3. General Safety Advice

Please ensure all necessary measures are taken to prevent accidents. The use of SolarSets in applications that may endanger human lives is prohibited, including in air and road transport systems. SolarSets must not be used for anything other than their expressed purpose. Solar Frontier strongly advises you to follow the instructions below in order to avoid bodily injury, damage to property and/or death.

SolarSets sold by Solar Frontier GmbH may only be installed by authorized professionals (see 6.2). As soon as it becomes evident that safe operation is no longer possible (e.g. visible damage), remove the SolarSet immediately from the grid.

3.1 Safety advice for photovoltaic modules of type Solar Frontier SF170-S

• Installation, wiring, and maintenance of SF modules must only be carried out by licensed and trained persons.

• Ensure that all instructions and information related to SF modules and other balance of system components are fully understood prior to handling and installing a PV solar system.

• The front surface of SF modules should be covered with an opaque material during installation to decrease the potential of electri- cal shock.

• SF modules only generate direct current (DC) electricity.

• SF modules do not have the ability to store electricity.

• SF modules will experience higher voltage when connected in series and higher electrical current when connected in parallel.

• Only interconnect SF modules with similar electrical characteristics in series or in parallel to prevent system imbalance conditions and module damage.

• The PV array open-circuit voltage must never exceed the maximum system voltage (including in low temperature conditions).

• Leakage currents could create a shock hazard or re.

• Do not disconnect operational modules or electrical arcing may occur. This may result in serious bodily harm or death.

• Do not use SF modules for purposes other than terrestrial power generation to prevent electrical shock, re or other accidents.

• Do not articially concentrate sunlight on modules using lenses or mirrors.

• Do not use light sources other than natural sunlight and general illumination for power generation.

• Do not use SF modules in water or liquid. There is a serious risk of electric shock, an electric leak or an accident.

• The level of leakage current must be limited in accordance with local regulations for safety reasons.

• Carefully check the polarity of the wiring before installing. Incorrect wiring may damage SF modules or appliances.

8. Installation

For a safe installation, all relevant national and local laws, regulations and directives, especially for accident avoidance,

as well as all relevant technical standards are to be adhered to.

8.1 Mounting system/ substructure

The SolarSets are delivered without mounting systems. In general, all mounting systems commercially available, are suitable (e.g. Novotegra (MHH), HatiCon, K2 Mounting Systems, Easy Roof (IRFTS), Schletter, Tritec) provided that the installation is in accordance with the requirements indicated in 8.2.3. Your installer will be able to suggest a suitable solution.

8.2 Mechanical installation of Solar Frontier SF170-S photovoltaic modules

8.2.1 Site location

• Ensure that the maximum wind and snow loads in local conditions do not exceed the SF module maximum load ratings.

• Avoid installing SF modules in areas where they are exposed to oil vapour and /or corrosive gas.

• Avoid accumulation of grit or dust on the SF modules as it may inuence the output yield.

• Do not expose SF modules to sulphurous atmospheres.

• Do not install SF modules in locations where ammable gases accumulate or ow as there is a risk of sparks from SF PV modules.

• Do not install SF modules near re.

• Avoid installing SF modules in locations where they may be covered by permanent shadows. This may adversely aect their perfor- mance.

• Do not install SF modules in locations where temperatures exceed the temperature range indicated in the module’s technical specications

8.2.2 Module handling instructions

• Do not disassemble or modify SF modules. This may result in an electric shock, re or other accidents. Solar Frontier cannot be held responsible for any loss or damage caused by unauthorized disassembling, modication or misuse of SF modules.

• Do not drill additional mounting holes into the aluminum frame. Only pre-drilled holes should be used.

• Avoid placing any stress onto the SF modules, cables or connectors. (Minimum bending radius of 39 mm for module cables is recommended)

• Do not stand or step on SF modules. This may result in damage to the module and/ or bodily harm by falling.

