2.0 Safety precautions

WARNING: Please read and understand all safety instructions

before installing, wiring, operating, or maintaining modules.

DC power is generated when the module is exposed to

sunlight or other light sources. Direct contact with live parts of

the module, such as terminals, whether connected or not, may

result in personal injury or death.

Safety rules.

• All installation work must be in full compliance with local regulations and corresponding national or international

electrical standards.

• Use insulated tools to reduce the risk of electric shock.

• Use appropriate protective measures (slip gloves, overalls, etc.) to avoid direct contact with workers at 30V DC or higher,

while avoiding direct contact with sharp edges during installation to protect the operator’s hands.

• Do not wear metal ornaments when installing, to avoid puncturing the modules and causing electric shock.

• If the circuit breaker and overcurrent protection circuit breaker cannot be opened, or if the inverter cannot be turned o

during the module installation or wiring, cover the array modules with opaque material to stop the power output.

• Do not use or install damaged modules.

• If the module surface is damaged or worn, direct contact with the surface of the module may result in electric shock.

• Do not attempt to repair any part of the module, there are no user-accessible components within the module.

• The cover of the junction box should remain closed at all times.

• Do not split the modules or move any part of the module.

• Do not artiﬁcially condense light on modules.

3.0 Mechanical / electrical properties

The rated electrical performance data for the modules is measured under standard test conditions (STC) of irradiance of 1000

W/m2, AM 1.5, and cell temperature of 25 °C. The speciﬁc electrical and mechanical performance parameters of Sunman eArc

modules are included in Annex A of this installation manual. The main electrical performance parameters under STC conditions

are also marked on the nameplate of each module. The maximum system voltage for all modules is 1000V.

In some cases, the current or voltage generated by the module may be greater than the optimal operating current or voltage of

its standard test condition (STC). Therefore, when determining the component rating and load value, the module open circuit

voltage and short circuit current at STC should be multiplied by 1.25. Please check with your local rules and regulation.

Storage and unpacking

• Precautions and general safety rules

• Store modules in a dry and ventilated environment.

• The modules must be transported in the package provided by Sunman and stored in the original package before

installation. Please protect the packaging from damage. Open the package according to the recommended unpacking

steps. Care must be taken during unpacking, shipping, and storage.

• Do not apply excessive loads on the modules or twist the modules.

• Do not carry the modules via the wires or junction boxes of the modules.

• Do not stand, climb, walk or jump on modules.

• Do not allow sharp objects to touch the modules. Scratches can directly aect the safety of the modules.

• Do not place the modules in an environment where there is no reliable support or is not ﬁxed.

• Do not change the wiring method of the bypass diode.

• Keep all electrical connections clean and dry.

Product identiﬁcation

• Barcode: each individual eArc has a unique serial number. The serial number has 21 digits. The 1st to 4th digits are the

module type for internal use, and 5th to 8th digits are the year code, and the 9th and 10th digits are the month code, and

the 11th and the 12th digits are the week code, and the 13th and 14th digits are the month code, and the 15th to 17th digits

are order number, and the 18th to 21st digits are the sequence codes. For example, xxxx20210415xxxxxxxxx means the

module was made in the 15th week of 2021. Each module has only one bar code. It is permanently attached to the interior

of eArc and is visible from the top front of eArc. This bar code is inserted prior to lamination.

• There is a nameplate, which shows the model number, main electrical properties, safety speciﬁcations and certiﬁcation

indicator, on the back of each module.

4.0 Installation

Precautions and general safety rules

• Before installing the modules, please contact the relevant department to obtain information about the installation site

and the construction permit, and comply with the installation and inspection requirements.

• Check the applicable building codes to ensure that the building to be installed and its structure (roof, facade, load-

bearing, etc.) has sucient load-bearing capacity.

• During installation, make sure that the modules are installed on a ﬁre-resistant roof. According to UL790 standards,

Sunman eArc modules are rated as ﬁre rating C.

