Introduction

Chapter 1, “Introduction” provides information about the features and

functions of the PV225S 225 kW Grid-Tied Photovoltaic Inverter.

Introduction

Description of the PV225S

The PV225S 225 kW Grid-Tied Photovoltaic Inverter is a UL 1741 Listed, utility interactive, three-phase po wer c onversion system for grid-connected photovoltaic arrays with a power rating of 225 kW. Designed to be easy to install and operate, the PV225S automates start- up, shutdown, and fault detection scenarios. With user-defin able power tracki ng that matc hes the inv erte r to the a rray and ad justabl e delay periods, users are able to customize start up and shut down sequences. Multiple PV225S inverter s are easily paralleled for larger power installations .

The PV225S power conversion system consists of a pulse-width modulated (PWM) inverter, switch gear for isolation and prote ction of the conne cted AC and DC power sources, and a custom high-efficiency Wye:Wye isolation transformer. Housed in a rugged NEMA-3R rated, powder-coated steel enclosu re, the PV225S incorporates sophisticated Intellimod (IGBTs) as the main power switching devices. An advanced, field-proven, Maximum Peak Power Tracke r (MPPT) integrated within the PV225S control firmware ensures the opti mum power throughput for harvesting ener gy from the photovoltaic arra y.

The advanced design of the PV225S 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 nuisanc e utility-tie circuit breaker trips as the result of isolation transform er inr u sh current.

(IPM) Insulated Gate Bipolar Transistors

Additionally, the PV225S integrated controller contains self-protection features including over and under volt age and frequency safeguards. An integral anti-island pro tection sch eme prevents the in verter from feeding power to the grid in the event of a utility outage. The PV225S includes a local user interface comprised of an O user-frie ndly, Graphic User Interface (GUI) provides a remote interface for operator interroga tion of PV225S system status, control, metering/data logging and protective functions within the PV225S. The status, control, and logging features are also supported by the choice of three communication mediums, allowing the informat ion to be acce ssed or commanded remotely.

The PV225S comes in two modules comprised of six enclosur es to house the electronics descr ibed above. The first module includes the Main Inverter Enclosure, Inductor Enclosure, DC Interface Enclosure, and Communications Enclosure. The sec ond 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 dimens ions and locations of the var ious enclosures that comprise the PV225S.

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 pe r the National El ectric Code ANSI/NFPA 70. A copper gro und rod must be installed within thr ee feet of the PV225S enclosures and connec ted 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 (TB12) in the AC Interface En clo sur e.

System Neutral Requirements

The PV225S is designed to be installed as a 4-wir e system. As required by the UL 1741 listing, a neutral conductor from the util ity-interconnect must be terminated at TB11 within the AC Interface Enclosure to ensure that the AC voltage sensing circuit can per form 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 essentiall y at ground potential. No power will flow through the neutral conductor.

Utility Side Isolation Transformer Requirements

The PV225S 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 tr ansformer are configured Wye and must match the voltage at the utilit y inter-tie. The PV225S is a balanced, three -phase, current-sourcing inverter and only operates with the pres ence 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 grou nd refer ence 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 PV225S. Check local regu lations for their requirements regarding the connec tion of the neutral.

WARNING: Lethal Voltage

Grounding the neutra l of a W ye -wound transfor mer may create an “open delta ” condit ion , depending on the utility configuration. This condition may keep the PV225S from detecting a loss of phase condition on the utility system, which may allow potentially lethal volta ge to be present on the open-pha s e wiring.

Introduction

PC Connection Methods

Personal computers can be used to access the system status and programming features of the PV225 S. A computer can be connected either dir e ctly or remotely.

1. Remote Connect - uses one of the three kits below.

• POTS Kit - uses a MultiTech® 56K Modem, RS232/Fiber Optic

• Wireless Kit - uses a GSM Wireless Modem.

• Ethernet LAN Kit - uses a da ta communication device to enable the unit

2. Direct Connect - This method is used for troubleshooting. It uses a RS232/Fiber Optic Converter (configur ed for a PC), a DB25-to-DB25 gender changer , and a DB25-to-DB9 Serial Cable.

Software is included to provide a graphic user interface that relates important system information. This software is called Xantrex Solar Graphic Interface (GUI). See "Computer Communications with the PV225S" in the PV225S 225 kW Grid-Tied Pho tovoltaic Inverter Operation and Maintenance Manual for additional infor mation.

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 mode m at the GU I comp u ter, the inve rter’s modem answers the ca ll 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.

Ventilation and Serviceability Requirements

The following environment al conditions must be established and mainta ine d to ensure the safe and efficient operation and servicing of the PV225S. Adequate space must be provi ded aro und t he unit for v ent ilat io n and access during servicing. If locating the unit indoors, ambient air temper ature cannot exceed the maximum temperature for which the unit is rated.

Ventilation Maintain a minimum cleara nce of 12 inche s 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

152606 2–3

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 PV225S is to be installed indo ors and external a ir is used for venti lation, 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 temperatur e. There fore, the maximum allowable outside ambient temperature is 50 °C (50 °C minus 10 °C equals 40 °C Maximum Ambient Temperature).

If air conditioning is planned for an indoor installation, the heat load of the PV225S is 42,000 BTU/Hour at full load.

Planning

Ground Requirements

This product is intended to be installed as part of a permanently grounded electrical syst em per National Electric Code ANSI/NFPA 70. A copper ground rod must be insta lled within three f eet of the PV225S enclosur e. This is the single point earth gr ound for the inverter s ystem. The single point ground for the system is to be made at the AC ground bus bar (TB12) in the AC Interface Enclosure.

