OVERVIEW

The following installation instructions detail installation procedures for photovoltaic modules, power optimizers, inverter, module racking systems and balance of system (BOS) components.

Prior to the installation of any grid connected PV system, a Site Visit shall be performed in accordance with the Clean Energy Council’s “Grid-Connected Solar PV Systems - Design Guidelines for Accredited Installers”.

SAFETY REQUIREMENTS

The voltages and currents produced by a single module or modules connected in series (voltages added together) or in parallel (currents added together) can be dangerous.

Although module DC plug connectors are insulated to provide touch safe protection, the following points must be observed when handling modules in order to avoid the risk of sparking, fire hazard, burn risk, and lethal electric shocks:

 Exercise extreme caution when wiring modules and look out for damaged or split cable ends.  Do not perform wiring work in rainy or damp conditions.  Never insert metallic or otherwise conductive objects into plugs or sockets.  Ensure that all electrical connections are completely dry and free from contaminants before they are

assembled.

 Ensure that connections are tight and correctly made.  Keep all materials, tools and work areas clean and dry.  Always use appropriate safety equipment such as insulated tools and wear personal protective equipment

such as insulated gloves.

 Solar modules produce current when exposed to sunlight. It is recommended that the system is shielded

with an opaque cover during installation, maintenance or repair work.

INSTALLER RESPONSIBILITIES

The installer is solely responsible for:  Observing and conforming to all relevant Australian Standards, all relevant Clean Energy Council

Accreditation guidelines and all applicable laws, ordinances, regulations, codes of practice and local or national building codes, including any that may have superseded these Installation Instructions.

 Ensuring that the installation complies with AS/NZS 3000, AS/NZS 5033, AS/NZS 1170.2,

AS/NZS 1562.1, AS 4777.1, AS/NZS 1768, AS/NZS 3008, AS 2050 and any relevant electrical service and installation rules for the state or territory where the system is installed.

 Ensuring that the PV System and associated components are appropriate for the particular installation

and the installation environment.

 Ensuring that the roof, roof rafters, battens, purlins, connections, and other structural support members

can support the total assembly under building live load conditions. The roof on which the PV system is to be installed must have the capacity to resist the combined Design Dead Load and Live Load at each mounting point.

 Ensuring only parts supplied by Solahart Industries and installer supplied parts as specified by Solahart

Industries are utilised (substitution of parts may void the warranty and invalidate certification).

 Ensuring that lag screws have adequate pull-out strength and shear capacities to suit the installation.  Maintaining the waterproof integrity of the roof, including selection of appropriate flashing.  Ensuring safe installation of all electrical aspects of the PV system.

OVERVIEW

DISCLAIMER OF LIABILITY AND WARRANTY

Solahart assumes no responsibility for loss, damage or expense resulting from improper installation, handling or misuse of PV modules. Refer to “Solahart PV System Warranty - Australia Only” on page 53 for full warranty terms and conditions.

IEC 61730 INFORMATION

Modules supplied by Solahart are designed to fulfil the criteria of application Class A requirements according to IEC 61730. Modules are qualified for application Class A: Hazardous voltage (Higher than 50 V DC) and hazardous power (higher than 240 W) applications where general contact access is anticipated. For the purposes of AS/NZS 3000, modules are classified as Class I equipment.

FIRE GUIDELINES

Utilise the following fire safety guidelines when installing modules supplied by Solahart:

 Modules supplied by Solahart have a Class C Fire Rating.  Check with local authorities for guidelines and requirements concerning fire safety for any building or

structure on to which the modules will be installed.

 The system design should ensure that fire fighting personnel can access the system in the event of a

building fire. Check with local authorities for any applicable regulations concerning setbacks or other placement restrictions that may apply for roof-mounted PV arrays.

 Any electrical equipment can pose a fire risk. Modules must therefore be mounted over a fire retardant

roof covering rated for the application and a distance of 60mm between the module and the mounting surface must be respected to allow free circulation of air beneath the module.

ENVIRONMENTAL FACTORS

Solahart’s limited warranty is based upon modules being installed in accordance with the following conditions:

 Modules are not suitable for installation in potentially hazardous locations.  Modules should not be installed in locations:

 near sources of flammable gases, vapours or open flames.  in direct contact with salt water/spray. Avoid installing in areas subject to high salt mist content.  which experience extreme hail and/or snow.  where they may be exposed to sulphur e.g. near sulphur springs or volcanoes  where they may be exposed to harmful chemicals.

WARNINGS

Warning: This document provides sufficient information for system installation heights up to 10 m. If the

installation site is more than 10 m in height contact Solahart Industries for further advice.

Warning: This system has not been certified for, and should not be installed in, wind region D.

Warning: During installation and when working on the roof, be sure to observe the appropriate OH&S safety

regulations and relevant regulations of your local region.

Warning: Ensure electrical connection/ disconnection is performed only when the relevant circuit is isolated. Do not connect / disconnect wiring under load conditions.

