1�- RECEPTION, TRANSPORT AND HANDLING

CIRCUTOR has a standard range of EFM-Pving PARK kits for instantaneous self-consumption in network connected photovoltaic energy installations that range in power from 1.92 kW to more than 22 kW.

Each kit has a product sheet with detailed descriptions of the products included in the kit along with their technical features, weights and dimensions. Updated versions of these sheets are always available in the product section of the CIRCUTOR website www.circutor.es

EFM-PVing PARK kits are sent as a single shipment and with all the material included (material cannot be sent separately or to different shipping addresses). It is essential that you download the information corresponding to your kit to find out about the elements and their dimensions and weights in order to prepare for their shipment logistics, storage and installation.

1.1.- RECEPTION PROTOCOL

- Make sure that the material has not been damaged during transport. - Check that the material received matches your order and that its electrical features

are suitable for the network to which it is to be connected. - Check the shipping documentation. The delivery note number must match the number marked on the outer part of the pallets received.

- Follow the instructions in section 1.2 for unloading and transporting the material. - Perform an external and internal visual inspection of the material prior to installing and connecting it. - Check that you have all the items listed in the delivered documentation.

If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service

1.2.- TRANSPORT, LOADING-UNLOADING AND STORAGE

The transport, loading and unloading and handling of the material must be carried out with proper precautions and using the proper manual and me-chanical tools to avoid damaging it.

The centre of gravity of some units may be found at a considerable height. Therefore, when handling with a forklift, we recommend that the unit be se-curely fastened and that no abrupt manoeuvres made. The unit should not be lifted more than 20 cm above the ground.

EFM-PVing PARK KIT

Installation Guide

Figure 1:Transport with pallet jack

If the material is not to be installed immediately, it should be stored in a place with firm, level ground. In this case, we recommend that the material be stored in its original protective pack-aging.

The unit should be stored according to the following recommendations:

- Avoid placing it on uneven surfaces. - Do not store in outdoor areas, humid areas or areas exposed to splashing water. - Avoid hot spots (maximum ambient temperature: 45 ºC) - Avoid salty and corrosive environments.

- Avoid storing the material in areas where a lot of dust is generated or where there is a risk of chemical contamination or other types of pollution.

- Do not place any weight on top of the cabinets of the units.

When unloading and moving the unit, use a forklift with forks long enough to support the entire length of the base. Otherwise, the forks should be long enough to support the entire depth of the unit. The forks must be flat and supported firmly by the base. Raise the pallets with the ma-terial by placing the forks underneath the frame that supports the unit. (Figure 2).

There might be an offset in the centre of gravity from the centre of the cabinet, as a result of the uneven distribution of loads inside the unit. The necessary precautions must be taken to prevent the unit from tipping over during abrupt operations.

EFM-PVing PARK kits for self-consumption include the following materials:

Mechanical structure consisting of the following elements: ▪ Feet anchors. ▪ Feet. ▪ Struts. ▪ Beams. ▪ Fasteners such as screws, washers, etc. Photovoltaic modules Photovoltaic inverters

Monitoring, measurement and control elements (CDP, CVM-MINI, current transform-ers, etc.). Electric panels (Combiner box and String box suitable for each kit) with AC and DC protection as well as monitoring and control features.

Optionally: Electric vehicle charging point. CIRCUTOR's web monitoring system and electric energy management system.

It is essential to respect the design and architecture of each kit. Each kit has been designed to be installed in a specific way, with a certain number of modules connected in series and a certain number of strings per invert-er. Modifying the architecture envisioned for each kit could cause electrical damage to units and physical harm to people.

2.1. - GENERIC DESCRIPTION OF EACH KIT

EFM-PVing PARK are solar photovoltaic energy generator parking kits which intrinsically fulfil two functions: serving as a car park to give parked vehicles protection against the rain during the winter and shade during the summer and, at the same time, integrating a renewable electri-cal energy generation unit.

The solar car parks are built with machined, welded and galvanised structures to allow the photovoltaic generation unit to be attached to them. The surface of this structure has been de-signed and optimised to offer high performance in terms of personal safety, to the photovoltaic unit, energy production, structural strength and aesthetic criteria.