• Do not drop SF modules or drop objects onto them. Both sides of the module (the glass surface and the back sheet) are fragile.

• Do not strike the terminal box or pull the cables. The terminal box can crack and break, while the output cable may unplug and cause electricity leakage or an electric shock.

• Do not scratch the back sheet or cables of the SF modules. Rubbing or scratching may result in an electric shock, electric leakage or an accident.

• Do not scratch the insulation coating of the frame (except for the grounding connection). This may weaken the strength of the frame or cause corrosion.

• Do not cover the water drain holes of the frame. Doing so may cause frost damage.

• Do not use glue when closing the cover of the junction box. Similarly, do not use a sealant to bond the junction box lid to its base.

Page 13

8.2.3 Module mounting instructions

Mounting structures cautions

• Pay attention to the electrochemical series when selecting support structure material to avoid galvanic corrosion.

• Fasten and lock bolts completely. Inadequate mounting may result in SF modules falling or other accidents.

• Ensure that the SF modules are securely fastened to the mounting support structure that is durable, made of UV and corrosion resistant material, and follow the applicable local and civil codes.

• Ensure that your mounting support structure is designed to withstand the SF module design snow and wind loads applicable for the chosen site. Solar Frontier will not be responsible if the SF modules are damaged due to the durability of the mounting support structure. Please consult your mounting structure manufacturer.

Mounting the solar modules

• PV modules should typically face South in the Northern Hemisphere and North in the Southern Hemisphere for optimal power production.

• Modules can be installed horizontally (landscape) or vertically (portrait).

• Maintain a space between SF modules and the roof. This will allow air to circulate, cooling the module, and allowing condensation to dissipate. Solar Frontier recommends a distance of at least 100 mm (3.94 in).

Mounting with Screws

SF modules should be fastened to the support structure using the mounting holes on the frame. The support structure should be securely fastened to a non-corrosive roof. Tighten the screws with an adequate torque value. Please refer to further instructions and adequate torque value provided by the screw manufacturer.

Mounting with Inner Holes

Each module will require four M6 (or 1/4 in) bolts with washers, lock washers and nuts. Tighten the screws with an adequate torque value.

UL: Recommended tightening torque is 8 Nm (70.8 lb in) minimum.

8.3 Electrical Installation photovoltaic generator

8.3.1 Electrical wiring safety precautions

• The sum of Voc of modules in series must not exceed the maximum system voltage of the module under any condition. Reverse current applied to the modules must not exceed 7 A.

• Do not touch or handle the PV module, terminal box or the end of output cables with bare hands.

• Do not carry out installation when PV modules, installation tools or installation area are exposed to water.

• Ensure that the connection parts between SF modules and power receiving devices are isolated and waterproof. Using SF modules with insucient isolation and waterproong could result in an electric shock, an electric leak or an accident.

• Keep the wiring box (junction box) and the module connector away from any liquids until connectors are mated. Failure to do this may cause faulty wiring.

• Components interconnecting the modules must be compatible with the connectors, and must provide system operation and fault protection.

• Inverters must meet the technical requirements of SF modules.

• Do not connect the PV modules directly to loads such as motors. Variation in output power may damage the motor.

• Observe and understand the safety instructions of batteries. Their misuse can result in serious bodily harm due to high electrical current.

• Cables should be adequately protected from damage by wildlife

8.3.2 Cabling

Solar Frontier places great value on delivering as many components as possible pre-assembled in order to help avoid sources of error. Since roof and PV installation has its own specialities, it may be necessary to adapt certain cables on site to t them best (e.g.: connections cables to the inverter shall be cut and assembles on site, and/or extension cable will be necessary to wire around interrupted strings on the roof of obstacles exist such as chimneys). The DC-cable, sockets and plugs which are included in the SolarSet are for this purpos. A suitable crimping tool is necessary but excluded of the SolarSet).

Please ensure a clean and proper assembly of the cables to avoid error sources and to ensure safe cabling.