Warning: Do not expose the PV modules to artificially concentrated light.

Warning: Do not drill holes in the modules as this will void product warranty.

EARTHING ARRANGEMENTS – ALL SYSTEMS

Earthing connections must be made so the removal of one component (e.g. a module) does not interrupt the earthing to other parts of a system (e.g. other modules). Daisy chaining is not permitted. The PV system earth connection must be directly connected to the switchboard earth link, not via the inverter earth connection. If the earth cable could be exposed to direct sunlight, it must have a physical barrier to protect the earth cable from this exposure.

Earth wires must be sized in accordance with requirements set out in Earthing and bonding arrangements of AS/NZS 5033.

Solahart approved earthing plates may be used to earth modules via the racking, instead of wiring directly to the module frames. Refer to “Earthing” on page 31 for more information.

Warning: Do not drill holes in the modules as this will void product warranty.

The racking may be earthed by means of a rooftop isolator bracket. Refer to “Rooftop Isolator” on page 24 for details.

Where it is necessary to make an earthing connection to a rail that does not have a rooftop isolator bracket fitted, a rail splice piece will provide a suitable surface for connection. In this case, the splice should be attached to the end of the rail using both fixing bolts, and then the earth lug connected to the splice as shown in the figures below:

1. Slide rail splice onto end of rail, ensuring an overhang of approximately 50 mm.

2. Secure rail splice by tightening both Allen head bolts to 15 Nm.

3. Drill a hole in the centre of the rail splice, attach the earth cable using the earthing set supplied, and tighten

to 5 Nm.

INSTALLATION PROCEDURE

1. Planning – Design the system and layout. Refer to “Planning” on page 12.

2. Determine the spacing of the Rail Supports using the “Maximum Rail Support Spacing Tables” on page

18 and considering the following factors (refer to “Planning” on page 12): a. Wind Region b. Terrain Category c. Roof Type d. Roof Area e. Building Height f. Array Orientation

3. Install the Racking (Rail and Rail Supports). Refer to “Racking” on page 17.

4. Install the remainder of the roof top components as follows:

a. Rooftop Isolator. Refer to “Rooftop Isolator” on page 24. b. Rooftop Wiring. Refer to “Wiring” on page 25. c. Power Optimizers. Refer to “Power Optimizers (SolarEdge only)” on page 27. d. PV modules. Refer to “PV Modules” on page 30.

5. Install the inverter. Refer to “Inverter” on page 35.

6. Install the energy meter (optional component). Refer to “Meter (SolarEdge Only)” on page 39.

7. Install the system labels. Refer to “Labelling” on page 42.

8. Commission the PV system. Refer to “Commissioning” on page 44.

PLANNING

INSTALLATION TOOLS

 4,5 & 6 mm Allen keys or 4,5 & 6 mm Allen Key fittings to suit torque adjustable drill (for racking

components and inverter)

 Torx T20 screwdriver (ABB inverter systems only)  Cordless torque adjustable drill  Angle grinder with stone disk (for tile cutting if required)  Electricians hand tools (screwdrivers, pliers etc.)  String line  Timber to shim tile roof interfaces (if required)

STRUCTURAL ASSESSMENT

The installer is responsible for ensuring that the building and building structures are capable of withstanding the additional loads and forces generated as a result of installing the PV system. For domestic dwellings, it is recommended that a structural engineering assessment is completed. For all other installations, a structural assessment is required to be completed by a qualified structural engineer.

COMMUNICATIONS DEVICES

Complete installation of inverter communications devices requires the installer to register the communication

device and inverter on the inverter manufacturer’s web portal. Hence, to complete the communications

equipment installation, the installer must have access to the PV system owner’s internet connection. An

example of items that should be organised prior to onsite installation are:

 Confirmation that an internet accessible network port is available  Length of networking cable required from inverter to networking port  Wi-Fi access including SSID and password  PV system owner’s network administrator permission and assistance to adjust firewall, network

address translation (NAT) and port forwarding settings.

PV MODULE ORIENTATION AND INCLINATION

To maximize system output, install modules at optimum orientation and inclination (tilt) angles. The specifics of this will depend on the installation location and must be calculated by a qualified system designer. The ideal

angle for mounting a module should result in the sun’s rays falling perpendicular (i.e. at a 90° angle) to the

module surface. Note: All modules in each series string must have the same orientation and inclination to ensure that modules

do not underperform due to a mismatching of each module’s output. Modules should be installed in a shade free position. Even minor or partial

shading of the modules/array will reduce array/system output. A module is considered shade free when it is both:

 Free from shade or shadows all year round.  Exposed to several hours of direct sunlight, even during the

shortest days of the year.

Note: The following information is provided as a guide only:  Modules should be installed facing toward true north. Where this

orientation is not practical, a system facing up to 45° (NW or NE) from true north is satisfactory however losses of up to approximately 6% will occur. A module facing due east or due west will experience a loss in performance of approximately 18%.