Table 2 details the composition of each of them, showing the solar generator power and num-ber of modules, parking spaces that they have, dimensions (height x depth x width), power of inverter included and the type of network where they will be connected:

Figure 7:Approximate dimensions of photovoltaic modules

Note: CIRCUTOR reserves the right to modify the supply conditions of photovoltaic modules, while guaranteeing optimal quality and updated technical features of the kits at all times.

2.4.- DESCRIPTION OF THE SOLAR INVERTERS

Solar inverters transform the direct current power supplied by the photovoltaic modules into voltage and alternating current so that it may be used for consumption.

CIRCUTOR sizes each kit with a specific combination of inverter models that have the nominal powers to achieve these objectives.

The range of inverters in CIRCUTOR's EFM-PVing PARK kits allows configurations from 2 kW to 22.5kW. CIRCUTOR uses the most appropriate inverters to achieve an optimal level be-tween the required generation power (Wp) and the nominal power of the inverter(s).

All the configurations of the solar generator have been dimensioned to work in the most critical ranges of ambient temperature and solar radiation, respecting all the recommended electrical limits from inverter manufacturers and ensuring compliance with Spanish low-voltage regula-tions (REBT).

Note: CIRCUTOR reserves the right to modify the supply conditions of the solar inverters, while guaranteeing optimal quality and the updated technical features of the kits at all times.


EFM-PVing PARK KIT

2.5.- DESCRIPTION OF THE CONTROL / MOTORIZATION SYSTEM

The type proposed for this model of solar generator is “Instantaneous self-consumption with zero injection” for different nominal inverter output power ratings in AC.

The units of the CIRCUTOR CDP (Dynamic Power Control) product family instantly adapt the production power of photovoltaic inverters to the consumption demand at all times. This means we ensure zero injection into the electrical network. The CDP units also enable both the direct and remote monitoring of the system's energy flows via an Internet connection. They also offer data storage capacity and the activation of an aux-iliary relay as redundant reverse current protection, in compliance with the requirements of the distribution companies.

Apart from the main dynamic power controller function (real time dynamic adaptation of the inverter's generation power based on consumption in the installation), the CDP device includes the following functions:

Web server allowing the data for the main parameters of the solar installation to be monitored and stored locally and remotely.

Measurement and recording of electrical parameter data on the installation consump-tion and energy input from the electrical network in real time.

Control of reverse current relay, whereby redundant safety is added to ensure zero injection into the grid, as required by some distribution companies.

Optionally, according to the customer's requirements and specifications, it is possible to add all the monitored variables of the solar canopy to a WEB manager (PV Monitor), which will en-able the joint display of the solar installation, charging of the electric vehicle and electric energy management of the building.

The PV Monitor is an energy management system (EMS) which includes PowerStudio (Web server + XML) designed for instantaneous photovoltaic consumption applications (with or with-out injection into the grid). It includes SCADA monitoring software which provides it with infor-mation on energy production in real time, energy savings and the load consumption of a build-ing, home, company, etc.

14

EFM-PVing PARK KIT

Installation Guide

Figure 8: PV Monitor

The service features for the SCADA application are as follows:

Instantaneous energy balance between the distributor, PV generation and consump-tion

Indicators for months in progress: PV production and savings Instantaneous environmental data Calculation of performance rate [PR] Percentage representation of solar fraction for month in progress [PV / Grid] Alarm setup

PowerStudio SCADA is a more advanced monitoring option, which is included when the charging point is external (RVE2-PM-MIX). PowerStudio is a simple, powerful and user-friendly software application, with which you can perform or calculate:

High-level energy studies Production ratios (know energy consumption per unit produced) Network quality management Use of acquired information for graphs or tables.

It allows full monitoring of power analyzers, meters, earth leakage and complete control of dif-ferent magnitudes in the photovoltaic field.

The advantages of this option are:

Offers full management and monitoring of installation data Customisation of screens Creates reports Customised alarms


EFM-PVing PARK KIT

2.6.- DESCRIPTION OF THE ELECTRIC PANELS

CIRCUTOR's CDP CB PV / SB electric panels (Combiner Box and String Box) group togeth-er all the required DC and AC electrical protection elements so that users can have the entire solution in a single cabinet.

