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.

The Xantrex Solar GUI software is included to provide a graphic user interface that relates important system information. For additional information, see "Computer Communications with the PV100S" in the Operation chapter of the

PV100S 100 kW Grid-tied Photovoltaic Inverter Operation and Maintenance Manual.

The GUI can dial up the inverter and receive fault report calls from it through a standard Hayes-compatible, landline modem. When the GUI initiates a call through the modem at the GUI computer, the inverter’s modem answers the call and initiates a 9600 baud serial connection, effectively as if the GUI was connected directly. Or, if the inverter experiences a fault, it will initiate a call to the GUI and report the fault details.

Planning

Chapter 2, “Planning” provides information to help you plan the installation of the PV100S 100 kW Grid-Tied Photovoltaic Inverter.

Planning

Overview of PV100S Installation

WARNING: Shock Hazard

Installations of this equipment should only be performed by qualified technicians. Installers must meet all local and state code requirements for licensing and training for the installation of Electrical Power Systems with AC and DC voltage to 600 volts.

Planning Planning for a system requires complete understanding of all the components that

are involved to successfully install the PV100S to meet the required national, state, and local codes.

Definition A power system (such as the PV100S) is a collection of devices designed to

supply AC power to the utility grid from a solar energy (PV) source.

Components All types of grid-tied inverter installations, residential or industrial, share common

components. This chapter describes each component and suggests the minimum requirements for a safe installation.

Location The PV100S 100 kW Grid-Tied Photovoltaic Inverter is designed to be installed

in either an indoor or outdoor location. The PV100S must be anchored to a level concrete floor or pad.

Ideally the AC Interface Enclosure/Transformer assembly is placed on the left side of the Main Inverter Enclosure. The AC Interface Enclosure/Transformer assembly may be co-located adjacent to the left side of the Main Inverter Enclosure up to, but not exceeding, 15 feet away. See “Layout Options” on page 2–6.

Clearance Adequate ventilation and service access must be taken into consideration when

installing the PV100S. See “Ventilation and Serviceability Requirements” on page 2–3 for specific clearance requirements and ambient temperature requirements.

Conduits and Conductors

Given the flexibility to co-locate the AC Interface Enclosure/Transformer assembly to fit a desired system layout, the conduits and conductors are to be supplied by the installer.

See “Conduit Penetration” on page 2–8 for recommendations on enclosure penetration locations and conduit routing.

See “Conductor and Conduit Sizing” on page 2–11 for information on sizing the conductors and conduits.

All interconnect wiring and power conductors interfacing to the PV100S must be in accordance with the National Electrical Code ANSI/NFPA 70 and any applicable local codes.

2–2 152973 Rev A

Large gauge wire must conform to the minimum bend radius specified in the NEC, Article 373-6B, Ninth Edition.

T ake care to keep the wire bundles away from any sharp edges which may damage wire insulation over time.

All conductors should be made of copper and rated for 90 °C (minimum). If the installation of the PV100S is to be outdoors, all interconnect conduit and

fittings must be NEMA 4 rated as required by the NEC.

PV Planning

To determine the number of photovoltaic panels that are required for the PV power plant, please use the PV planning tool from the Xantrex website:

http://www.xantrex.com/support/pvsizing/disclaimer.asp

Ventilation and Serviceability Requirements

The following environmental conditions must be established and maintained to ensure the safe and efficient operation and servicing of the PV100S. Adequate space must be provided around the unit for ventilation and access during servicing. If locating the unit indoors, ambient air temperature cannot exceed the maximum temperature for which the unit is rated.

PV Planning

Ventilation Maintain a minimum clearance of 12 inches on both sides and 6 inches behind the

Main Inverter Enclosure and the AC Interface Enclosure for proper cooling fan operation.

Maintenance and Serviceability

Indoor Temperature Control

Maintain a minimum clearance of 36 inches in front of the main inverter access door, the Transformer Enclosure access panel, and the AC Interface access door for maintenance and serviceability.

See Figure 2-1 on page 2–6 and Figure 2-2 on page 2–7 for illustrations of these clearance requirements.