 Inclination of modules should be approximately equal to the local latitude angle. The latitude of some

Australian cities is shown in the “Latitude of Some Australian Cities” on page 13. Modules may be

PLANNING

installed at the roof angle for simplicity of installation and appearance, however, if inclination varies by ±15º or more from the correct inclination, performance losses of 4% or more will occur.

 Modules should be inclined at an angle of at least 10° to support the self-cleaning function of the

glass.

 Losses for incorrect orientation and incorrect inclination will be compounded.  If the roof angle is flat, adjustable or fixed tilt legs should be considered to optimise inclination

depending upon area.

 For an installation at right angles to (across) a tile roof pitch, landscape tile roof hooks are required.  Each module and its fittings including racking weighs approximately 25 kg.

WIND REGION

Use the wind region diagram shown below to determine the wind region of the installation site.

Wind region notes:

 Wind regions are predefined for all of Australia by Australian Standard AS/NZS 1170.2. The Wind

Region has nothing to do with surrounding topography or buildings.

 Most of Australia is designated Region A which indicates a Regional Ultimate Basic Wind Velocity of

45 m/s.

 Some areas are designated Region B (57 m/s). Local authorities will advise if this applies in your

area.

 Region C areas (66 m/s) are generally referred to as Cyclonic and are generally limited to northern

coastal areas. Most Region C zones end 100 km inland.

 Region D (80 m/s) Australia's worst Cyclonic Region between Carnarvon and Pardoo in WA.

PLANNING

TERRAIN CATEGORY

The terrain over which the approaching wind flows towards a structure must be assessed on the basis of the following category descriptions:

Terrain Category 2: Open terrain, including grassland, with well-scattered obstructions having heights generally from 1.5 m to 5 m, with no more than two obstructions per hectare, e.g. farmland and cleared subdivisions with isolated trees and uncut grass.

Terrain Category 3: Terrain with numerous closely spaced obstructions having heights generally from 3 m to 10 m. The minimum density of obstructions shall be at least the equivalent of 10 house-size obstructions per hectare, e.g. suburban housing or light industrial estates.

ROOF TYPE

Determine the roof type of the building where the PV modules are to be installed and select the appropriate rail support.

Rail support systems are available as follows:

ROOF AREA

Determine the installation area on the roof (roof position area). The diagrams below show roof position areas designated as “Edge Zone” areas and “Centre Zone” areas according to interface type.

Edge zone areas are subject to higher wind loadings and therefore will require closer rail support spacing.

Warning: If any part of the system array is located in one of the edge zones, the entire array must use the

support spacing specified for the edge zones.

PLANNING

Use the following diagram, tables and worked example to determine the minimum required roof area for the array when designing and installing with REC280TP modules.

Roof interfaces must be fixed to rafters or purlins under the roof cladding. Screw minimum embedment into timber rafters is 50 mm and 35 mm for timber battens.

Steel purlins must meet the following minimum requirements:

Roof interface

Minimum steel purlin specification

Metal roof interface

0.55 mm BMT 550 Grade or 0.75 mm BMT 450 Grade

Tilt leg interface

1.0 mm BMT 500 Grade

Note: Screws supplied with the roof interfaces are wood screws suitable for timber only. Screws used in metal purlins must be suitable for metal structures and have a TPI (threads per inch) of 14.

RACKING

RAIL SPACING

Rails should be spaced so that the module is clamped in the correct positions. In general, the rails may be spaced between 833 mm and 1249 mm apart for REC280TP modules and 843 mm

and 1259 mm apart for REC290TP2 modules.

RAIL OVERHANG

Rail end overhang must be no greater than 50% of rail support spacing. For example; if rail support spacing is 1200 mm, rail end overhang can be up to 600 mm. In this case, two rail support brackets can support a rail up to 2400 mm in length (1200 mm between brackets and 600 mm of overhang at each end).

TILE ROOF INSTALLATION

Note: The tile roof interface is only suitable for installation on timber rafters.

1. Determine and mark the position of the tile roof interfaces according to your plans. Remove the roof tiles at marked positions or, if possible, simply move the tiles up slightly.

2. Fix the tile roof interfaces to rafters using two M6 X 80 mm wood screws. Ensure a 50 mm minimum screw embedment into the rafters.

3. Warning: Tile roof interfaces must not press against roof tiles and must be fixed parallel with rafters. If necessary, pack underneath tile roof interfaces with timber.

Incorrect

Correct

4. Warning: Do not use tile roof interfaces as a climbing support as extreme loading of this point could cause damage to the tile below.

5. For thin tiles (such as slate, shingles) proceed directly to step 6.

For thick tiles (such as grooved tiles), if necessary, use an angle grinder to chase a recess (or remove raised groves) on the tile that covers the tile roof interface at the point where the interface protrudes through so that the tile lies flat.

For thick tiles it may also be necessary to cut a recess into the tile located below the tile roof interface.

Now proceed to installation of the rails. Refer to “Rail Installation” on page 23.