In addition to the protection elements, the CDP CB PV / SB Combiner Box range comes with a CDP-0, which guarantees that users can manage zero injection into the electrical grid, as well as a CVM-MINI power analyzer (for three-phase installations) for measuring energy exchanges with the network.

The CDP CB / PV /SB range is designed to complement the EFM-PVing PARK series with zero injection into the grid, facilitating the installation and reducing the assembly time.

Main elements:

CDP-0 (Dynamic power controller to regulate inverters, measure consumption and guarantee zero injection into the grid). CVM-MINI power analyzer for measuring electrical parameters (for three-phase instal-lations). Ultra-immunised earth leakage relay, toroidal earth leakage transformer and circuit breaker with a trip coil (RGMD type). Circuit breakers for protecting each inverter. Circuit breakers for power supply of monitoring and control equipment. Overvoltage protection (DC and AC) with visible indication of tripping.

Fuses with a fuse carrier base. Contactor included as a redundant safety measure to avoid injecting current into the grid.

Optionally according to EFM-PVing PARK specification:

EDS Scada Manageable router

Different electric panels are used for different EFM-PVing PARK kits. Each electric panel (one or several units) is specifically designed to meet the requirements of the EFM-PVing PARK kit that it comes with.

Each electric panel has a terminal strip for connections with labels describing each terminal. These terminals are identified the same way as the elements in the installation diagram for the EFM-PVing PARK kit are identified; this diagram comes with the product and is available in digital format on the web site (www.circutor.es).

The range of electric panels for CDP CB self-consumption photovoltaic energy installations covers all the references for available EFM-PVing PARK kits.

2.7.- DESCRIPTION OF THE CIRCUTOR CHARGING POINTS (OPTIONAL)

One of the main objectives of the solar canopy solution is electric vehicle charging with photo-voltaic self-consumption. To assure this form of "solar charging" , the installation must have the necessary units to allow efficient and optimal management of the available renewable energy from the viewpoint of both generation and consumption.

The power control and demand management units will intelligently charge the EV, giving priority at all times to photovoltaic energy, guaranteeing the energy supply, as follows:

Directly from the sun. From the distribution lines. From the customer's internal network.


EFM-PVing PARK KIT

With the PVing PARKS kits, there are two possible units to choose from for charging electric vehicles:

RVE2 charge posts have been designed to cover the charging needs of electric vehicles that support quick battery charging while complying with all the features of mode 3, in accordance with the IEC 61851-1 standard, as well as with the features of mode 1, electrical and safety standards for accessing, measuring and managing consumption. These charging points are especially recommended for all outdoor locations that may be used for any type of vehicle parking (cars, motorbikes, bicycles, transport, cleaning, etc.).

Figure 10: RVE2

Wall-Boxes, vehicle charging boxes from the RVE family, have been designed to facilitate electric vehicle charging in indoor car parks, in compliance with electrical safety regulations and in relation to access, measurement and management of consumption. These units have type I, type II and Schuko connections and enable charging in mode I (Schuko) and mode 3 (IEC-61851-1).

3�- KIT INSTALLATION

3.1.- PRELIMINARY RECOMMENDATIONS

This manual contains information and warnings that users must follow in order to guarantee the safe operation of the system, keeping it in a generally safe condition.

In order to use the unit safely, it is essential that the individuals who handle it fol-low the safety measures set out in the standards of the country where it is being used, use the necessary personal protective equipment, and heed the various warnings indicated in this instruction manual.

EFM-PVing PARK self-consumption kits must be installed by authorised and qualified person-nel.

To install PVing PARKS you firstly need a technical project and the building licence/construction permit from the relevant competent authority of each area.

The power supply plug must be disconnected before handling, altering the connections of or replacing any unit. It is dangerous to handle the units while they are powered.

Also, it is essential to keep the cables in perfect condition to avoid accidents, personal injury and damage to installations.

The manufacturer of the unit is not responsible for any damage resulting from failure by the user or installer to observe the warnings and/or recommendations set out in this manual and in the manuals from the various manufacturers of the elements included in the kit, nor for damage resulting from the use of non-original products or accessories or those made by other manu-facturers.

If an anomaly or malfunction is detected in any component of the kit, do not handle any of the elements and contact a qualified technical service representative.

