Expanding technological progress
... while remaining flexible. This drives our work and is our strategy for success. Our state-of-the-art production
facility, which is the world's largest carbon-neutral inverter factory, began operation in 2009. This raised our annual capacity to 4 gigawatt. To meet the increasing need for solar inverters, we will again more than double our
capacity in 2010. The addition of another factory in Niestetal, Germany and a new production site in Denver,
Colorado will increase our total output to 11 gigawatt. Production in our new facilities will also be flexible and
scalable. This allows us to easily keep pace with the dynamic market trends of the photovoltaic industry and at the
same time absorb short-term fluctuations in demand for solar inverters.
We also maintain our technological advantage by continuing to strengthen our development team: with more than
500 development engineers and technicians we can introduce up to 6 new products to the market each year. The
"Total Cost of Ownership", which includes issues such as energy yield, reliability, lifespan and installation costs,
play an important role in this respect. In short: our innovations provide tangible customer benefits while reducing
specific costs.
Once again, our catalogue introduces a number of new products and technologies, including the Sunny Central
CP -- a series of central inverters with a completely new design. The Sunny Central CP features a compact, weatherproof enclosure and is easier to install because it does not require a heavy concrete substation. With its intelligent power management, the device is also exceptionally efficient: at an ambient temperature of up to 25 °C, it
produces 10 percent more than the specified nominal power.
The three-phase Sunny Tripower also features the latest SMA technology, including the multi-level security concept
Optiprotect. With its asymmetric multi-string concept Optiflex, the device also offers unparalleled flexibility in the
configuration of highly efficient PV plants. The Sunny Tripower was awarded the first prize at the 25th Photovoltaic
Symposium in Staffelstein, Germany, as the most innovative product of 2010.
The Sunny Boy HF represents the new generation of galvanically isolating inverters. The Sunny Boy HF provides
the highest yields for transformer inverters in the 2 to 3 kilowatt power class, and its SMA Plug-in Grounding, Quick
Module and SUNCLIX DC connector system ensure simple and safe installation. Its compact design also makes it
ideally suited for wooden-frame houses, which makes the UL version ideal for the US solar market.
In 2010 and 2011, we will continue to make an important contribution to the future of photovoltaics with our products. For example, many SMA inverters offer comprehensive grid management functions, some of which already
exceed current statutory requirements. And we continue to look ahead to the future: for example, our development
engineers are working to create effective solutions for private solar electricity consumption, and are developing
new Smart Grid concepts.
We look forward to continuing to work with you in the future and to many successful projects.

The
Future
of
Solar
Technology
New technologies that make the worldwide deployment of photovoltaics increasingly economical. A tremendous rate of
innovation. And a unique and diverse product range. SMA Solar Technology AG has been among the most successful
companies in the field of solar technology for nearly 30 years. Our team of over 500 engineers develops state-of-the-art
solar inverters and monitoring systems for photovoltaic power-plants.
The right inverter for every application.
Since every PV plant has to be individually designed, SMA has a broad product range: we are the only manufacturer to
offer the appropriate inverter for every requirement, worldwide – whether for grid connection, off-grid supply or back-up operation. From kilowatt to megawatt, and for all module types – whether thin-film, crystalline or concentrator technology.
SMA inverters as intelligent system managers
The inverter is the most important component in any PV plant because it converts the direct current generated in photovoltaic cells into alternating current suitable for the grid. In addition, it functions as an intelligent system manager that is
responsible for yield monitoring and grid management. SMA's solar inverters are especially efficient: the Sunny Tripower
already features an efficiency of over 98 percent and thus ensures increased power production.
6
Worldwide customer proximity and international experience
SMA is the market and technology leader in the solar inverter sector, and is represented internationally by its own distribution and service subsidiaries. Our strategy: proximity to the customer in all major solar markets. SMA customers do not just
benefit from our internationally-oriented processes, but also from our many years of experience in dealing with countryspecific certification and grid compliance regulations.
SMA in figures
SMA Solar Technology AG is headquartered in Niestetal near Kassel in Germany, and is currently represented by 13
international subsidiaries on four continents. The group consists of more than 4.000 employees (including temporary staff),
and has been distinguished several times in previous years with awards for its outstanding performance as an employer.
The company has been listed in the Prime Standard segment of the Frankfurt Stock Exchange (S92) since June 27, 2008
and the company's stock has been listed on the TecDAX since September 22, 2008. In 2009, SMA posted revenues of
934 million Euros.

Einführung Wechselrichtertechnik
Solar Inverters from SMA:
The Heart of Every Solar Power Plant
The first solar inverter was one of ours. Today, SMA solar inverters are the product
of almost 30 years of experience in this
technology. With currently 7.9 gigawatt installed PV power, we play a leading role in
the success of photovoltaics. An important
reason for this is that we invest a great deal
in research and development. At our company headquarters in Niestetal, Germany,
over 500 developers are working on making the devices even more user-friendly and
more cost-effective.
Investment security
and fast amortization
Durability and economic viability are important criteria in deciding for an inverter. With
a service life of over 20 years and over 98
percent efficiency, SMA products set the
standards in this sector. The key to our success: the combination of the latest technologies and modern production processes. The
enhanced OptiTrac Global Peak operation
control, the asymmetrical Optiflex multistring topology and the Optiprotect security
concept ensure the best possible performance of the devices 24 hours a day, regardless of the weather.
Flexible plant design
Simple control
PV plants are just as individual as the buildings and surfaces on which they are installed. A broad range of products offers
the right inverter for the respective PV module and ensures best energy harvest. SMA
offers the right inverter for all requirements
making a perfect plant design possible. Our
inverters can be installed indoors as well as
outdoors.
All SMA inverters can be combined with a
wide range of components for plant monitoring: Sunny Beam with Bluetooth, Sunny
WebBox for diagnosis and maintenance
via Internet and Sunny Portal, the world's
largest online portal for the monitoring and
administration of PV plants.
Safe installation
With the SMA Grid Guard and Electronic
Solar Switch (ESS), SMA provides the most
reliable safety systems on the market. For
countries that require UL certification, the design of these safety facilities differs slightly.
(see p. 206). The standardized DC plug
system SUNCLIX, the newly developed
communication unit Quick Module or the
SMA Plug in Grounding kit make installation even easier and faster.