RACKING

6. For thin tiles (such as slate, shingles), a portion of tile must be cut and removed from the tile above the tile roof interface, creating a recess.

Suitable flashing must then be installed around the tile roof interface, with an overlap of at least 150mm at the edges of the recess.

Now proceed to installation of the rails. Refer to “Rail Installation” on page 23.

METAL ROOF INSTALLATION

Note: Screws supplied with the roof interfaces are wood screws suitable for timber only. Screws used in metal

purlins must be suitable for metal structures and have a TPI (threads per inch) of 14.

1. Determine and mark position of the metal roof

interfaces according to your plans. Pre drill through roof cladding (on top of crest) at planned locations. Place the supplied rubber gasket under the metal roof interface and ensure that a weatherproof seal is made between the interface and the roof cladding.

2. Fix the metal roof interface to the timber batten or rafter using the M6 x 90 mm screw supplied.

Ensure a 50 mm minimum screw embedment for rafters or 35 mm for timber battens.

If the interface is being fixed to metal purlins use screws suitable for metal structures with a TPI of

14.

3. Check the metal roof interface to ensure that the fastening screw tightly fixes sealing gasket without damaging roof cladding.

Now proceed to installation of the rails. Refer to “Rail Installation” on page .

RACKING

TILT LEG INSTALLATION

Note: Screws supplied with the tilt legs are wood screws suitable for timber only. Screws used in metal purlins

must be suitable for metal structures and have a TPI (threads per inch) of 14.

1. Determine and mark position of feet according to your plans. Pre drill through roof cladding (on top of crest) at planned locations. Place the supplied rubber gaskets under each foot and ensure that a weatherproof seal is made between the foot and the roof cladding.

2. Fix the foot to the timber batter or rafter using a minimum of two M6 X 80 mm screws.

Ensure a minimum screw embedment of 35 mm for timber battens and 50 mm for rafters.

If the interface is being fixed to metal purlins use screws suitable for metal structures with a TPI of 14.

Check the foot to ensure that the fastening screws tightly fix the sealing gaskets without damaging roof cladding.

Adjustable tilt leg foot

5. Loosen the leg telescopic section Allen head grub screws. Adjust the leg length according to your plans and tighten the grub screws to 17 Nm.

6. Fix the leg L bracket to the leg using the Allen head bolt, washer, retaining washer and nut and fasten loosely to allow for later adjustment.

RACKING

RAIL INSTALLATION

1. Install rails onto the roof interfaces. If the assembly consists of rails of different lengths, always begin with the shortest piece. Install the rail loosely onto the roof interfaces using the Allen head bolt, washer, retaining washer and Z-modules supplied (2 to 3 turns of the bolt are adequate for loose installation). Refer to step 2 for method of inserting Z-module into rail.

2. For easy use of Z-modules ensure that Allen head bolt threads do not project through lower side of Z-module so that the Z-module is free to move. Position Zmodules in rail channel as shown and fasten loosely with 2 to 3 turns of Zmodule Allen head bolt. The rail can then be freely moved along Z-modules.

3. Adjust the vertical and horizontal position of the rail by taking advantage of the long hole in the tile and metal roof interfaces and the still loose connection of the rail Z-modules.

4. Align all rail ends. For adjustable tilt legs: align the rail tilt

orientation (use a string line if necessary).

Tighten all previously loosely installed rail and feet Z-module Allen head bolts to a torque of 21 Nm.

5. To connect multiple rails together, slide a splice on to the rear side of the previously assembled rail. Tighten the first splice Allen head bolt to 15 Nm. Slide the next rail segment into the splice. An expansion gap at the rail joints is recommended. Leave a gap of approximately 10 mm between the rail joints and then tighten the second Allen head bolt to 15 Nm.

ROOFTOP ISOLATOR

When installing the rooftop DC isolator, a Solahart Rooftop Isolator Subassembly must be used and must be mounted to the rail by following the steps below. To help prevent UV degradation, the Rooftop Isolator Subassembly should be mounted as far from the north side of the array as possible.

When installing the rooftop isolator the following points should be observed:  Ensure the IP rating of the isolator enclosure is maintained and that no moisture can enter. The conduit

entry points must be on the lower end of the enclosure (i.e.: facing downwards) so that any water will run away from and not towards enclosure entry points. Screw cover caps must be installed and all mounting holes should be sealed with silicone to help prevent water ingress.

 Cable glands and conduit adapters must be chosen to suit the type of cable or conduit used. E.g. cable

glands designed for figure-8 cables must be chosen where figure-8 type solar DC cables are utilised.

 Any conduit adapters should be installed so that the conduit slopes downwards from the enclosure to

prevent water ingress in adverse weather conditions.

 If water and/or condensation can form in the isolator enclosure, provision must be made for its harmless

escape through suitably located drainage points in accordance with AS/NZS 3000 Clause 3.3.2.3. Conduit entering the isolator enclosure must have a drainage hole installed at the lowest point to facilitate the escape of any moisture.