Disconnect the units from all power supply sources before undertaking any main-tenance work, repairs or manipulating their connections. Contact the after-sales service if you suspect that there is an operational fault in any element of the kit.

Take into account that when the units are connected, the terminals may be haz-ardous to the touch and opening the covers or removing elements may expose dangerous parts. Do not use the units until they are fully installed.


EFM-PVing PARK KIT

All the electrical circuits must be equipped with their proper protection.

3.2.- INSTALLATION

3�2�1�- INSTALLATION OF THE STRUCTURES

The mechanical structures are the first element of the kit to be installed. These structures will normally be installed on compact and level ground to prevent unwanted mechanical stresses. The materials sent to assemble a structure are specific to each installation and must be defined beforehand by the user and CIRCUTOR.

CIRCUTOR does not carry out studies or engineering projects for installing struc-tures; it merely provides the appropriate material for assembling the photovoltaic modules in each EFM-PVing PARK kit after the customer selects the assembly setup they wish to install.

CIRCUTOR is not responsible for selecting or assembling the structure.

CIRCUTOR sends a document with the list of materials to be provided so that users can con-firm the shipment and have full knowledge of the materials they will receive.

For each of these structures, CIRCUTOR provides a general assembly manual so that the installer has a generic guide to all the parts of the structure and what they are used for.

Naturally, being generic manuals, they do not specify the exact number of modules to use (as this varies according to the EFM-PVing PARK) kit, but they do include generic guidelines to follow for installation.

3�2�2�- INSTALLATION OF THE CONCRETE FOOTINGS

In order to use the units safely, it is essential that the individuals who handle them follow the safety measures set out in the standards of the country where it is being used, use the necessary personal protective equipment, and heed the various warnings indicated in this instruction manual.

Dig trenches for concrete footings with the following approximate measurements: 1000x1000x1000 mm (length x width x height)

Figure 12:Dimensions of trenches for concrete footings

The distance between trenches depends on the number of parking spaces that there are be-tween them; those distances are indicated below:

Table 3:Distance between trenches�

Figure 13:Distance between trenches


EFM-PVing PARK KIT

Next, dig a trench to pass the electric wiring from the canopy to the building and the earth wire. This trench should only be dug in the foot where the String Box and the charging point for the electric vehicle are to be installed (installed on the same foot; look at mechanical diagrams that specify in which feet these elements will be installed).

Figure 14: Trench for wiring�

If the earth wire and the area where the AC protection box (Combiner Box) and the inverters will go are in opposite directions, you can dig two separate ditches in the required direction.

Assemble the formwork with the rods and busbars, using the DIN934 screws and DIN125 washers.

The dimensions of the formwork structures vary according to the PVing PARK type (MP2 or MP4). The assembly is the same in each case; only the distances between elements vary (specified below)

Figure 15: Template assembly

The formwork dimensions for single canopies (MP2) are as indicated in the image below:

22

EFM-PVing PARK KIT

Installation Guide

Figure 16: Dimensions and formwork elements for PVing PARK MP2

The formwork dimensions for double canopies (MP4) are as indicated in the image below:

Figure 17: Dimensions and formwork elements for PVing PARK MP4

The placement of the formwork structures and footings is a critical step in as-sembling the structure. An error of just a few millimetres between footings may lead to a far greater deviation at the top of the strut, and potentially affect the placement of the beams.

After completing the trenches, place the formwork structures inside. The formwork will be no higher than ground level. The distance between formwork structures will be that specified above according to the number of parking spaces between the trenches.


EFM-PVing PARK KIT

Figure 18: Placement of formwork in footing�

After installing the formwork in perfect position, connect the conduits with the earth wire wiring and the DC, AC and communications wiring to the inverter room.

Figure 19: Placement of formwork in footing�

Then refill the wiring trenches.

Figure 20: Trench with wiring�

24

EFM-PVing PARK KIT

Installation Guide

Refill the M60 type concrete footing up to a height of approximately 500 mm, leaving the form-work structures submerged approximately 150 mm from the bottom of the trench. These meas-urements are calculated so that once the footing is finished, the dowels overhang 50 mm.

Figure 21: Trench with concrete and wiring�

Leave the concrete to harden for 24 h.

After it has hardened, remove the formwork structures from the footings.