Plant design
Diligence that pays off
Through the skillful selection of suitable
components, a solar plant can be ideally
adapted to local operating conditions.
When designing the plant, the particularities of the chosen location must be taken
into consideration. The designing process
should therefore be conducted by an experienced specialist. The broad product
range from SMA provides a multitude of
attractive solutions, especially for this first
important step.
10
Multi-string inverter
Whenever the PV generator is exposed to
differing irradiation conditions, it should
be divided into separate strings, e.g. in the
case of varying roof pitches or some modules being in the shade. Dividing up the PV
generator in this way avoids large losses
in yield since the individual sub-generators
have different MPPs. A multi-string inverter
from SMA operates strings from PV modules
with the same level of irradiation separately
and each with its own MMP tracker thus
ensuring maximum energy yield.
Introduction to Inverter Technology
Grounding the PV generator
Some module types require a connection
to ground. Choosing an inverter with galvanic isolation (with transformer) offers
maximum flexibility here. With the appropriate grounding kit, the inverter can be
customized to meet any imaginable recommendation of the module manufacturer,
even retrospectively (see Know-how section
page 202).
Maximum energy yield
If the energy yield is to be maximized, then
a transformerless inverter is the only solution. In comparison to the galvanic isolating
devices, SMA inverters with patented H5
topology (see the Know-how section, page
204) provide an approximately two percent greater energy yield without having to
make cut-backs in personnel protection.
Block circuit diagram of a three-phase inverter of the Sunny Tripower type
Grid feeding
Good grid compatibility means more than
just grid-synchronized energy feeding. For
smaller PV plants, the symmetrical distribution of the feeding power across the three
phases is adequate and the responsibility
of the planner. For PV plants in the upper
power range, SMA inverters support the
grid management of grid operators with
the SMA Power Balancer, three-phase feeding, reactive power capability and other
options.

The listed examples show that diverse factors have to be taken into consideration
when designing a PV plant. Therefore we
recommend our free Sunny Design planning software for designing systems (see
next page). It helps with optimization and
makes the planner aware of critical combinations.

Plant design made easy
With Sunny Design, designing PV plants is easier than ever. Simply enter all required details and within a few
minutes you will receive the optimal plant configuration. The free software gives solar professionals and system
planners a user-friendly interface, and a practical input wizard helps with any questions. The software provides
data for an economic evaluation of the system along with technical checking of the various components. Thus,
the end customer gains a tailor-made PV plant and the solar professionals save valuable time.
12
Introduction to Inverter Technology
Sunny Design contains the most important
data of all SMA inverters as well as all currently available PV modules. It is easy to
use and guides the planner through the
entire design process. This saves time and
allows different configuration options to be
simulated without the need for complicated
calculations. Sunny Design calculates the
values automatically and comes up with
a comprehensive result for all design variants.
Operating states that could be critical
are reliably detected and identified. This
ensures that the planner is notified of any
deviations from the standard design. Such a
notification does not necessarily mean that
the design is not permissible, but it serves to
indicate that a thorough check is required to
see whether this operating state (e.g. generator voltage too low) is relevant in the
current plant.
Additionally, realistic operation is evaluated over a calendar year on the basis of
the integrated meteorological database.
Although an accurate yield forecast cannot be expected from Sunny Design (further
simulation programs with complex adjustment possibilities are necessary for this),
Sunny Design can determine the yield differences between the different designs and
also includes technical checking. Thus not
only can the best plant design be found, it
can also be evaluated how cost-effective
it is.

SMA Solarchecker
iPhone-App for estimating the yield of PV plant
"Is it worth having a photovoltaic plant on my roof?" A question that many home owners are asking themselves.
Specialists who own an iPhone 3GS can reply in just a few seconds – thanks to the Solarchecker from SMA. The
application for the iPhone estimates the possible current yield of a PV plant in no time at all – directly on site.

Introduction to Inverter Technology
Up until now, solar system engineers needed a long time before they could provide
potential customers with an initial yield estimation. Now, technicians can calculate
this estimate directly using an iPhone and
the SMA Solarchecker. This mobile device
features integrated sensors that allow it to
determine the location, orientation and tilt
of the roof fully automatically. The SMA
Solarchecker uses this data and some individual information such as plant size and
financing costs to estimate the planned
power and profits. Although the estimate
does not replace the final detailed planning of the system, it saves much valuable
time. And it convinces customers even faster of the benefits of these cost-effective and
environmentally friendly plants.
lar generator using the tilt sensor. The SMA
Solarchecker then uses these values to determine the specific yield of a PV plant, i.e.
the number of kilowatt hours produced per
kW of generator power.
Calculating the energy yield
with the Solarchecker
The iPhone as a solar power planner
To determine the energy yield, the planned
power of the PV generator must be calculated first. The SMA Solarchecker offers
two options for this: you can either give the
power directly in kWp or give the number
of square meters of the planned PV plant.
In the latter case, the App converts the entered roof area automatically into power.
Of course, the App takes into account the
PV module type that was specified in the
settings.
Firstly, the SMA Solarchecker finds the current location using the iPhone's GPS tracker. Using these values, the "App" (Application) determines the solar irradiation taken
from a database that would be theoretically possible at that particular GPS location.
Via the magnetic compass, the iPhone then
measures to what degree the roof deviates
from the ideal south-facing orientation. The
device determines the possible tilt of the so-
The SMA Solarchecker calculates the annual energy yield of the PV plant by multiplying the specific yield of the roof area
with the planned peak power. Long-term
estimates, e.g. over 20 years, are also
possible. For degradation, the SMA Solarchecker takes on a value of 0.2 percent
per year. Whoever wants to calculate
more precisely can increase this value accordingly.
Important information:
Since the returns and profits are dependent on the estimate of the specific yearly
yield, they both carry a certain degree of
uncertainty. SMA is therefore not liable for
lower actual yields that can also be due to
other factors such as shade and soiling of
the module. For more precise yield calculations, SMA recommends consulting a qualified technician or system planner.
Profit estimate at the press
of a button
The App can also estimate profits that are
possible with the planned PV plant. All you
need to do is to type in the current feedin tariff per kilowatt hour and the expected
financing costs.