To assemble the cables the following tools are necessary:

- Mounting key (not scope of the delivery)

- Crimping tool for twisted contacts (not scope of the delivery)

- Insulation stripping pliers (not scope of the delivery)

Shortening and stripping the insulation from cables

First, the cable has to be shortened to the proper length. Then the outer insulation is removed with a suitable insulation stripping pliers to a length of 7 mm.

Ensure that the wires are not damaged – a reduction of the cross-sectional area can result in electrical errors.

Page 18

See Figures 12 and 13:

Crimping the twisted contacts

Push the stripped end of the cable into the crimp sleeve as shown in Figure 14 Make sure that all wires are inside the crimp sleeve. The wires must be visible in the small opening.

To crimp the sleeves use the „hex“ or „4-ident“ crimp die. Put the crimp sleeve with the cable in the respective slot on the crimp pliers. The crimping tool must be suitable for drilled crimp contacts of the type Amphenol Helios H4. For more detailed information on using the crimp pliers please consult the operations manual of the pliers manufacturer.

See Figures 15 and 16:

Checking the crimping results

A visual check of the crimping results, and a pull test are needed to ensure a correct crimping. Figure 17 and Figure 19 show a good result for a „hex“ crimping; Figure 18 and Figure 20 show a good result for a „4-ident“ crimping:

The pull test should be for at least 310 Newton.

8.3.3 Procedures for electric cabling

The electrical cabling of Solar Frontier SolarSets has to be done as described in Chapter 7, Table 2. Take care that the exact number of modules in series are connected in accordance with Table 2, and that the respective number of parallel strings is adhered to.

String connection

The serial connection of modules should be done in accordance with 8.3.5, Figure 31 and 32.

Procedure by interrupted strings:

If it isn’t possible to connect modules directly, the plugs, sockets and DC-cable provided can be used to bridge gaps.

An exemplary approach is shown in 8.3.5, Figure 33 and 34. The basics on assembling an extension cable can be found in Chapter 8.3.2 Assembly. Please note that only a limited number of plugs/sockets are provided in the set, and that the cable provided is primarily for the extension from the generator to the inverter.

If you should need extra material, please ensure that the compatibility to the SolarSet products is conrmed. If in doubt please contact Solar Frontier.

Connecting the strings

The string connecting cable in the set is used to connect the strings and lead them to a mutual collection point. The number of strings can be determined in Chapter 7, Table 2.

DC-cable

The DC-cable is used to extend the connecting cables in the PV generator with the inverter. Basics on assembling the cable can be found in chapter 8.3.2

Connecting to the inverter

The connection of the PV generator to the inverter is described in detail in chapter 8.4. Please ensure that the instructions and procedures described there are strictly adhered to to avoid possible danger sources and to ensure a safe installation.

8.3.4 Grounding

Grounding cautions

• Be aware of the necessary grounding requirements prior to installation. Your local authorities can help you further.

• Install arrestors, surge absorbers or any other appropriate lightning protection tools as needed.

• Module frames, mountings, connection boxes and metal conduits should be connected to an earth ground as lightning protection, in accordance with local, regional and national standards and regulations.

• Grounding holes (ф 4 mm) on the aluminum frame of the SF modules are provided to accommodate grounding. Use a grounding wire made of copper, not smaller than 2 mm² (14AWG). Temperature rating of the conductors must be between -40 °C to 85 °C. Ensure that the crimping terminal is tightly tied to the module frame with a rolling thread screw and a lock washer to ensure electrical contact.

• Grounding devices such as module clamps with an integrated grounding pin, serrated washers, grounding clips or lugs, designed for bonding photovoltaic modules to the mounting structures may also be used for grounding as described in NEC section 250. These grounding devices shall be made in conformance with the grounding device manufacturer instructions. Consult the grounding device manufacturer to identify the appropriate grounding and bonding device for your mounting structure or design.

For alternative grounding methods please consult Solar Frontier.