Note: Install Rooftop Isolator Subassembly before installing any PV modules.

1. Determine where the Rooftop Isolator Subassembly is to be attached.

a. The Rooftop Isolator Subassembly is

configured for installation on the array as shown above.

b. If the Subassembly is to be fitted in the other

orientation, move the cover (with the Solahart logo) from position A to position B as shown above.

c. If in doubt, slide the subassembly into the rail at

the point of attachment (see Step 4) and check whether the Solahart logo is facing up.

2. Identify the earth connection point on the bracket, as shown above.

3. Connect the earthing wire to the connection point, as shown above, using a tightening torque of 5 Nm.

4. Slide the subassembly into the rail making sure that the Solahart logo is facing up (see Step 1)

5. Tighten both M8 bolts to 15 Nm, ensuring good connection between the bolts and rail.

WIRING

Only UV-resistant cables and connectors approved for outside use should be used. PV cable must be marked or labelled in accordance with AS/NZS 5033.

To minimise the risk of indirect lightning strikes, avoid forming closed loops when designing the system. Check to ensure that system wiring is correct before commissioning modules. If the measured open circuit voltage (Voc) and short circuit current (Isc) differ from specifications, a wiring fault may be present.

Recommended cable size for plug connectors is 4 – 6 mm2, with an operating temperature range of -40 to +120ºC. Plug connectors are polarised and should be firmly connected. All connections should be secure, tight and electrically and mechanically sound. Correct DC polarity should be observed at all times. Plug connectors should never be used to turn the system on or off (i.e. do not connect or disconnect plug connectors under load conditions).

Only use plug connectors supplied with your Solahart PV system, or which are the same type/model and from the same manufacturer as those on the PV module. Ensure that all plug connectors and plug wiring are in good electrical and mechanical condition and are not subjected to mechanical stress.

Ensure that all materials meet system requirements such as maximum voltage, current, moisture and temperature when exposed to sunlight.

Electrical ratings of the PV modules are within 3% of measured values at Standard Test Conditions (STC). Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than that reported under STC. When designing a system, allow for increased output of a module as a result of conditions different to STC in accordance with the Clean Energy Council’s “Grid-Connected Solar PV System - Design Guidelines for Accredited Installers” and AS/NZS 5033.

Ensure cables are fixed to the mounting structure and are not in contact with the roof or rear surface of module(s) by using restraining devices which are sunlight and UV-resistant.

Note: Plastic cable ties are not to be used as primary means of support. A roof flashing such as a Dektite® must be used where wiring penetrates tile or metal

roofing. Flashings must be sealed using an appropriate waterproofing compound such as silicone.

All wiring must be protected from mechanical damage and external wiring must be protected from UV and mechanical damage in such a manner that it will last the life of the system. All conduits shall comply with AS/NZS 2053.1 and if exposed to sunlight must be suitably UV rated and marked with the letter “T”. Do not install wiring such that it is subject to permanent tension.

DC ISOLATOR WIRING

The DC isolators utilised in Solahart PV Systems are not polarity sensitive (non polarised type) however for uniformity they should be wired as shown in the DC isolator wiring diagram below.

Warning: DC isolator terminal screws must be tightened by hand only. Do not use power tools.

DC isolator wiring

diagram

Once wired, the DC isolator should be left in the open position until system commissioning.

POWER OPTIMIZERS (SOLAREDGE ONLY)

Warning: Input and output connectors are not watertight until mated. Open connectors should be mated to

each other or plugged with appropriate watertight caps.

Warning: Cutting the power optimizer input or output cables is prohibited and will void product warranty. Warning: Do not connect / disconnect DC connectors or wiring while under load. Warning: Only connectors of the same make and model may be connected together.

Note: Modules with SolarEdge power optimizers output a low safety voltage before the inverter is turned ON.

As long as the power optimizers are not connected to the inverter or the inverter is turned OFF, each power optimizer will output a safe voltage of 1V (±0.1V).

MOUNTING THE POWER OPTIMIZERS

1. Determine and mark the power optimizer mounting locations on the rail:

a. Power optimizers should be spaced approximately 1009 mm (for REC280TP) or 1015mm (for

REC290TP2) apart on the rail. See figure below.

b. Power optimizers must be positioned so that they maintain a 25 mm clearance distance

between the power optimizer and other surfaces to allow for heat dissipation.

Note: Figure is not to scale.

Note: Ensure clearance between power optimizers and PV module junction boxes.

REC280TP: 1009 mm

REC290TP2: 1015 mm

REC280TP: 1009 mm

REC290TP2: 1015 mm

POWER OPTIMIZERS (SOLAREDGE ONLY)

2. Attach each power optimizer to the mounting rail using the Z-module assembly provided in the BOS kit.

See figure below. Apply a tightening torque of 9.5 Nm.

Z-module assembly

Note: It is recommended that the power optimizers be placed face down to ensure clearance between the back of modules and power optimizers. See figure below.