Sunny Mini CenTrAl 7000hV
the champion for thin-film projects
Reduced installation costs thanks to greater input voltage range: with the Sunny Mini Central 7000HV, more
modules can be connected in series than with common inverters. This reduces cabling costs on the DC side
and simplifies the installation. Due to its galvanic isolation, the Sunny Mini Central 7000HV can be used both
with crystalline cells and thin film modules. Its performance range permits the installation of large PV plants
made up of smaller units, which allows for more detailed system monitoring. Its new reactive power and grid
management functions mean it is also suitable for international use.

Sunny Backup System:
Solar Power – Even in the Event of Grid Failure
A power outage means:
grid disconnection of the
PV system
No light, no heating, no computer: today, it is very difficult to do anything
without electricity. But how many PV
plant operators are really aware that
in the event of a power outage, the PV
plant is disconnected from the grid for
reasons of safety? From that moment
on it ceases to provide solar power –
neither for grid feeding nor for internal
power supply. And this is all the more
irritating because, as the experts agree,
throughout Europe, lengthy blackouts
and temporary outages are set to increase.
The SMA Sunny Backup-System closes
this supply gap. Now all owners of a
personal PV plant can continue to obtain reliable and environmentally-friendly power for important loads even in the
event of a grid failure.
Stand-alone power supply
The Sunny Backup System is the result of nearly 30 years' experience
in photovoltaic system technology –
both for grid-connected PV plants and
for stand-alone systems. The Sunny
Backup-System is a synthesis between
grid-connected operation and off-grid
technology that ensures optimum user
safety as well as ease of installation.
The system is equipped with a Sunny
Backup Inverter and is also available
as a fully pre-configured set solution for
all performance categories up to 100
kW.
will continue to function in agricultural
enterprises. Cold-storage units, hotels,
supermarkets and restaurants can remain in operation with no loss of image
or expensive disruptions to the cooling
chain. And heating, cookers, computers
and lights will continue to function with
no interruption in family homes, while
maintaining the same supply quality as
during normal operation.
Furthermore: all PV plants with Sunny
Boy inverters can be easily upgraded.
The optimum electricity insurance
Power outages can have very serious
economic consequences, especially for
businesses – unless the PV plant has
been equipped with a Sunny BackupSystem. With a Sunny Backup System,
barn ventilation and heating lamps

Solar power – even in the event of grid failure
Greatest performance and user benefits along with the lowest investment and operating costs: in comparison
with conventional emergency power systems, the Sunny Backup System scores well. As an ad-on to the PV plant
the Sunny Backup automatically switches to stand-alone power supply within approximately 20 milliseconds of
a grid failure. Both new and existing PV plants can be equipped with a Sunny Backup System – with no effect
on PV efficiency. And the best part: due to the integration of the PV plant, a small and therefore low-cost battery
can be implemented as it is usually only needed to bridge the night hours.

Central Inverters from SMA:
High Technology for solar power stations
Larger, more powerful, more efficient.
The success of photovoltaics has led to
constantly growing plant sizes in recent
years. With the Sunny Central product
line, SMA offers central inverters intended specifically for high performance
class installations. Thanks to their special
properties such as highest efficiency,
string monitoring, direct medium-voltage
feed-in, grid management and the possibility of outdoor installation, the devices
are optimally suited for use in solar power stations with homogenous structures.
An investment that pays off
From 100 kW Sunny Centrals up to
series-produced megawatt stations –
the Sunny Central inverters from SMA
are particularly economical. Whether
the Sunny Central HE series or the new
devices of the CP series for outdoor
use: SMA devices with efficiencies of
over 98 percent are the most efficient
in their segment. Furthermore, the HE
Outdoor
and CP series offer comprehensive grid
management functions (more on page
198).
Central inverters with their own weatherproof enclosures allow for installation
outdoors — greatly simplifying transport
and installation as a result.
Guarantee of reliability and
durability
SMA central inverters have been developed for a minimum lifespan of 20
years. This is because maximum investment security is only ensured when inverters operate reliably and flawlessly
over a long period of time. The SMA
plant monitoring assures additional
safety: thanks to numerous communications interfaces, operators can monitor their plant from any PC around the
world via the Internet. Yield variations
can therefore be recognized and resolved in good time.

High performance as standard
The completely new design of the Sunny Central CP series saves you real money. The compact and weatherproof enclosure is easy to load and transport and can be installed almost anywhere – there is no need for
heavy protective concrete substations any longer. The innovative cooling concept OptiCool allows it to operate
at full nominal power with ambient temperatures up to 50 °C. With the powerful grid management functions
you are perfectly prepared for today's utility requirements as well as those still to come. The intelligent power
management is the most important feature: in continuous operation, the Sunny Central 800CP can feed 880
kVA to the grid at ambient temperatures of up to 25 °C – that's 10 % more than the rated nominal power.

Sunny Central for Direct medium-voltage feed-in
800MV / 1000MV / 1250MV
High-performance medium-voltage station
For even more power: Two powerful Sunny Central HE inverters are components of a medium-voltage station
(MV) which feeds directly into a shared medium-voltage transformer. In this way, for example, two Sunny Central 630HE inverters are combined into a powerful Sunny Central 1250MV station. The advantage: By removing the need for low-voltage transformers, the efficiency is increased and at the same time the inverter costs are
lower. The Sunny Central MV also offers the best possible forecast for the future: It is the first central inverter to
fulfil the requirements of the medium voltage directive. An investment that also pays off in the future.

