About the Xantrex Grid Tie Solar Inverter

 

 

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

 

195 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. 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 95%.

Expandable

Multiple GT Inverters may be connected in a parallel configuration for increased

 

net metering capacity or future system growth.

Communications

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

protocol

communicate with other units connected in parallel 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 with multiple wiring options to facilitate a variety of installation requirements (e.g., hard-wired, “quick-connects,” wiring box with terminals, or with AC/DC disconnect);

LCD providing easy-to-read system status and daily cumulative energy production information;

Two LED indicator lights providing status and ground fault indication;

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

WARNING: Shock hazard

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.