Note: Figure is not to scale.

3. Verify that each power optimizer is securely attached to the rail.

4. Record power optimizer serial numbers and locations. This can be achieved through the use of a paper

template or SolarEdge smartphone application. Refer to SolarEdge supplied documentation for more information.

POWER OPTIMIZER WIRING PROCEDURE

Warning: Use insulated tools and wear appropriate PPE when performing wiring to prevent the risk of

electric shock. PV Module and power optimizer DC plug connectors are connected as follows:

Firmly push positive (+) plug into negative (-) plug until an audible

“click” is heard, and then try to pull plugs apart. Incorrectly connected

plugs will come apart whilst correctly connected plugs will not come apart unless the locking latches on either side of the positive (+) plug are depressed using an unlocking tool whilst plugs are pulled apart.

Note: Pull on plugs, do not pull on wiring.

+ -

Warning: Do not connect / disconnect DC connectors or wiring while under load.

Warning: Only connectors of the same make and model may be connected together.

The following procedure should be adhered to whilst wiring power optimizer strings to prevent the risk of electric shock or inadvertent short circuiting of live cables whilst wiring the Rooftop DC Isolator:

1. Two extension leads per string should be constructed using the DC extension cable provided in the BOS

Kit. One should be short to connect from the first power optimizer in the string to the DC isolator. The other should be sufficiently long to plug the end power optimizer in the string to the DC isolator (see the example schematic below).

POWER OPTIMIZERS (SOLAREDGE ONLY)

2. Ensure the Rooftop DC Isolator is in the OFF position, strip 12 mm of insulation from the end of each

extension lead and connect the two extension leads to the Rooftop DC Isolator terminals. The Rooftop DC Isolator should be wired in a consistent manner. Refer to “DC Isolator Wiring” on page 26.

3. Connect the first power optimizer’s positive output (+) cable plug to the Rooftop DC Isolator extension

cable negative (-) plug. See figure below for power optimizer cable plug illustration.

Note: Image is for illustration purposes only. Refer to the label on the product to identify the plus and minus input and output connectors.

4. Connect each power optimizer’s negative output (-) cable to the following power optimizer’s positive output

(+) cable.

5. Connect the last power optimizer’s negative output (-) cable to the Rooftop DC Isolator extension cable

positive (+) plug.

6. Connect the first power optimizer’s input connectors to the first module’s connectors.

7. Repeat Step 6 for each module and power optimizer in the string.

8. Verify proper power optimizer connection by measuring the voltage of each string individually.

Note: Each power optimizer in the string will output a safe voltage of 1 V (±0.1 V). For example: 9 power optimizers connected in a single string should output a safe voltage of 9 V (±0.9 V).

Note: Ensure the modules are exposed to sunlight during this process; otherwise, the power optimizers may not be powered.

9. Repeat Steps 1 - 8 for each string in the PV array.

10. Your PV array wiring is now complete.

Note: The Rooftop DC Isolator should still be in the OFF position at the completion of this stage of the installation. It should not be turned ON until the correct stage of commissioning. Refer to “Solar Isolation Device(s) Test – Rooftop DC Isolator(s)” on page 45.

PV MODULES

PV modules generate electricity as soon as they are exposed to sunlight and as such they can represent a danger. All warnings in this manual must be observed when handling solar modules to avoid the risk of fire, sparking and/or electrocution.

If modules are connected in series (summing voltage) the combined voltage must not exceed the inverter’s maximum input voltage rating. For the maximum number of series connected modules permissible, refer to the relevant wiring diagram in this document for the inverter model installed.

The Solahart mounting system requires the use of modules of equal thickness for correct clamping. Note: Ensure only modules of the same type (model & thickness) are clamped side-by-side and electrically

connected.

MODULE HANDLING

Modules should be handled with care and protected from damage at all times. All warnings and instructions on the packaging should be observed. Follow these guidelines when unpacking, transporting or storing the modules:

 Note module serial numbers before installation and record serial numbers in the system documentation.  Carry modules using both hands and do not use the junction box or electrical wiring as a grip.  Do not subject modules or backsheets to loads or stresses.  Do not stand on the modules.  Do not use modules that have been dropped.  Keep all electrical contacts clean and dry.  Store modules in a dry and properly ventilated room.  Do not use sharp or pointed objects to mark module surface or module anodising.  Never apply paints, adhesives, or detergents to the rear laminate of the modules.  Never attempt to disassemble modules, modify or adapt the modules or labels in any way as this will

void the warranty.

 Do not drill additional holes in any part of the module. Drilling holes voids the product warranty.

Warning: Do not use modules which are broken or damaged. If the module front glass is broken or laminate

back sheet is damaged in any way, hazardous voltages may be exposed.

STRING WIRING PROCEDURE

Note: If you have completed the “Power Optimizer Wiring Procedure” on page 28, proceed to “Earthing” on

page 31.