Sunny Central 200 / 250 / 250HE / 350
Direct line to the low-voltage grid
First choice for usage in medium-sized and large-scale PV power plants: with the proven Sunny Centrals 200,
250 and 350, plant operators can realize very good solar yields, especially in ground-mounted systems or roof
systems with homogeneous structure. The central inverters have five, eight or twelve fused inputs respectively
for the DC distributor box. Several devices can be connected together on the AC side. This makes generator
powers in the megawatt range possible. Whereas the Sunny Central 200, 250 and 350 feed directly into the
low voltage range, the Sunny Central 250HE can be connected directly to a medium-voltage transformer.

Sunny Central 250-US / 500-US
Perfect for commercial systems in North America
The two proven central inverters are ideally suitable for commercial plants in North America: The integrated
transformer makes possible direct connection with the low-voltage grid and, thanks to the outdoor enclosure
with the OptiCool cooling concept, the devices can be installed practically anywhere. The leading edge efficiency of 97.5 %, which is remarkable for transformer devices, is just as convincing as the simple monitoring
and remote maintenance via the integrated data logger – optionally with RS485, Ethernet or OPC interface.
Special highlight: when others switch off, the two Sunny Central inverters continue to feed at a lower output.
This means that in the temperature range of 122 to 140 °F (50 to 60 °C), up to 75 % of the nominal output
is still available.

Monitoring, Informing, Presenting
Yield Maintenance for Solar Power Systems
Sunday afternoon at the garden fence.
The sun is shining. Two neighbors are
talking. One neighbor points to the PV
system on the other's roof. "So, how
much is it generating right now?". The
system operator takes a quick look at
the Sunny Beam. The neighbor is impressed with the answer. It's a good
feeling: your solar power system is
doing what it should – feeding solar
power into the public grid and securing
you valuable yields. And best of all, the
system (practically) takes care of itself.
Thanks to the intelligent monitoring solutions from SMA.
Everything under control
Reliable and simple –
everywhere in the world
Comprehensive management is key to
profits for both small solar energy systems and giant solar parks. By choosing a solar power system, operators are
counting on environmentally friendly
technology as well as long-term profits. This means that the system must run
smoothly at all times. If output reductions in a system due to factors such
as shade on the solar module or faults
in the public electric grid go unnoticed
over longer periods, this can result in
substantial loss of profits. Continuous
system monitoring does not only entail
staying up to date on the amount of
solar power being produced, but being
able to react quickly to changes and
problems.
Modern system monitoring is much
more than simple control. It provides information regarding plant operation in
an easy to read manner and, thanks to
the Internet, to any location in the world
– for example, via E-mail. Additionally
the system data is presented simply,
cleary and professionally: in order to
have the system performance continuously in sight. Or for larger systems, in
order to present the ecological commitment for the benefit of the public.
Simple maintenance and
parameterization
SMA plant monitoring also provides
many benefits to installers. In the event
of a problem, installers have quick –
and, with Sunny Portal mobile – also remote access to all plant data. This data
allows contractors to draw conclusions
about a specific event and, for example, call the operator to check if a fuse
has blown. This can sometimes save on
the need for long distance service visits. SMA products are also useful for
plant maintenance and configuration.
With Sunny Explorer, for example, you
can access an inverter with a laptop
equipped with a Bluetooth interface.
Plant monitoring offers a variety of options: wireless or cable, compact or
complex, short or extensive. It makes no
difference whether the yield to be monitored is a single-family home rooftop
system or an open-air solar power plant.
And as a result of industry quality manufacturing devices for system monitoring
such as our inverters are designed for a
lifespan of at least 20 years.

Threefold simple and reliable
The right solution for every solar plant
Your PV system is unique and the system
monitoring can be put together just the way
you need it. Three different basic scenarios
are available for our customers to select
from.
Simple monitoring and control for
home rooftop systems.
For solar power systems on single-family
homes, for example, we recommend Sunny Beam or Sunny Explorer software. With
our user-friendly and compact products, the
operators can easily keep an eye on yields,
around the clock.
Reliable monitoring for solar
power stations
The larger the PV plant, the faster small reductions in power negatively affect yield –
if they remain undiscovered. With our solutions especially for solar parks, including
Sunny WebBox, the Power Reducer Box,
and the SMA OPC server, megawatt plants
can be monitored comprehensively and safely.
Modular system monitoring for
commercial solar power systems
For larger solar plants, a variety of components can be assembled to create a customized monitoring solution. In combination
with SMA solar inverters, operators and installers benefit from a perfectly-coordinated
system. The product spectrum of plant monitoring products includes Sunny WebBox,
Sunny Portal, Sunny SensorBox, Sunny Matrix and Flashview.

Sunny eXPlorer
the free Pc software solution
Switch on your laptop or PC, activate the Bluetooth interface, and start Sunny Explorer – that's all that's needed
to give operators and installers an overview of their PV plant. The free PC software is thus the optimum addition to the new generation of inverters with integrated Bluetooth. The key plant data can be visualized on the
PC or laptop – quickly and wirelessly with Bluetooth. Energy values and events can be archived long-term by
means of data export in CSV format, and processed and visualized in Excel. Sunny Explorer also provides
support during inverter parameterization: because no complicated cabling is needed, PV plant maintenance
is convenient and fast.

POWER REDUCER BOX
Feed-in management for large-scale PV plants
With the Power Reducer Box, SMA delivers a solution for large PV plants that must take part in feed-in management: it allows the grid operator to control the plant performance remotely. It achieves this by translating
the setpoint values transmitted via radio ripple control receiver into control commands for the Sunny WebBox,
which forwards them to the inverters. During this process, each change of status is logged twice: once in the
Power Reducer Box and once in the Sunny WebBox.The Power Reducer Box automatically transmits the data
to the Sunny Portal if desired – informing the operator immediately of the utility operator's requirements.

Secure connection with and without cable
To monitor solar power systems, data has to be transmitted. This can be power values or energy yields. For the
communication between the solar inverter and monitoring devices, SMA provides two basic choices: wireless
and wired variants. Both have advantages and are used with different sized systems. Here you can obtain more
information to decide which method of communication best suits your PV plant.