• The eArc modules are compliant with application level A (equivalent to safety level II, IEC 61730-1). This type of modules

can be used in systems where the public is likely to come into contact with voltages greater than 50V or power greater

than 240W.

Environmental conditions

The modules are suitable for general climatic conditions, ie with reference to IEC 60721-2-1- Classiﬁcation of environmental

conditions Part 2-1: Environmental conditions occurring in nature - temperature and humidity.

• The modules must not be installed near ﬂames or ﬂammable objects.

• Do not expose modules to artiﬁcial condensing light sources.

• Failure to follow the above precautions may result in the Sunman Warranty being voided.

Maintenance & Cleaning

• Inspect all modules annually for safe electrical connections, sound mechanical connections, and freedom from

corrosion.

• Periodic cleaning of the modules will result in improved performance levels, especially in regions with low levels of annual

precipitation.

• To clean a module, wash its surface with potable, non-heated water. Normal water pressure is adequate. Some

ﬁngerprints, stains, or accumulations of dirt on the surface may be removed with over-the-counter cleaners (such as

Windex® or equivalent), or with a 3% soap-and-water solution. Wet the module surface with the solution, let it stand for

ﬁve minutes, and then wet them again and use a soft sponge or seamless cloth to wipe the surface in a circular motion.

Do not use harsh industrial-strength cleaning materials such as aggressive chemicals, scouring powder, steel wool,

scrapers, blades, or other sharp instruments to clean the module. Use of such materials will void the product warranty.

Installation requirements

• Ensure the modules meet the overall technical requirements of the system.

• Ensure that components of other systems do not cause damaging mechanical or electrical performance eects on the

modules.

• Connect the appropriate number of modules according to the voltage speciﬁcations of the MPPT used in the system.

Even at the lowest local temperature conditions, the connected modules must produce no more than the voltage

allowed by the system.

• In order to avoid (or reduce) the mismatch eect of the array, it is recommended to connect modules of similar electrical

performance on the same string.

• In order to reduce the risk of indirect lightning strikes, loops should be avoided when designing the system.

• The modules should be securely fastened to withstand all possible loads, including wind and snow loads.

Series & Parallel Connection requirements.

• Connect modules in series to increase voltage or in parallel to increase current. When connected in series, the positive

pole of the module is connected to the next negative pole. When connected in parallel, the positive pole of the module is

connected to the positive pole of the next module.

• The number of bypass diodes provided varies depending on the module model.

• If overcurrent protection devices (fuse) are not used in series within each string of modules, up to two strings of modules

can be connected in parallel. If a suitable overcurrent protection device is connected in series with each string of

modules, three strings or more modules can be connected in parallel.

Optimal orientation and inclination

• In order to achieve maximum annual power generation, the optimal orientation and inclination of the PV module should

be determined ﬁrst. The maximum electrical energy is typically generated when sunlight is directed onto the PV module.

Avoid shadows

• In systems with shading, it may be preferential to have multiple smaller systems with networked Victron MPPT’s.

4.1 Module wiring

Correct electrical wiring

• Check that the wiring is correct before starting the system. If the measured open circuit voltage (Voc) and short circuit

current (Isc) do not match the speciﬁcations provided, there may be a wiring fault.

Correct connection of the MC4 connector

• Make sure the MC4 connector is secure and properly connected. The MC4 connector must not be subjected to external

pressure. The MC4 connector can only be used for circuit connection functions and should not be used to turn the

circuit on and o.

• The MC4 connector should be kept dry and clean to prevent rain and moisture. Avoid direct sunlight and water soaking

of the MC4 connector.

Use appropriate materials

• Depending on local ﬁre, construction and electrical standard, use dedicated solar cables and suitable MC4 connectors

to ensure the electrical and mechanical performance of the cable.

Cable protection

• Secure the cable to the mounting system with a cable tie that is UV resistant. Appropriate measures should be taken to

protect the exposed cable from damage (eg. in a plastic sleeve with UV aging resistance). Avoid direct exposure of the

cable to direct sunlight.

4.2 Grounding

• With adhesive on the back of SMF modules, there is no metal conductor for the module or the bracket, so no grounding

of module is required.