Warning: Use insulated tools and wear PPE when performing wiring to prevent the risk of electric shock. It is suggested that modules be covered with an opaque material during wiring to reduce the voltage generated by the string.

PV Module DC plug connectors are connected as follows:

Firmly push positive (+) plug into negative (-) plug until an audible

“click” is heard, and then try to pull plugs apart. Incorrectly connected

Note: Pull on plugs, do not pull on wiring.

Warning: Do not connect / disconnect DC connectors or wiring while under load.

Warning: Only connectors of the same make and model may be connected together.

PV MODULES

The following procedure should be adhered to whilst wiring module strings to prevent the risk of electric shock or inadvertent short circuiting of live cables whilst wiring the Rooftop DC Isolator:

1. Two extension leads per string should be constructed using the DC extension cable provided in the BOS

Kit. One should be short to connect from the first module in the string to the DC isolator. The other should be sufficiently long to plug the end module in the string to the DC isolator (see the example schematic below).

2. Ensure the Rooftop DC Isolator is in the OFF position, strip 12 mm of insulation from the end of each

extension lead and connect the two extension leads to the Rooftop DC Isolator terminals. The Rooftop DC Isolator should be wired in a consistent manner. Refer to “DC Isolator Wiring” on page 26.

3. Connect the first module positive (+) cable plug to the Rooftop DC Isolator extension cable negative (-)

plug.

4. Connect each module’s negative (-) cable to the following module’s positive (+) cable as modules are

being installed until the halfway point is reached i.e. fourth module in an eight module string.

5. Install and connect the remaining modules, but do not make the halfway connection, i.e. in an eight module

string do not connect the fourth module negative (-) cable to the fifth module positive (+) cable (refer to wiring diagram below). These two cables will be connected at the end of this procedure.

6. Connect the last module’s negative (-) cable to the Rooftop DC Isolator extension cable positive (+) plug.

7. Complete the circuit by connecting the two string halves together by connecting the positive (+) and

negative (-) cables of the two modules left previously disconnected in step 5.

Note: Modules may be connected in a different order provided that all modules in a string are connected in series.

EARTHING

All modules and rails must be earthed. Refer to “Earthing Arrangements – All Systems” on page 10. Earthing connections must be made by a suitably qualified person according to the relevant standards outlined on page

4. It is also recommended that a reliable lightning protection system be installed. `Stainless steel serrated washers must be used so the rail anodising is pierced, providing good electrical continuity. Stainless steel nuts, bolts and washers must be used and all ferrous metal in conductive connections should be specially treated to prevent corrosion (i.e. by spray painting or coating with a galvanising paint). Refer also to “Earthing Arrangements – All Systems” on page 10.

Earthing plates

To earth modules and rails, use earthing plates supplied when mounting modules. Install earthing plates in accordance with the following instructions. When installed correctly, earthing plates will provide earth bond continuity between rails and modules whilst allowing removal of a module without affecting the earthing integrity of other components in the system. The rails must then be earthed by connecting a suitably sized earth wire. Refer to “Earthing Arrangements – All Systems” on page 10.

PV MODULES

Warning: Only Solahart approved earthing plates are to be used. Warning: Module frames must be located on top of earthing plate earth bond protrusions. Warning: Earthing plates are intended for single use only and must not be reused.

Warning: If rails are not of a continuous length, or rail splices do not provide satisfactory earth continuity, earth bond jumper cables must be used across rails or rail splices or each section of rail must have an earth wire connection.

MODULE MOUNTING

Ensure a minimum clearance of 60 mm between the outer surface of the roof and any part of the module to allow sufficient airflow beneath the modules and adequate cooling of the modules.

Module cables must be installed so that any water will run away from the junction box. Each corner of the module frame has small drainage holes to allow water caused by rain or snow melt to exit

the frame easily and to minimize damage caused by freezing and thawing. Please note:

 The drainage holes must not be used for mounting the module.  Ensure the drainage holes are clear at all times.

Fastening the modules to the mounting structure

Each module must be securely fixed to the mounting structure at a minimum of four points. The distance between the end clamp and the end of the rail should be a minimum of 25 mm. The mounting clamps must be fastened so the clamp lies completely within the range of shown below for each type of module.

Note: Figure is not to scale

PV MODULES

Module Mounting Procedure

1. Mid clamps and end clamps can be inserted into the rail by following the procedure shown, making sure the spring washer is correctly in place.

For easy use of Z-modules, ensure Allen head bolt threads do not project through lower side of Z-module, so the Z-module is free to move along the rail.

2. In positions where earthing plates are required, slide the earthing plate over threaded section of Allen head bolt and press earthing plate into rail so that rail retention tabs hold the earthing plate in position.

3. Install PV module under end clamps. Ensure end clamps are tight against the module and are at least 25 mm from the rail ends. For end clamps with earthing plates, ensure the frame of the module is located on top of the protrusions of the earthing plate. Tighten end clamp bolts to 21 Nm.