If the PV100S is to be installed indoors and external air is used for ventilation, the required cubic feet per minute (CFM) rate must be no less than 1000 CFM. This assumes the temperature inside the building is allowed to rise only 10 °C above the outside temperature. Therefore, the maximum allowable outside ambient temperature is 50 °C (50 °C minus 10 °C equals 40 °C Maximum Am bient Temperature). (See “Environmental Specifications” on page 1–6).

If air conditioning is planned for an indoor installation, the heat load of the PV100S is 1800 BTU/Hour at full load.

152973 Rev A 2–3

Planning

Ground Requirements

This product is intended to be installed as part of a permanently grounded electrical system per National Electrical Code ANSI/NFPA 70. A copper ground rod must be installed within three feet of the PV100S enclosure. This is the single point earth ground for the inverter system. 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

Communication Requirements

The PV100S can accommodate any one of the following options for PC Communication:

• POTS Connect Kit uses a MultiTech® 56K Modem, RS232/Fiber Optic Converter (configured for Ethernet) and SA2 Surge Arrestor. A direct analog phone line to the local phone service is required to use this feature. The phone line used for PV100S communication cannot be routed through a Private Branch Exchange (PBX) unless an analog PBX card is used.

• Wireless Connect uses a GSM Wireless Modem.

• Ethernet LAN Connect uses a data communication device to enable the unit to connect to a LAN.

• Direct Connect Kit uses a RS232/Fiber Optic Converter (configured for a PC), a DB25-to-DB25 gender changer, and a DB25-to-DB9 Serial Cable.

Determine which communications options are required for the installation and procure the appropriate service or phone access. The PC to be used with this unit must have the appropriate hardware as well, such as a 56K modem for dial up connection or a Network Interface Card (NIC) for a LAN connection.

Utility Side Isolation Transformer Requirements

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.

Conductor and Conduit Sizing

All wiring methods and materials shall be in accordance with the National Electrical Code ANSI/NFP A 70. When sizing conductors and conduits interfacing to the PV100S, both shall be in accordance with the National Electrical Code ANSI/NFPA 70, as well as all state and local code requirements.

Large gauge wire must conform to the minimum bend radius dependent upon the wire gauge (refer to the National Electrical Code, Article 373-6B (Ninth Edition).

CAUTION: Equipment Damage

Be careful to keep the wire bundles away from any sharp edges which may damage wire insulation over time.

The following section provides information on sizing the conductors and conduits for the system.

To calculate the proper conduit size:

1. Determine the required cable ampacity.

2. Determine the conduit length between the inverter and the transformer.

Conductor and Conduit Sizing

3. Determine the proper size for the cable according to the allowable ampacities indicated by NEC Table 310.16 or 310.17 (Ninth Edition).

4. Determine the proper size for the conduit.

The following section is an example of the steps outlined above. Assumptions were made in this example which may not match your application, and the resulting design may not comply with all code requirements. Consult a licensed electrician on recommendations for specific installations.

Step 1. Determine the required cable ampacity.

AC Phase Cables from Inverter to Transformer:

100 kW / 208 Vac / 1.732 = 277.5 A

277.5 x 125% = 347 A (required ampacity)

Step 2. Determine the conduit length between inverter and transformer.

• If the conduit length between the inverter and the transformer is less than 24 inches, then the cable can be sized using the NEC Table 310.17 (Free Air) (Ninth Edition).

• If the conduit length is greater than 24 inches, then the cable must be sized using NEC Table 310.16 (in Raceway) (Ninth Edition).

(full load current)

rms

152973 Rev A 2–11

Planning

Step 3. Size the cable.

This example assumes that the conduit length is less than 24 inches. NEC Table 310.17 (Ninth Edition) indicates the Temperature Correction Factor for 90 °C THHN cable in a 50 °C ambient is 0.82. With a required ampacity from Step 1 of 347 amps, it can be calculated that the required cable ampacity at 50 °C in this application is 423 amps. (347 divided by 0.82)

In this example, a single cable is desired, so from NEC Table 310.17 (Ninth Edition) it is apparent that the 90 °C THHN cable must be 250 KCMIL or larger.