Figure 22: Trenches without formwork structures�

To finish the assembly of the footing, insert a DIN934 M24 screw and DIN125 M24 washer in each rod. These will be the pieces where the feet of the canopy will be placed and supported.


EFM-PVing PARK KIT

Figure 23: Placement of support screws�

3�2�3�- INSTALLATION OF THE FEET

To lift and place the foot more easily, we recommend that you pass cords or similar through the holes of the foot indicated in Figure 24, using screw pins and a forklift, crane or similar (weigh-ing 200 Kg. approx.).

Figure 24: Fastening of the feet for elevation�

Then raise the foot and place it in the footing as shown in Figure 25 passing the holes of the foot through the rods of the formwork.

There are three types of foot: start, middle and end. Place each type of foot in the corresponding trench.

26

EFM-PVing PARK KIT

Installation Guide

Figure 25: Placement of the feet�

In the trench with the wiring conduits, they must pass through the interior of the foot of the canopy to two points:

Figure 26: Foot wiring�


EFM-PVing PARK KIT

Figure 27: Foot wiring�

Once the foot is in position, remove the screw pins used to pass the cord.

Then level the foot of the canopy. For this, you will need to change the position of the lower support screws (those below the feet) until the base is totally level.

It is very important to level the footings and the feet. Incorrect levelling at the base of the structure may cause excessive stresses in the beams.

After levelling the feet, refill the footing with concrete until the foot is flushed and leave to hard-en. After finishing, the rods should have a 50 mm dowel from the surface of the footing.

28

3�2�4�- INSTALLATION OF THE STRUT

To lift and place the strut easily, we recommend that you pass cords or similar through the holes of the strut indicated, using a forklift, crane or similar (weighing 200 kg approx.), as indicated in Figure 29.

Figure 29: Attachment of the strut�

Align the holes of the strut with the holes of the foot, attaching it with the DIN603 M20x120mm screws and the DIN6923 M20 washers. Once positioned, remove the cord or similar.

3�2�6�- INSTALLATION OF THE PHOTOVOLTAIC MODULES

Once the structure is installed, the photovoltaic modules should then be installed. Their instal-lation can be divided into 2 parts:

1�- Mechanical installation (attaching the modules to the structure) (3.2.6.1.- MECHA- NICAL INSTALLATION)

2�- Electrical installation (connecting the positive and negative terminals)(3.2.6.2.- ELEC-TRICAL INSTALLATION)

3�2�6�1�- MECHANICAL INSTALLATION

The modules are attached to the structure using snap clamps. Before tightening them, check that the structure supports the modules on a flat plane to avoid torsional moments that could generate mechanical stresses in the modules. The process for attaching the modules is de-tailed below:

CONNECTIONS BETWEEN MODULES

The photovoltaic modules are equipped with a connection box in the back with two cables with MC-4 type connectors, one with positive polarity and one with negative polarity.

Figure 44:Rear connection box of the photovoltaic module

Use the modules' own cables only to connect each element of the series or strings to each other, following the pattern (first module's negative connected to the second module's positive and so on).

With the PVing PARK solution, MC4 connectors (male and female) are provided for making the extensions in those modules in which the required configuration is not possible with the cable of the photovoltaic module. CIRCUTOR supplies the connectors but not the electrical cable which


EFM-PVing PARK KIT

must be provided by the installer. We recommend that you use the FLEX-SOL-XL 4 mm2 or similar cable suitable for DC installations.

WARNING: All PVing PARK kits already have the electrical configuration of the modules determined (number of modules in series and number of photovoltaic strings). Look at the diagrams supplied with the canopy for the correct configura-tion procedure.

Each series of modules will end up with one cable with a positive connector and one with a negative connector at each end.

Figure 45:Serial connection between photovoltaic modules

WARNING: All the strings that will subsequently be connected in parallel must have the same number of modules, otherwise their voltages will not match up and the strings with more modules will supply power to those with fewer mod-ules, causing serious damage, power losses and a reduction in the useful life of the modules.

CONNECTION OF THE STRINGS

Based on the number of strings in the module connections and the number of DC inputs in the inverters that come with the kit, it may be necessary to group strings together in parallel before connecting to the inverters' connection panel.