UL: The module with exposed conductive parts is considered to be in compliance with UL 1703 only when it is electrically grounded in accordance with the instruction presented below and the requirements of the NEC.

Reactive power characteristic curve - Overview

The reactive power characteristic curve must be set during initial commissioning if this is prescribed for the previously selected country. The following applies:

• 3 characteristic curves are available for selection (see left):

- Default. char. curve (pre-dened)

- Char. curve cos φ = 1 (pre-dened)

- Enter char. curve (manually adjustable)

• After conguration, the characteristic curve is diplayed as a graph (example left).

x-axis, output power P in%

y-axis, phase shift cos φ

nodes (in example: 4 nodes)

arrow symbol overexcitation

arrow symbol underexcitation

Page 40

Technical details

• Each characteristic curve is dened by 2 to 8 nodes.

• A node is dened by the output power of the inverter (x-axis) and the associated phase shift (y-axis).

• The phase shift can be set over a range of 0.95 (overexcitati- on) through 1.00 (no phase shift) to 0.95 (under excitation)

• The type of phase shift is shown in the graph using arrow symbols dened as follows (dened from the point of view of the inverter:

Overexcitation - inductive Underexcitation - capacitive

• The 3 characteristic curves available for selection have the following properties: Default char. curve: pre-dened according to the selected country (example left) Char. curve cos φ = 1: pre-dened with cosφ = constantly 1.00. this characteristic curve must be selected if no reactive power control is to be performed on the device. Enter char. curve: the number of nodes and their x/y values can be congured. Exceptions: the rst node is always located at x(P%)= 0% and the last node is always located at x(P%) = 100%.

9.4 Cooling

The internal temperature control system prevents excessive operating temperatures. When the internal temperature is too high, the inverter adjusts the power consumption from the solar modules to reduce the heat dissipation and operating temperature. The inverter is convection-cooled via ns on the front and rear side. A maintenance-free fan circulates the heat within the closed casing evenly over the entire surface of the casing.

9.5 Grid monitoring

The inverter constantly monitors the mains grid parameters while feeding the grid. If the grid deviates from the legally prescribed specications then the inverter automatically switches o. When the grid conforms to the legally prescribed specications then the inverter automatically switches on again. The legally prescribed specications for the grid parameters are described in the Table of countries,in chapter 15.4.

9.5.1 Data communication

The device has the following communication interfaces:

• 1x RJ45 socket (Ethernet for TCP/IP network) for communication, e. g. with a central data server

• 2x RJ45 sockets (RS485 bus) for communication with external devices, e. g. a data logger

Data

The inverter can transmit a wide range of data to other devices. Some of this data is shown on thedisplay and certain data is stored in the internal memory (EEPROM) as described below.

Network (TCP/IP)

The device can transfer yield data and event messages via the TCP/IP interface to the Internet portalserver at http://www.solare-energiewende.de. The yield data can be displayed graphically in theInternet portal as illustrated below. This service is free of charge for 2 years. The following applies:

• The user must rst register at www.steca.com/portal before the Inter- net portal can be used.

• The local network settings must be set at the inverter in order to esta- blish a connection to theInternet portal server. This can be performed automatically or manually: Automatically: If IP addresses are automatically assigned in your network (DHCP), then no settings need to be made at the inverter. Manually: If IP addresses are not automatically assigned in your network, then you must manually set the inverter network settings via Settings > Network, P. 37

• The address of the Internet portal server is permanently stored in the inverter and cannot bechanged.

• Once the network connection is established, the inverter automati- cally starts non-encrypted transmission of data to the server.

Notice

The network cable must be disconnected in order to prevent transmission of the data.

Page 42

RS485-Bus

The inverter communicates with other devices via an RS485 bus. The following applies:

• The inverter has two RS485 interfaces (RJ45 sockets) on the lower side of the casing.

• The beginning and end of the RS485 bus must be terminated; see P. 43.

