Introduction

Chapter 1, “Introduction” provides information about the features and
functions of the PV100S 100 kW Grid-Tied Photovoltaic Inverter.

Introduction

Description of the PV100S

The PV100S 100 kW Grid-Tied Photovoltaic Inverter is a UL 1741 listed,
utility interactive, three-phase power conversion system for grid-connected
photovoltaic arrays with a power rating of 100 kW. Designed to be easy to install
and operate, the PV100S automates start-up, shutdown, and fault detection
scenarios. With user-definable power tracking that matches the inverter to the
PVarray and adjustable delay periods, users are able to customize start up and
shut down sequences. Multiple PV100S inverters are easily paralleled for larger
power installations.

The PV100S power conversion system consists of a pulse-width modulated
(PWM) inverter, switch gear for isolation and protection of the connected AC and
DC power sources, and a high efficiency custom Wye:Wye isolation transformer.
Housed in a rugged NEMA 3R rated, galvanized steel enclosure, the PV100S
incorporates sophisticated Intellimod
(IGBTs) as the main power switching devices. An advanced, field-proven,
Maximum Peak Power Tracker (MPPT) integrated within the PV100S control
firmware ensures the optimum power throughput for harvesting energy from the
photovoltaic array.

The advanced design of the PV100S includes an EMI output filter and the main
AC contactor located electrically on the utility side of the isolation transformer.
The location of the main AC contactor, and the ability to de-energize the isolation
transformer during times of non-operation, greatly reduces the night-time tare
losses consumed by an idle isolation transformer. An integrated soft-start circuit
precludes nuisance utility-tie circuit breaker trips as the result of isolation
transformer inrush current.

(IPM) Insulated Gate Bipolar Transistors

Additionally, the PV100S integrated controller contains self-protection features
including over and under voltage and frequency safeguards. An integral
anti-island protection scheme prevents the inverter from feeding power to the grid
in the event of a utility outage. The PV100S includes a local user interface
comprised of an O
user-friendly, Graphic User Interface (GUI) provides a remote interface for
operator interrogation of PV100S system status, control, metering/data logging
and protective functions within the PV100S. The status, control, and lo gging
features are also supported by the choice of three communication mediums,
allowing the information to be accessed or commanded remotely.

The PV100S comes in two modules comprised of six enclosures to house the
electronics described above. The first module includes the Main Inverter
Enclosure, Inductor Enclosure, DC Interface Enclosure, and Communication
Enclosure. The second module includes the Transformer Enclosure and AC
Interface Enclosure. These components are identified in Figure 1-1 on page 1–3.
Figure 1-1 also shows the dimensions and locations of the various enclosures that
comprise the PV100S.

See “Layout Options” on page 2–6 for information on configuration options.

System Ground Requirements

This product is intended to be installed as part of a permanently grounded
electrical system per the National Electrical Code ANSI/NFPA 70. A copper
ground rod must be installed within three feet of the PV100S enclosures and
connected to the unit as described in “System Grounding” on page 3–12. The
single-point ground for the system is to be made at the AC ground bus bar (TB2)
in the AC Interface Enclosure.

System Neutral Requirements

The PV100S is designed to be installed as a 4-wire system. As required by the
UL 1741 listing, a neutral conductor from the utility-interconnect must be
terminated at TB6 within the AC Interface Enclosure to ensure that the AC
voltage sensing circuit can perform an individual phase voltage (line-to-neutral)
measurement. The function of the neutral connection is to provide a point of
reference for measurement purposes that is essentially at ground potential. No
power will flow through the neutral conductor.

Utility Side Isolation Transformer Requirements

The PV100S is supplied with a high-efficiency custom Wye:Wye isolation
transformer as part of the AC Interface/Transformer assembly. The utility side
windings of the isolation transformer are configured Wye and must match the
voltage at the utility inter-tie. The PV100S is a balanced, three-phase,
current-sourcing inverter and only operates with the presence of a stable utility
voltage. The transformer is also supplied with a neutral connection on the utility
interconnect. Connection of this utility-side neutral does not affect the operation
of the inverter; however, connection of the neutral on the inverter -side does af fect
the operation and must be left floating or disconnected. Single-phase, grounded
loads, which may be present between the transformer and utility, will maintain
their existing ground reference at the utility distribution transformer.

System Specifications

CAUTION: Equipment Damage

If the Isolation Transformer (T6-X0) neutral terminal is tied to ground, it will cause
irreparable damage to the PV100S. Check local regulations for their requirements
regarding the connection of the neutral.

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 PV100S 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.