Wireless Success – Intelligently
Networked with SMA Bluetooth
Robust and Secure: powerful across
long distances with proven RS485
wiring
With SMA Bluetooth, wireless networks can
be created simply and quickly – without the
additional effort of having to lay cables in
walls, re-plastering or painting -- so it's perfectly suited to your private home rooftop
system.
Bluetooth, the international wireless standard, makes your monitoring flexible and
extendable. Installers and plant operators
save time and installation costs. Thanks to
Bluetooth all new inverters are recognized
in a flash and automatically integrated into
the system. With the intelligent networking
concept, up to 50 devices can be integrated in a network. Bluetooth Class 1 is the
used standard, which enables communication over longer distances. And if that's not
enough, for example because walls or ceilings are in the way, you can also use the
SMA Bluetooth Repeater.
Bluetooth also stands up in terms of reliability. Thanks to constant frequency changes
and the transmission of data packets in
small units, the radio connection is extremely stable. And the broadcast power is always adapted to the requirements at hand.
By the way: the password protection built
in to all devices secures your data against
unauthorized access.
The RS485 fieldbus is a veteran in the area
of cable-connected communication technology. It has been used by SMA for many
years and has proven itself in a nearly
endless number of systems. All devices
are connected to each other in a chain
(a so-called data bus). At the end of this
chain, the Sunny WebBox collects all the
data and reliably informs you of the status
of the PV plant. The advantage of RS485
wiring: functional lengths of up to 1,200
meters and reliable data transmission even
in interference-prone areas. Especially for
larger solar power systems, operators require maximum security and reliability.

Einführung Wechselrichtertechnik
Off-Grid Inverters by SMA:
System manager for all types of energy generators
Secure power supply for stand-alone
systems: the Sunny Island battery inverter forms a standard AC voltage
grid into which all users and generators can be easily integrated. With this
AC coupling and the Sunny Island as a
system manager, SMA delivers an innovative solution for supplying electricity
to remote locations and for creating an
emergency supply for areas with unstable grids.
Functional principle
The Sunny Island is a battery inverter
and is in charge of setting up a stable
stand-alone grid. In doing this, it holds
the voltage and frequency of the AC
grid constant within the specified limits.
Both users and generators are connected directly to this grid. If there is an energy surplus, the Sunny Island charges
the batteries; if there is a shortage, it
supplies the grid with energy from the
batteries. Thanks to its highly developed
battery management system, it can recognize the charge levels at any given
moment and, through its function as system manager, it makes further decisions
as well: if batteries are discharged or if
there is a great demand for electricity,
the Sunny Island can start a generator
or it can disconnect loads as needed.
If the batteries are fully charged and
there is little demand, it can reduce the
solar plant's electricity production. It also determines the optimal strategy for
charging the batteries, and in so doing,
increases their lifespan.
Flexible grid layout
In addition to solar and wind power
plants, diesel generators and other electricity generators as well as all 230-volt
loads can be connected to the AC
stand-alone grid. This does away with
costly DC cabling. For smaller systems,
SMA offers the Sunny Island Charger,
an MPP charge regulator for a DC connection of the PV plant and batteries.
This makes SMA the only company in
the world to offer coordinated solutions
for both AC and DC connections. The
special advantage: SMA stand-alone
grids can be set up quickly and can be
cost-effectively adapted to increasing
electricity demands.
Expandable up to 300 kW
Stand-alone grids using the Sunny Island 2012, 2224 or 5048 can be expanded without difficulty through the
parallel connection of several devices –
single-phase as well as three-phase. For
systems with more than 15 kW, three
Sunny Islands 5048s and a battery are
combined in a cluster. To reach the total
power desired, several of these clusters
can be connected in parallel. The advantage: even if a battery fails, only one
portion of the system is affected, which
ensures a secure stand-alone grid supply.

SMA DC coupling: maximum efficiency and applicable everywhere
AC and DC coupling optimally coordinated and, for the first time, from a single manufacturer: the allpurpose Sunny Island Charger 40 by SMA. Its broad DC input voltage range makes sensible system configuration possible for almost all PV modules. Thanks to the integrated MPP tracking system, the charger
guarantees an energy yield that is between 15 to 30 percent higher than that of conventional shunt and
serial charge controllers. Its unique features for charge controllers of this power range include the high
protection rating, fanless operation and the broad temperature range that makes worldwide use possible
even in difficult ambient conditions. The easy installation and completely automatic customization of the
key controller settings by the Sunny Island make its startup foolproof.

Multicluster Boxes for SUNNY ISLAND 5048
For easy set-up of stand-alone and hybrid systems
Large off-grid systems with minimum effort: the new Multicluster-Boxes for the Sunny Island 5048 are the
ideal solution for the easy installation of island and hybrid systems from 30 up to 300 kW. For this, 2 to 12
three-phase clusters, each consisting of 3 Sunny Island inverters, are connected in parallel. We designed the
Multicluster Box as an AC distribution center for connecting generators and to supply loads up to 300 kW
especially for these systems. To simplify installation, all Multicluster Boxes are completely wired and fitted at
the factory with a main connector for PV or wind generators. All communication cables required for the installation are included in the delivery.

Smart Load for Sunny Island
Intelligent dumpload for stand-alone grids
The Smart Load forms the perfect complement to unregulated energy generators in stand-alone grids, e.g.
small, directly-connected wind generators with passive stall power control. If there is an electricity surplus, the
Smart Load feeds it into special loads, for example heating cartridges in a hot water tank. The control system
is completely automatic, lightning fast and free of retroactive effects for other loads. This continuous and quick
energy consumption allows for ideal protection of system components and guarantees increased reliability.