To connect two or three strings in parallel we recommend using the branch connectors avail-able on the market, as they create connections that are very safe and durable (remember that a string of modules can have very high DC voltages)

Figure 46:Strings connection

Figure 47:Parallel connection of 2 strings of photovoltaic modules

The wiring selected to transport the energy produced by the modules to the inverters' connec-tion panel must be calculated based on the intensity of the total current, the number of strings connected in parallel and the distance to the panel in order to avoid a voltage drop of over 3%. The REBT low-voltage regulations and applicable technical instructions shall be complied with at all times, in terms of voltage drop and thermal criteria.

INSTALLATION OF ELECTRIC PANELS

The PVing PARKS range of kits includes the electric panels of the DC part (String Box) and the electric panels of the alternating part (Combiner Box), specific for each kit.

The installation of the DC circuit involves connecting the photovoltaic modules to the photovol-taic inverter's DC input. For this, use the String Box which includes all the necessary protec-tions (fuses and overvoltage protection) to ensure the correct protection of the DC circuit.

Install the String Box at the bottom of each of the struts of the canopy as shown in the figure below:


EFM-PVing PARK KIT

Figure 48: Installation of the String Box

To attach the String Box, drill four holes in the strut of the canopy, preferably in the area shown in Figure 48. Depending on the type of PVing PARK acquired, the size and weight of the panel may vary, so it is up to the project manager or installer to decide on the attachment system to use.

In the diagrams delivered with the canopy you can see the configuration of the photovoltaic strings as well as the terminals where they will be connected.

The Combiner Box is the electric panel containing all the protections of the alternating part, as well as the control elements (CDP) and power analyzer if the installation requires it.

We recommend that you install this panel in the same area where the inverter will be installed and, if possible, near the general switchboard of the building

The panel comes fully wired so the user will only have to connect the terminal strips of the panel as shown in the diagrams supplied with each canopy.

3�2�7�- INSTALLATION OF THE INVERTERS

Each PVing PARKS kit comes with the appropriate inverters for the connection system (single-phase / three-phase), power (kW) and number in order to achieve a photovoltaic self-consump-tion installation with 0 injection of the specified power.

The inverters provided come with a specific user manual that must be consulted before and during installation. It is obligatory to follow all the installation conditions indicated in the manuals for each model so that the installation will have all operating guarantees.

All the inverters have at least one positive terminal and one negative terminal, to which you must connect the cables from the photovoltaic modules or from the respective String Boxes.

The inverter installation is divided into the following 4 points (detailed in the corresponding in-verter manual which we recommend reading prior to installation):

1�- Mechanical anchoring to the wall (see the specific inverter manual)

RVE-WB-MIX-CP1

In order to use the unit safely, it is essential that individuals who handle it follow the safety measures set out in the standards of the country where it is being used, use the necessary personal protective equipment, and heed the various warnings indicated in the RVE-WB-MIX-CP1 instruction manual.

The RVE-WB-MIX-CP1 is a unit designed to be secured to the foot of the canopy and has 4 points for its attachment, as shown in the figure below.

Figure 50: Wall Box installation


EFM-PVing PARK KIT

The electrical installation must be carried out by qualified professionals, with a project or not depending on the power installed.

This unit is 230 VAC single phase, and is designed for use in 400 V/230 VAC THREE-PHASE OR SINGLE-PHASE networks of ±10%.

There is an earth terminal which must be properly wired to the protection conduc-tor with a minimum cross-section of 6 mm2. Its correct connection and dimensioning is very important.

The conductors will have a minimum cross-section of 6 mm2, but may be more depend-ing on the installation conditions (length, ducts, etc.). The authorised installer is responsible for designing and performing the installation.

The unit can communicate via RS-485 with compatible appliances to form part of a more com-plex network, and therefore be able to send and receive orders or information.

Figure 51: Internal communication terminals of the WB�

The RS-485 network must be installed according to the requirements indicated in its standard, IEC 60364-4-41, including linear topology, line termination resistances, shielding, equipotentiality of masses, etc.

In all cases, it must be ensured that the end user is protected against indirect contacts by means of a residual voltage relay (DDR or differences) with sensitivity of 30 mA.

We recommend consulting the product manual for the correct electrical installa-tion of the unit.