• Standard RJ45 cables can be used as bus cables (Cat-5 patch cables, not supplied). Use an alternative data connection cable for longer connections; see P. 43.

• The inverters connected to the RS485 bus operate as bus slave units.

Notice

The SF-WR has a compatible data interface and can be connected to the RS485 bus as slave.

• If one of the optionally available devices below is connected to the bus, then this device operates as a bus master.

• Only 1 master may be connected to the RS485 bus at any given time.

The following optional available devices support the transfer protocol used by the inverter.

• StecaGrid Vision remote display: display of the data from inverters connected to the RS485 bus.

• Energy management unit StecaGrid SEM

• PC or notebook (with suitable software, for technical professionals only): – Load rmware updates – Read inverter information using service software – An optional RS485nUSB adapter for connecting to the inverter is also available. Theadapter is available from Steca.

• External data loggers, for professional system monitoring: – WEB‘log (Meteocontrol) – Solar-Log (Solare Datensysteme)

Note

The correct settings must be made in external data loggers, according to the manufacturer‘sinstructions, before connecting them to the bus.

The wiring diagram of the RS485 bus is shown below.

ATTENTION!

Material damage caused by electrical voltage! The alternative data connection cable may onlybe manufactured by technical professionals.

The alternative data connection cable is a Cat-5 cable for long data connections. The followingapplies to the alternative data connection cable

• The total length of the RS485 bus must not exceed 1,000 m (master/rst inverter to lastinverter)

• Use a 1:1 pin assignment if the alternative data connection cable is connected to the RJ45sockets of the inverters and the data logger

Page 43

• Use the pin assignment according to the table below if the alternative data connection cable isconnected to the RJ45 socket of the rst inverter and to the connector of the data logger.

Plugs for the alternative data cable are included in the scope of delivery for the StecaGrid Vision.More information is provided in the

StecaGrid Vision manual.

ATTENTION!

Danger of destroying the RS485 input of the inverter. Pin 1 of the RJ12 socket of the Web‘logdata logger carries 24 V DC. Never connect the alternative data connection cable to pin 1!

Termination

To prevent data transmission errors, the start and end of the RS485 bus should be terminated:

• The StecaGrid Vision (at the start of the data connection) is permanently terminated internally.

• The external data logger (at the start of the data connection) must be terminated according tothe manufacturer‘s specications.

• The last inverter (at the end of the data connection) is terminated by plugging the optionallyavailable termination plug into the free RJ45 socket (for RS485 bus).

Adressing

• Every inverter must be assigned its own unique address for communication between the bus masterand the slaves.Every inverter is set with an address of 1 at the factory. This means that the addresses must beadjusted in systems having more than 1 inverter. The following applies:

• The address is changed at the inverter via the menu items Settings > Adress .

• Only addresses ranging from 1 – 99 may be set.

• The bus master devices usually support less than 99 addresses. Consult the respective operatinginstructions for these devices before setting the addresses of the inverters.

• We recommend starting with address 1 for the rst inverter on the bus and then incrementingthe address by 1 for each subse- quent inverter on the bus, in the same order as they are physically installed. This makes it easier to identify the relevant inverters when their address is displayed in messages shown on the remote display.

Feed-in management

Depending on the country, the active power fed into the grid by a photovoltaic system must be ableto be reduced by the grid operator. The following products are recommended for implementing thislegally prescribed specication::

• StecaGrid SEM

• WEB’log from Meteocontrol

• Solar-Log from Solare Datensysteme

9.7 Self test

The self test is mandatory for operation of inverters in Italy.

Function

The prerequisites for performing the self test are as follows:

• The country Italy was selected during initial commissioning.

• The level of solar irradiation is high enough to ensure that the inverter can feed the grid.

During the self test, the inverter checks its switch-o behaviour with regard to too high / too low grid voltage and frequency (5 test phases, duration of approx. 35 minutes). The following applies:

• In each phase of the self test, the inverter changes its switch-o threshold, step-by-step upwards/downwards from the set lower/ upper limit values.

