number, orientation and electrical configuration. Bipolar design, coupled with internal inverter ground points, eliminate the need for double-insulated DC conductors.

The GT30's outdoor rated, aluminum, corrosion resistant cabinet, low weight, and included wall mount bracket allow for flexible installation. Operator interface controls are located on the front face of the inverter enclosure, and include a 4-line LCD display, an AC disconnect switch handle, and a PV disconnect switch handle. AC and DC switchgear are included to reduce installation expense and visual clutter. Multiple inverters are easily paralleled for 60 kW, 90 kW, 120 kW and larger for modular growth applications for larger PV plants. Nominal output voltage of the GT30 is 208VAC, but autotransformers are available from Schneider Electric for connection of 1, 2, or 3 inverters to a 480VAC service.

The Xantrex GT30 provides an option for communicating system status and data logging with a PC through the RS-485/modbus connection, or via an RS-232 connection and a modem, using the PV View Graphic User Interface (GUI) software.

Fully compliant with the NEC and UL Listed to UL 1741 for the U.S. and Canada; 96% CEC efficiency; Standard 5-year warranty with 5-year extension available.