WINDY BOY
Grid connection of small wind turbine systems
Versatile
Drawing on our experience of over six
gigawatts of installed inverter output
across the world, we developed the
Windy Boy series as an inverter family
for grid connection of small wind energy plants. The series includes a variety of device types for the 1 to 21 KW
performance range that are suited for
use with wind generators of a number
of different manufacturers and performance classes.
High Yields
A wind plant can only achieve high
yields when the inverter is ideally suited
to the wind generator's performance
characteristics. This is the advantage
of SMA's programmable polynomial
curve: because the performance curve
of wind turbines of all sorts can be depicted with a polynomial, the turbine
and the inverter can be optimally adjusted to one another. This improves
yields, especially when the wind speed
is low. The constantly changing slope
of the polynomial curve also minimizes
mechanical strain on the turbine by gently and gradually shifting the load, even
during significant speed fluctuations.
All-Purpose
Its transformer-based concept, the independent Grid Guard disconnection
device, the automatic 50 / 60 Hz detection, as well as certification for the
most important countries of installation
permit installation nearly anywhere in
the world, while ensuring low installation costs and simplified commissioning
procedures.
wind generator's speed dependant AC
voltage to DC voltage, and protects the
Windy Boy from high input voltages.
The input voltage is fed to an external
load resistance. The Windy Boy thus
converts the generated direct current to
alternating current suitable for the grid.
Reliable
Converting the wind energy plant's
speed dependant voltage to grid-compliant alternating current is easier than
ever: the Windy Boy Protection Box and
the Windy Boy make it possible to use
permanent magnet generators to connect small wind energy plants to the
grid for safe and reliable operation. The
Windy Boy Protection Box converts the

Windy Boy PROTECTION BOX
Optimal protection for small wind power plants
A rectifier and overvoltage protection in one – SMA's Windy Boy Protection Box can do it all: it protects the
inverter from excess generator voltage by feeding excess generator voltage to a load resistor, which slows
down the turbine. In addition, the Windy Boy Protection Box features a three-phase rectifier. It is delivered as
turnkey unit and can be used with nearly all types of generators made by different manufacturers in various
performance classes. The box is thus suited for use with wind plants as well as for other permanent magnet
generators such as small water power plants and CHP systems.

Hydro Boy Inverter for Fuel Cells
The clean alternative to diesel generators
Trend setting technology
How it works: the Hydro Boy efficiently
transforms the direct current generated by the fuel cell into alternating
current. To do so, it must operate with
low voltages and high currents. The
SMA Hydro Boy meets these special
requirements and is a proven device
that benefits from nearly 30 years'
experience with innovative power
supply systems.
Supplement to off-grid systems
Everything from a single source
SMA is the only manufacturer in the
world to offer AC coupled PV plants
for self-sufficient energy supply systems
ranging from one to 300 kW. Along
with off-grid and solar inverters from
SMA, the Hydro Boy is an important
component in a reliable standard AC
voltage grid. The H2 Island Extension
complements the necessary batteries in
a stand-alone grid with a fuel cell featuring a hydrogen accumulator.
From the reliable Sunny Island island
manager to the Sunny Boy solar inverter and Sunny Mini Central, from the
Windy Boy inverter for wind energy, to
the Hydro Boy: SMA supplies optimally
coordinated components for an ACcoupled stand-alone grid. Thus installing and expanding stand-alone grids is
easier than ever.
Advantages of fuel cells
In comparison to diesel generators fuel
cells are more efficient. They are quiet
and do not generate CO2, and are thus
especially environmentally friendly.
Since fuel cells generate heat, the H2Island Extension can also be linked to a
heating system which allows waste heat
to be used as heating energy. SMA cooperates with the leading heating system manufacturers and their research
and development departments.

Trendsetting and efficient: the Hydro Boy
inverters are ideal for an environmentallyfriendly expansion of off-grid systems
with SMA products. Whether for the energy supply of remote regions far from
the grid or to provide electricity in case
of emergency in unstable grids, the development of self-sufficient off-grid systems is an important future market. The
SMA inverters will become increasingly
popular for fuel cells as diesel and heating oil prices continue to increase.

inverter for standard fuel cell systems. The devices have a transformer on the grid feed-in side, which qualifies
them for direct grid feed-in anywhere in the world. For AC power scaling, the devices can simply be connected
in parallel. And as supplemental power sources in stand-alone grids, they are the ideal addition to SMA solar
and off-grid inverters.

Centralized or
Decentralized?
SMA has the right inverter concept for any PV plant
From kilowatt to megawatt, SMA is the single source manufacturer for the right solar
inverter of every size and for every site.
Thereby, the customer can choose among
various plant concepts. While a central inverter concept may clearly be the best solution for one PV plant, conditions in another
system, even a system similar in size, may
require a decentralized concept.
194
You must always consider installation and
plant operating costs in particular when deciding whether to opt for a centralized or
decentralized plant structure. Under certain
conditions, decentralized plant design has
been shown to offer a range of advantages
over centralized design. A few of the important aspects typical of the power class
above 100 kWp are noted in the following
examples.
Decentralized plant design:
precise and effective
Maintenance-friendly operation
under all conditions
If a PV plant is oversized or undersized,
this can have just as much of an effect on
the plant's energy yield as the inverter efficiency. Specific system performance can
be set precisely using small inverter units.
Together with a high degree of efficiency,
several smaller devices can present a better
alternative than one large centralized unit.
Maintenance work on decentralized systems is much less complicated and economical compared to centralized systems, as the
individual inverters can be replaced if necessary. Installing smaller and lighter devices
can be less expensive than a large heavy
concrete substation if ground load capacity
or site accessibility is limited.
Advantageous in mixed plant
structures
However, monitoring of a plant with a centralized inverter is easy to set up and covered by the standard hardware. Even the
required participation in grid management
for large scale plants can be implemented
particularly easily. And above a certain
plant size, decentralized concepts are simply no longer practical.
A centralized inverter such as the Sunny
Central works most effectively with a homogenous solar generator. Decentralized
concepts, such as those using Sunny Mini
Central inverters, are a better choice when
generator units differ and should thus be
operated separately. This can be caused by
using mismatched PV modules or modules
with a higher manufacturing tolerance, subgenerators that are oriented differently, or
tracking sub-generators.
nomical solution and evaluate them when
planning the specifics of your solution. Different condidtions may result in the fact that
a system generates profit on one site or
struggles with amortization on the other.
It is therefore wise to take advantage of
the technical advice and experience of the
SMA team when determining the optimum
plant structure and components for your
project.
Comprehensive analysis is important
These examples show that you really must
account for all costs (TCO: Total Cost of
Ownership) when choosing the most eco-
195
Design of PV plants
Three Steps to Success
The possibilities for plant design are vast.
There are many different module types,
various inverters, roof pitches, locations and
many more. The right design of a solar plant
is crucial for the anticipated yield. The most
important design decisions can be summarized in the following three steps. They take
196
the fundamental technical context as well
as guidelines and rules of thumb for the design of a standard PV plant in parallel grid
operation into account. If deviations from
the required standard conditions occur, the
specified guidelines must be modified accordingly.
1. Incorporate the inverter’s electrical
thresholds
First of all, the voltage of the generator must
match the inverter. The limits are defined
by the MPP voltage at the highest cell temperature (standard: 70 °C) and the open
circuit voltage at the lowest cell temperature
(standard -10 °C). The maximum plant voltage of the PV modules can also limit the
open circuit voltage of the generator.
2. Choose between optimizing the
economy or optimizing the yield
The performance ratio (relationship between
the maximum input power of the inverter
compared with the peak power of the PV
generator) provides information concerning
oversizing or undersizing of the inverter. To
utilize the full power of the PV generator
at all times, the inverter must be slightly
oversized (power ratio 110 %) However,
the economically optimal system is slightly
undersized. Therefore, the following decision must be made during the designing
process: Do you want to "squeeze" every
last drop of energy from the solar generator
at all times (optimize the energy yield) or
select a slightly lower inverter performance,
accepting minimal yield losses at higher irradiation levels (optimize economy)? Of
course, the answer to this question depends
largely on the economic conditions at the
plant location.
3. Use the maximum efficiency
of the inverter
Every inverter has an input voltage at which
its conversion efficiency is maximized.
Whether this voltage lies in the upper or
lower area of the operational range is, depends on the internal design and is listed
in the respective data sheet. If possible, the
MPP voltage of the PV modules at NOCT
(Normal Operation Cell Temperature)
should be close to this voltage.
Though professional design of a PV plant
includes many more steps, the three basic
decision steps above largely determine the
future yield. For this purpose, SMA offers
the free software SUNNY DESIGN, which
incorporates all the aspects of plant design
(more on page 12).