• When the switch-o threshold reaches the actual grid voltage/frequency then the inverter stores this information.

• The data is shown on the display as follows:

- The current values of the rst test phase are displayed rst; see Figure 49.

- The values of the subsequent test phases are added below (initially hidden)

- If the self test succeeded then the message Self test passed is added below. The message must be displayed and conrmed.

• If the self test conditions are not satised, one of the messages listed in Table 5 is displayed.

• If a measurement lies outside the required tolerance during the self test then the self test is cancelled and the inverter displays the message Self test failed. The inverter remains disconnectedfrom the grid (relay open, no feeding) until the self test is passed successfully.

11. Maintenance

11.1 Maintenance Solar Frontier SF170-S photovoltaic module

A monthly visual check is highly recommended in order to maintain the eciency of SF modules and the security of the mounting.

• Remove any dirt, fallen leaves or bird droppings from the surface, and check that there is no damage to the surface. Do not use detergent or chemicals for cleaning dirt o SF modules as it may damage the modules and result in degradation of insulation.

• Do not use hard brushes or any other hard materials; use only soft cloths or sponges for removing dirt from the SF modules surface.

• When replacement parts are required, be sure the installer/servicer uses parts specied by the manufacturer with the same charac- teristics as the original parts. Unauthorized substitutions may result in re, electric shock, or other hazard.

• Stop using SF modules when any damage or unusual phenomena are observed. Have them immediately replaced or removed by a qualied technician.

11. 2 Maintenance DC-system

The DC-system is maintenance-free. It is still recommended that cables and connectors are regularly checked for signs of damage.

11. 3 Maintenance inverter SF-WR

The inverter is practically maintenance-free. It is still recommended that the cooling ribs on the front and back of the device are regularly checked to make sure that they are dust-free. If necessary, clean the device as described below.

Note

Danger to life through electrocution. Apply cleaning agents using only lightly moistened cleaning cloths.

• Cleaning agents and machines should not be allowed to penetrate between the cooling ribs (under the black hood) on the front side of the inverter.

• Do not use any of the following cleaning agents:

- Cleaning agents containing solvents

- Disinfectants

- Gritty, hard, scouring, or sharp cleaning materials

Removing dust

 We recommend removing dust with air pressure (max. 2 bar)

Danger

Danger to life through electrocution. Apply cleaning agents using only lightly moistened cleaning cloths.

Getting rid of more severe dirt

 More severe dirt can be removed using a lightly moistened cloth (use only clear water). If necessary use a 2% solution of curd soap. After completing cleaning remove remains of soap with a lightly moistened cloth.

Power tolerance +5 W / 0 W Open circuit voltage Voc 112 V Short circuit current Isc 2.20 A Voltage at nominal power Vmpp 87.5 V Current at nominal power Impp 1.95 A

Photovoltaic modules may produce more current and/or voltage under actual operating conditions than in Standard Test Conditions. The electrical characteristics are within 10 % of the indicated Isc and Voc values under STC. The power output stated on the label is measured at the plant after module preconditioning. The values of Isc and Voc marked on modules should be multiplied by a factor of

1.25 to determine component voltage ratings, conductor ampacities, overcurrent device ratings and size of controls connected to the module output. UL: Refer to section 690.8 of the National Electrical Code for an additional multiplying factor of 125 % (80 % derating). Installation must be completed in accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.

15.1.2 Certicates for Solar Frontier SF170-S

Solar Frontier’s CIS thin-lm modules are not only tested under extreme conditions, such as heat, cold and high stress tests, in our own research center, the Atsugi Research Center (ARC). Independent institutions, such as TÜV or Atlas 25+, conrm the long-term yield capabilities of our modules on the basis of accelerated aging tests. Regional certications are limited to the respective business locations of Solar Frontier. These include the dependencies in Japan, Europe, North America and Saudi Arabia, our three production sites and the Atsugi Research Center in Japan.