System Neutral Requirements

The PV225S is designed to be installed as a 4-wir e system. As required by the UL 1741 listing, a neutral conductor from the util ity-interconnect must be terminated at TB11 within the AC Interface Encl os u re to ens ure that the AC voltage sensing circuit can perform an individual phase voltage (line-toneutral) measurement. The function of the neutr al connec tion is to provide a point of reference for measurement purposes that is essentially at ground potential. No power will flow through the neutral conductor.

Communication Requirements

The PV225S can accommodate any one of the following options f or PC Communication:

• POTS Co nn ect Kit - uses a MultiTech Converter (configu red for ethernet) and SA2 Surge Arrest or. A direct analog phone line to the local phone service is requir ed to use this f eature . The phone line used for PV225S 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 local area networ k.

• 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 installa tion and procure the a ppropria te ser vice or phone a ccess. The per sonal computer 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.

56K Modem, RS232/Fiber Optic

2–4 152606

Utility Side Isolation Transformer Requirements

The PV225S is supplied with a a high-eff iciency custom W ye:W ye isolation transformer as part of the AC Interface/Transformer assembly. The utility side windings of the isolation tr ansformer are configured Wye and must match the voltage at the utilit y inter-tie. The PV225S is a balanced, three -phase, currentsourcing inverter and only operates with the presence of a stable utility voltage. The transformer is also supplie d 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 grou nd refer ence at the utility distribution transformer.

CAUTION: Equipment Damage

WARNING: Lethal Voltage

Conductor and Conduit Sizing

All wiring methods and materials shall be in accordance with the National Electrical Cod e ANSI/NFPA 70. When sizing conducto rs and condu its i nterfa cing to the PV225S, both shall be in accordance with the National Electric Code ANSI/ NFPA 70, as well as all state and local code requirements.

Large gauge wire must confo rm to the minimum bend radius dependent upon the wire gauge (refer to the National Electric 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 provide s information on sizing the con ductors and conduits for the system.

To calc ul ate the proper condui t size :

1. Determ in e the req ui red cab l e am p acit y.

2. Determine the conduit length be tween the inverter and the transformer.

Conductor and Conduit Sizing

3. Determine the prope r size for the cable according to the allowable ampacitie s indicated by NEC Table 310.16 (Ninth Edition).

4. Determine the proper size for the conduit.

The following 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 Cab les from Inv erter t o Transfo rm er:

225 kW / 208 Vac / 1.732 = 624.5 A

624.5 x 125% = 780.69 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 310.16 (in raceway) (Ninth Edition).

• If the conduit length is greater than 24 inches, then the cable m ust be sized using NEC Table 310.16 (in Raceway) (Ninth Edit ion) and by using the adjustment factors in NEC Table 310-15(b)(2)(a).

(full load current)

rms

152606 2–11

Planning

Step 3. Size the cable.

This example assumes that the condui t length is less than 24 inches. NEC Table 310.16 (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 above of 780.6 amps, it can be calcul ated that the required cable ampacity at 50 °C in this application is 952 amps. (780.6 divided by 0.82)

In this example, four cables per phase termination are used, so from NEC Table

310.17 (Ninth Edition) it is apparent that the 90 °C THHN cable must be 262 kcmil or larger. Four each 262 kcmil conductors at 50°C have an allowable ampacity of 984 amps (246 multiplied by 4).

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 Phase Cable:

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

0.973 x 0.973 x 12 x 0.7854 = 8.923 in²

Ground Cable:

1 Each #2 A WG (per NEC Tabl e 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 A WG, 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:

DLO 262 Phase Cable = 8.923 in² (8.923 divided by 2 = 4.46) Ground Cable = 0.250 in² Sense/Control Wires = 0.058 in² 2 runs of conduit between the Isolation Transformer (T6-X1, T6-X2, and T6-

X3) and the Main Inverter Enclosure (T B5, TB6, and TB7) 1st conduit run; 4.46 + 0.25 = 4.71 in² 2nd conduit run; 4.46 + 0.058 = 4.52 in²

2–12 152606

Using the "Over 2 Wires" column per NEC Chapter 9, Table 4, (Ninth Edition) indicates that the fol lowing minimum permitted conduit trade size is acceptable for the 21 w i re s in this ex erc ise:

EMT = 3 ½" Trade size IMC = 4" Trade size RMC = 4" Trade size

Anchoring the PV225S

The PV225S is designed to be installed in eithe r an indoor or outdoor location. It must be placed on and anchored to a level concrete floor or pad. The concrete floor or pad, upon which the PV225S is anchored, must be structurally de signed to meet any local, stat e, or nati onal requi rement s for weight, seismic, and wind shee r if applicable.

Four 5/8" holes are provid ed in the feet of the main inve rter, and six 5/8" holes are provided in the feet of the AC interfa ce/t ransformer assembly for ancho ring to the floor or pad.

Array Grounding NEC Article 690-41/42 (Ninth Edit ion) requires the PV array to be earth

grounded. The PV225S chassis is al so bonded to the PV safety ground terminal block.

System Neutral Requirements

The PV225S is designed to be installed as a 4-wir e system. As required by the UL 1741 listing, a neutral conductor from the util ity-interconnect must be terminated at TB11 within the AC Interface Enclosure to ensure that the AC voltage sensing circuit can perform an individual phase voltage (line-to-neutr al) measurement. The function of the neutr al connection is to provide a point of reference for measurement purposes that is essentia lly a t ground potential. No power will flow through the neutral conductor.

Utility Side Isolation Transformer Requirements

The PV225S is supplied with a a high effic iency custom Wye :Wye isolation transformer as part of the AC interface/transformer assembl y. The utility side windings of the isolation tr ansformer are configured Wye and must match the voltage at the utilit y inter-tie. The PV225S is a balanced, three -phase,

current-sour cing 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 transf ormer and utility, will maintai n their existing grou nd refer ence at the utility distribution transformer.