Inverters as grid managers
Overview of the grid management
functions of SMA inverters
It started in Germany in January 2009, following France in 2008: Since then, largescale PV plants have had to participate in
grid management, and provide grid services to an increasing extent. Experts unanimously agree that such measures are essential. The installed PV power increases
continuously, and individual projects are
growing larger and larger. Increasing size
and power also mean greater responsibility
for the electricity grid, as only a stable grid
permits unrestricted expansion of renewable energies. This was enough reason for
SMA to commit fully to participation from
the outset. SMA, technology leader in the
field of solar inverters, is now also a pioneer
in grid management.
* Renewable Energies Act (EEG)
198
Powerful grid management functions
For example, the SMA Power Reducer Box
was the first market ready solution for utility interaction management as defined in
Art. 6 of the German Renewable Energies
Act (EEG)* – and is also compatible with
virtually all SMA inverters. Inverters with an
automatic power reduction feature in case
of increased frequencies make a valuable
contribution to stabilizing the grid frequency if more energy is generated than can be
consumed. Reactive-power compatible inverters help keep the grid voltage constant,
but can also be used to compensate for
undesirable phase shifts. And the dynamic
grid support features support the grid in
the event of faults, and can also prevent,
or at least restrict, the fault from spreading
further.
1Generation and
grid stability management
2 Automatic active power
frequency control
Sixty seconds: Inverters in Germany have
just one minute to implement possible specifications of the utility operator. If a section
of the grid is overloaded temporarily, the
utility operator can and must limit the power
from decentralized generating systems The
plants make a major contribution to the stability of the grid, which can hardly keep
pace with the rapid expansion of power
from renewable energies in some cases.
The SMA Power Reducer Box von SMA
translates the incoming setpoint specifications of the utility operator into control commands for the Sunny WebBox. This in turn
forwards the commands to the connected
inverters via fieldbus, and logs the external
setpoint specification – which is important
for legally compulsory compensation for
possible resulting yield shortfalls.
The frequency in alternating current grids is
kept constant within strict limits – typically
at exactly 50 Hz or 60 Hz. The frequency
drops if more energy is consumed than the
generators feed-in. The opposite occurs if
there is an energy surplus – the grid frequency increases. SMA inverters can react
to this with an automatic active power reduction: The higher the frequency is above
the setpoint, the more they derate the active
power output. This stabilizes the grid and
prevents mass deactivation of systems due
to excessive grid frequency.
The grid levels in the AC power distribution grid
199
3 Static voltage support based on
reactive power
In order to protect the connected loads, the
voltage must be kept within defined limits –
that applies to the distribution grid in particular. With their ability to provided controlled inductive or capacitive reactive power,
PV inverters can help guarantee the voltage
quality required in EN 50160.
Reason: the increasing feed-in at low and
medium-voltage levels can result in voltage
increases which caused problems for the
previous grid operation method (flow of
energy from central generator to decentralized loads). Using reactive power, PV
inverters can now reduce undesirable voltage increases significantly. Reactive power-compatible inverters can also be used
to compensate for existing phase shift. As
even reactive power reduces efficiency, this
reduces the load on the grid infrastructure,
whose capacity limits may already have
been reached. Typical causes of phase
shifts include transformers, large motors or
even simply long cable sections.
200
There are several options for adjusting the
percentage of reactive power: Plant operators can use set points specified by utility
operator, or various reactive power values
can be set via an agreed schedule or remotely programmed via the SMA Power
Reducer Box. The third option is regulation
of the percentage of reactive power via a
characteristic curve depending on the grid
voltage measured at the connection point
or the active power output of the inverter.
4Dynamic grid support
Until now, PV plants had to disconnect
from the grid immediately, even during temporary drops in grid voltage. This meant
that many plants were deactivated in the
event of grid failure, unbalancing the grid
even further. Inverters with dynamic grid
support functions act within milliseconds
in such events, preventing the grid failure
spreading further. The so-called restricted
dynamic grid support ensures that the inverter is ready to feed energy into the grid
immediately after a drop in the grid voltage. Devices with full LVRT or FRT behavior
(Low-Voltage or Fault Ride Through) can
also feed reactive power into the grid during grid voltage drops. LVRT is already
supported by the new Sunny Central CP
series.

