Description of the Xantrex inverter
Designed to be easy to install and operate, the Xantrex GT500 E 500 kW and
Xantrex GT630 E 630 kW Grid-Tied Photovoltaic Inverters automate start-up,
shutdown, and fault detection scenarios. With user-settable power tracking that
matches the inverter to the array and adjustable delay periods, users are able to
customize start up and shut down sequences. Multiple Xantrex GT500 E or
Xantrex GT630 E inverters are easily paralleled for larger power installations.
The Xantrex inverter power conversion system consists of a pulse-width
modulated (PWM) inverter, and switch gear for isolation and protection of the
connected AC and DC power sources. Housed in a rugged IP20 rated,
galvanized steel enclosure, the Xantrex inverter incorporates sophisticated
Intellimod
(IPM) insulated gate bipolar transistors (IGBTs) as the main power
switching devices. An advanced, field-proven, maximum peak power tracker
(MPPT) integrated within the Xantrex inverter control firmware ensures the
optimum power throughput for harvesting energy from the photovoltaic array.
Protection
Features
The advanced design of the Xantrex inverter includes an EMI output filter and the
main AC contactor located electrically on the inverter side of the isolation
transformer. Additionally, the Xantrex inverter integrated controller contains self-
protection features including over and under voltage and frequency safeguards.
An integral anti-island protection scheme (Xantrex GT500 E & Xantrex GT630 E
base units only) prevents the inverter from feeding power to the grid in the event
of a utility outage.
User Interface
The Xantrex inverter includes a local user interface with a
3
(stand-by/power-on)
switch (called
ON
/
OFF
on older models), a keypad, and a 4-line, 80 character
display. An available user-friendly Graphic User Interface (GUI) can provide an
interface for the user to query Xantrex inverter system status, control, metering/
data logging and protective functions. These features can be accessed remotely
using an optional communication kit.
Physical
Characteristics
The Xantrex inverter comes in a set of three enclosures to house the Electronics
described above. The left 1-door section is the AC interface enclosure (+H0).
The center 2-door section is the main inverter enclosure (+H1). The right 1-door
section is the DC interface enclosure (+H2). The three enclosures are
constructed and delivered as one complete assembly. These components are
identified in Figure 1-1 on page 1–3 and the dimensions are identified in Figure
A-1 on page A–6.
Grid Interactive
Options
The Xantrex GT500 E GI or Xantrex GT630 E GI has all of the features of the
Xantrex GT500 E or Xantrex GT630 E base unit (respectively), with the addition of
either VAR control or VAR control and low voltage ride through together. The low-
voltage ride-through capability allows the inverter to continue operation during
dips in the AC voltage and power-factor compensation, by using array, not line
voltage to compensate for extra capacitance or inductance on the grid based on
the user-settable parameters. To facilitate these features, the ride-through option
does not provide anti-islanding protection. The VAR control provides reactive
power control for full power across the power factor range.
1000 V Input
Option
The Xantrex GT630 E GI 1K enables the Xantrex GT630 E to accept input
voltages up to 1000 Vdc.