5.0 Installation instructions

5.1 Module and tools

5.1.1 Module Handling

Applicable module models: SMF100F-3X12UW, SMF175M-4X09UW & SMF215F-4X18UW. The electrical performance

parameters are detailed in Annex A.

Use gloves when handling modules. The module is sensitive to oils and abrasive surfaces, which may lead to scratches and

irregular soiling. Do not place modules such that the module encounters abrasive surfaces and minimize any contact with the

module in general. Do not place anything on the modules, even for a moment. Never lift or move the module using the cables or

the junction box under any circumstances. Remove any ﬁngerprints by washing the module as described in the Maintenance &

cleaning Section.

Modules should be handled without excess bending or bending at sharp angles or twisting of the panels. The panels are

designed to withstand a 30-degree bend in the panel, top to bottom where the top is the side with the junction box. This is

approximately 8cm of deﬂection. Additionally, no sharp objects should be placed in contact with the panel. This can result in

puncture of the panel and/or damage to the solar cells or connectors in the panel, resulting in decreased power output and

potentially a safety hazard.

Junction boxes, cables and connectors should never be subject to a sharp or blunt force.

This can result in a broken or cracked junction box, cable, or connectors such that the panel

should not be used.

Module Mounting: The Sunman Limited Warranty for PV Modules is contingent upon modules being mounted in accordance

with the requirements described in this section.

• Site Considerations: Sunman modules should only be mounted in locations that meet the following requirements.

• Operating Temperature: All SunPower modules must only be mounted in environments that ensure they will operate

within the temperature range of -40° C to +85°C.

Care should be taken to provide ventilation behind or underneath the modules, especially

in hot environments. In cold environments of less than 0° C (32° F), care should be taken to

avoid ﬂexing of the panel or impact to the panel. Do not silicon around the perimeter of the

panels.

Sunman_RV-Marine-Flexible-Panel_Installation_Guide_2023

Module stacking and handling operations are as follows:

Unpacking precautions

Avoid operating in rainy weather when opening cartons outdoors. Secure the modules when operating outdoors in windy

conditions.

Stack components in a ventilated, rain-proof, and dry area before unpacking them.

Do not to damage the front or back of the module when using scissors or hobby knife to cut the outer packing tape.

Conﬁrm the number of modules in the box promptly after unpacking.

The unpacking area needs to ensure that the box is placed horizontally and stably to avoid tipping of the modules.

Sunman_RV-Marine-Flexible-Panel_Installation_Guide_2023

Mounting Considerations:

Modules mounted over a rooﬁng system must be mounted over a ﬁre-resistant roof covering rated for the application. To

reduce soiling, modules should be mounted at a minimum of 10 degrees.

Modules may be mounted ﬂexed

in either Longitudinal or Traverse

orientation.

The ﬂexing in the Longitudinal (width)

axis can be either convex or Concave

not both simultaneously.

The ﬂexing in the Traverse (Length) axis

can be both Convex and Concave.

The ﬂexing in all axis simultaneously

will cause undue stress on the panel

substructure causing reduced service

life.

To prevent water from entering the junction box, which could present a safety hazard, modules should be oriented with the

junction box in the uppermost position. The junction box should not be mounted in a depression when mounted on a ﬂat

surface. Note that the junction box manufacturer rates this junction box with an ingress protection rating of IP67.

Installation

In full sun applications, these panels may get up to 85°C. The expansion & contraction of both the panel and surface being

mounted to must be considered.

• Cleaning the contact surfaces: To ensure proper adhesion, all surfaces (mounting surface, back of panel and strips if

being used) must be cleaned and degreased. Not doing so will weaken the bond and can cause the bond to fail.

i. Clean the surfaces as per maintenance & Cleaning instructions above to remove excess grime/dirt.

ii. Check the surface for any loose paint or blemishes, if required rub the mounting surface with a ﬁne or medium grit

emery.

iii. Use a suitable degreasing product such as industrial alcohol or isopropyl alcohol.