Step 4. Size the conduit.

In this step, the cross sectional area of all the individual cables is first calculated. Once calculated, the total cross sectional area of the cables is determined by summing their values. In this example, 262 KCMIL DLO, 2000 V cable is selected for the AC Phase connections:

DLO 262 Cable:

262 KCMIL DLO, 2000V, 90 °C per Phase 262 KCMIL has an O.D. of 0.973

0.973 x 0.973 x 3 x 0.7854 = 2.23 in²

Ground Cable:

1 Each #2 AWG (per NEC Table 250.122 (Ninth Edition), using 400 A Breaker)

#2 AWG has an O.D. of 0.384 for THHN and 0.565 for DLO

0.565 x 0.565 x 0.7854 = 0.250 in²

Sense/Control Wires:

8 Each #16 AWG, UL1015, THHN, Hook-up Wire #16 AWG has an O.D. of 0.096

0.096 x 0.096 x 8 x 0.7854 = 0.058 in²

Total:

2.23 + 0.250 + 0.058 = 2.538 in²

Using the "Over 2 Wires" column per NEC Chapter 9, Table 4, (Ninth Edition) indicates that the following minimum permitted conduit trade size is acceptable for the 12 wires in this exercise:

EMT = 3" Trade size IMC = 3" Trade size RMC = 3.5" Trade size

2–12 152973 Rev A

Anchoring the PV100S

The PV100S is designed to be installed in either an indoor or outdoor location. The PV100S must be placed on and anchored to a level concrete floor or pad. The concrete floor or pad must be structurally designed to meet any local, state, or national requirements for weight, seismic, and wind sheer if applicable. The concrete floor or pad should either be pre-drilled to accept masonry anchors or have pre-installed anchoring bolts.

Conduit Installation

Given the flexible nature of the system, conduit installation will be dependent upon the final configuration of the system. Procurement and installation of the conduit, therefore, is the responsibility of the installer. Since the layout will be dependent upon the location available for the installation and the size of the conductors used, specific conduit size and type must be pre-determined by the installer before the actual installation. See “Conductor and Conduit Sizing” on page 2–11 for instructions on how to determine the size of the conductors and conduits to be used. Once the size of the conductors and conduits has been determined, follow the instructions below for installing the conduits. Be sure to consult the NEC Handbook and any local codes to ensure code compliance.

Conduit Installation

Important:

PV100S be NEMA 4 rated.

To install the conduits:

1. Determine the conduit penetration locations in the Main Inverter Enclosure and the AC Interface Enclosure/Transformer assembly. See Figure 2-3 on page 2–8 through Figure 2-5 on page 2–9.

2. Install appropriately-sized conduit based upon system layout and required codes between the Main Inverter Enclosure and the AC Interface Enclosure/Transformer assembly. For ease of conduit installation, the access panels on both the Main Inverter Enclosure and the AC Interface Enclosure/Transformer assembly can be removed.

3. Determine all remaining conduit penetration locations in the AC Interface Enclosure, DC Interface Enclosure, and Communication Enclosure. See Figure 2-3 on page 2–8 through Figure 2-8 on page 2–10.

4. Install all remaining appropriately sized conduit interfacing for the AC Interface Enclosure, DC Interface Enclosure, and Communication Enclosure based upon system layout and required codes.

System Neutral Requirements

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 affect 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.

Verification Procedure Summary

WARNING: Electrocution Hazard

This chapter describes specific steps to ensure the installation of the PV100S 100 kW Grid-Tied Photovoltaic Inverter is correct and complete. Failure to adhere to these warnings could result in severe shock or possible death. Exercise extreme caution at all times to prevent accidents. These installation instructions are for use by those familiar

and skilled with high voltage procedures.

WARNING: Shock Hazard

The PV100S enclosures contain exposed high-voltage conductors. The enclosure doors should remain closed with the latches tightened, except during installation, maintenance or testing. To reduce the risk of electric shock, do not perform any servicing other than that specified in the installation instructions unless you are qualified to do so.
