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

(MPPT)

array. Xantrex MPPT learns your array’s specific characteristics, maximizing its

 

output at all times.

High efficiency

The high-frequency, solid-state design of the GT Inverter is extremely efficient—

 

up to 96.2%.

Expandable

Multiple GT Inverters may be networked together for increased net metering

 

capacity or future system growth. The GT Inverter GT5.0 has adjustable voltage

 

and frequency disconnect settings and can be aggregated above 30 kW on a single

 

point-of-common-coupling (PCC). See “Adjustable Voltage, Frequency and

 

Reconnection Settings” on page A–3.

Communications

The GT Inverter uses the Xanbus® communications protocol, enabling it to

protocol

communicate with multiple units connected within the system. For more

 

information, see “Xanbus Network Technology” on page 3–12.

Standard Features

The GT Inverter has the following standard features:

•Sealed inverter section protecting power electronic components;

•Liquid Crystal Display (LCD) providing easy-to-read system status and daily cumulative energy production information;

•Two LED indicator lights providing status and ground fault indication;

•Wiring/disconnect box providing protection for all AC and DC connections and eliminating exposed “live” wiring if the inverter is removed.

The wiring/disconnect box has been designed to be physically mated to the electronics section of the GT Inverter at the factory, but remains in place as a non-serviceable item in the event that the inverter electronics section is ever required to be removed. The inverter and wiring/disconnect box together form an NEMA 3R enclosure to allow outdoor installation.

WARNING: Shock hazard

The 600 volt DC/AC disconnect in the wiring/disconnect box meets NEC Article 690. It is a non-serviceable component and shall remain in place. Separating the inverter and wiring/disconnect box, or removing the wiring/disconnect box cover can expose energized conductors. PV input circuits in the wiring box ahead of the switch remain energized even when the switch is in the “off” position—hazardous voltage will still be present on the DC input (PV) terminals under the clear plastic insulation barrier inside the wiring/disconnect box.