INVERTER

For inverter installation instructions and warranty exclusions refer to the documents supplied with the inverter. The following points must also be observed when installing the inverter:

Warning: Inverters have masses between 9 kg and 27 kg. Proper safe handling procedures must be

employed when installing or handling these inverters.

 Inverters must be sheltered from direct sunlight and other sources of heat.  Inverters must be installed in a well-ventilated place so as to allow good circulation of air around the

unit. Avoid places where air cannot circulate freely around the unit.

 The inverter must not be installed in a location accessible to children.  The mounting structure must be capable of supporting the inverter weight.  If the inverter is to be mounted on a combustible surface such as wood, a heat resistant backing (such

as a fibre cement board) must be installed behind the inverter. Backing must extend a minimum of 20 mm past all edges and sides of the inverter.

 Inverter mounting clearances and requirements outlined in the relevant inverter documentation must

be adhered to. Ignoring recommended mounting instructions can cause permanent damage to the inverter from water ingress and can reduce inverter efficiency due to inadequate heat dissapation..

 Sealing plugs provided with the inverter must be inserted into any unused string inputs to maintain the

inverter’s IP rating. For SMA inverters, sealing plugs must inserted into the rear of the Sunclix DC plug connectors. For ABB and SolarEdge inverters verify the presence of watertight rubber cap seals on DC input connectors and install them should they be absent.

 For the ABB PVI single phase inverters ensure that:

o For multiple string systems, the inverter is configured for ‘independent’ channels (factory

default setting).

o For single string systems, the inverter is configured for ‘parallel’ channels. Refer to inverter

documentation for detailed instructions on configuration of channels.

 When installing an inverter with a StorEdge Connection Unit, do not install fuses if a battery is not

installed. Leave all fuses in their original packaging behind the plastic cover inside the StorEdge Connection Unit, clear from all electrical wires and components.

MULTI-CONTACT DC CONNECTIONS

Multi-Contact Safety Locking Clips must be installed over the negative connectors of all Multi-Contact DC connections at the inverter. The purpose of these devices is to prevent accidental disconnection of live DC at the inverter. When the Safety Locking Clip is in place, a custom tool is required to separate the connectors.

COMMISSIONING

Systems must be commissioned according to AS/NZS 5033. Commissioning tests are required to ensure that the system complies with the aforementioned standard. Commissioning information is provided here as a guide only and it is the installer’s responsibility to ensure that the requirements of AS/NZS 5033 are met. A copy of the relevant commissioning documents must be provided to the owner and a copy kept by the installer.

Before starting any of the tests below, ensure that:

 The Main Switch (Inverter Supply) at the AC switchboard is in the OFF position.  The Inverter AC Isolator at the inverter is in the OFF position (if installed).  The Inverter DC Isolator(s) at the inverter are in the OFF position.  The Rooftop DC Isolator(s) are in the OFF position.

Warning: Dangerous DC voltages may be present during the following commissioning procedure.

Appropriate personal protective equipment should be used.

VERIFICATION OF MODULE AND RAIL EARTH RESISTANCE

This test is performed to ensure modules and rails are correctly earthed.

1. Using a multimeter set on the ohms scale, measure between each module and the system earth wire.

Earth resistance must be 0.5 Ω or less.

2. Using a multimeter set on the ohms scale, measure between each rail and the system earth wire. Earth

resistance must be 0.5 Ω or less.

STRING OPEN CIRCUIT VOLTAGE (VOC) TEST

This test is performed to ensure the wiring polarity and continuity of the PV array is correct. Measurements should be made under stable irradiance conditions close to solar noon if possible. Where multiple strings are installed, this test procedure must be repeated for each string.

The voltage measurement obtained should be the number of modules in the string multiplied by the Voc of one module i.e. for a string with 9 X REC280TP modules: String Voc = 9 X 39.2 V DC ≈ 353 V DC. Refer to “Voltage Tables for SMA and ABB Systems” or “Voltage Tables for SolarEdge Systems” on page 9.

1. Ensure that the Inverter AC Isolator(s) are in the OFF position.

2. Ensure that the Inverter DC Isolator(s) are in the OFF position.

3. Ensure that the Rooftop DC Isolator(s) are in the OFF position.

4. Using a multimeter set on the DC voltage scale, measure between the string positive and negative

terminals at the module side of the string Rooftop DC Isolator and compare the value obtained with the table below. For SolarEdge systems see note below.

Note (SolarEdge systems only): Each power optimizer in a string will output a voltage of 1 V (±0.1 V). For example: 9 power optimizers connected in a string should output a voltage of 9 V (±0.9 V).

5. Repeat for each string.

The open-circuit voltage (Voc) of every string must be measured before switching on the inverter and must be within 5% of the calculated value. If readings are outside the calculated value by more than ±5%, then connections must be verified for polarity, continuity and possible faults and repaired where necessary. Once verification has been satisfactorily completed, strings may then be connected to the inverter.