SMA inverters feed capacitive or inductive reactive power to the grid in order to stabilize the
grid voltage. Three different modes are available:
a) Fixed specification of the reactive power by the utility operator
The utility operator defines a fixed reactive power value or a fixed displacement factor between cos(ϕ)leading= 0.90 and cos(ϕ)lagging= 0.90.

Frequency-dependent control of active power
As of a grid frequency of 50.2 Hz, the inverter automatically reduces the active power output
according to a definable characteristic curve, helping to stabilize the grid frequency.

Remote-controlled power reduction in case of grid overload
In order to avoid short-term grid overload, the grid operator presets a nominal active power
value which the inverter will match within 60 seconds. The nominal value is transmitted to the
inverters via a ripple control receiver in combination with the SMA Power Reducer Box. Typical
thresholds are 100, 60, 30 or 0 per cent of the nominal power.

The right solar inverter
for every module technology
202
Besides conventional PV modules, new
cell technologies and other advancements
have been appearing on the market for
quite some time. Of these, some can only
be operated under certain conditions. For
this reason, the manufacturer's application
instructions must be observed when using
PV modules.
When selecting an inverter that meets the
special PV module requirements, the generator potential in operation of various inverter
topologies must be taken into account. The
adjacent diagram shows a chronological
map of potential courses of the generator
connections during operation using several
different inverters.
The versatile range of different topologies
allows a flexible application of SMA's
inverters – combined with the suitable
grounding set – providing the ideal device
for any module technology. Moreover,
SMA is in close contact with the module
manufacturers, which means that current
installation recommendations can be effortlessly observed.
To help you select the right inverter for
each module type, we have compiled the
most important current recommendations
for you. They are covered in the technical
information package "Module Technology"
and are explained in detail there.
2. Selection based on module
characteristics
If the manufacturer of the PV module does
not define any specifications for the use of
its products, we recommend choosing an
inverter based on the characteristics of the
PV module.
Example: Thin-film modules with CdTe or
amorphous silicone cells often use a TCOcoated pane of glass as a substrate for cell
construction. The right choice: Sunny Boy
with transformer and a negative grounding set.
Block circuit diagram: PV plant with positive generator grounding
Example: In case of flexible thin-film cells,
a stainless steel foil is often used as a substrate mount. Use an inverter topology in
which the PV generator only features a
small amount of AC voltage to the ground.
The right choice: Sunny Boy with a transformer or a device with no transformer
with Quiet Rail Technology (e.g. Sunny
Tripower). It prevents reverse effects of the
grid voltage on the generator potential via
special wiring.
The table below shows favorable combinations for many different cell technologies.

Maximizing the yields
with High-Tech by SMA
The technical details of SMA inverters benefit in particular from the expertise of our developers and their decades of experience.
Many innovative SMA technologies either
directly or indirectly increase the system
yield immediately.
H5 Topology – patented inverter
circuits for maximum efficiency
A modern inverter "consumes" between
three and six percent of the energy collected by the solar modules for conversion
of the direct current into alternating current,
which corresponds to an efficiency of between 94 and 97 percent. SMA's patented
H5 topology, an advanced circuit for the
inverter bridge, optimizes the current flow
in the inverter and thereby reduces the loss
during conversion. Basically the sinusoidal
grid current is produced using the high
frequency chopping and buffering of the
DC current in the inverter bridge circuits.
This leads to a costly oscillation of buffered
204
energy. A special synchronization of the
inverter bridges as well as the integration
of a fifth semiconductor switch prevents this
oscillation and reduces the conversion loss
to less than two percent. This is how the
inverters based on this technology reach
new levels of performance with efficiency
rates above 98 percent.
OptiCool –
Intelligent temperature management
The trend is clear: PV plants and inverters
are becoming ever more powerful while
installation conditions remain the same.
The effective heat dissipation from the
enclosure is thus increasingly important.
This is because increasing temperatures in
the enclosure reduce the performance and
lifespan of electronic components. With
the patented two chamber cooling system
OptiCool, SMA inverters offer an ideal
combination of passive and active cooling
which is worthy of the name "intelligent
temperature management." To maximize
the cooling effect, the entire inverter enclosure is a part of the cooling system. It
is divided into two separate chambers: the
front is sealed tight and thus offers the electronics solid protection against penetration
of water, dust and dirt. By contrast, all
components with a functionally higher temperature, such as chokes and transformers,
can be found at the back of the enclosure.
A temperature-controlled fan dissipates the
heat from this area though a special flow
tunnel to the outside. All in all, OptiCool
produces a lower component temperature
and assures maximum reliability and outstanding overload characteristics.
How OptiCool functions in the Sunny Boy 3800
OptiTrac –
Highly efficient MPP tracking
OptiTrac Global Peak –
Good yield in spite of partial shading
Every solar inverter has at least one: the
MPP-Tracker ensures that the solar module
always operates at its maximum power
(MPP). Since the MPP depends on the temperature and the strength of the irradiation,
it must be recalculated again and again.
It is essential that this process take place
as quickly and safely as possible. Irradiation conditions can change quickly and
often – on sunny days, a passing patch of
clouds can make this happen in just a few
seconds. OptiTrac is SMA's solution for just
this problem: sophisticated experiments at
the SMA Solar Test Center have resulted in
the refining of MPP tracking and the further
increase of its efficiency. It does not matter
if crystalline or thin-film modules are used.
Extensive tests and field trials confirm that
OptiTrac increases the energy yield of a PV
plant by up to 1.5 percent per year on average – money for the plant operator.
In order to always find the optimum operating point even in partially shaded PV plant,
an additional function, "Global Peak", was
added to the proven MPP tracking system.
It enables the inverter to almost fully use
the energy supply of the solar modules under all conditions. Reason: If the individual
modules in a string are shaded, the string's
power curve can suddenly show several
maximum points. In general, there is only
one operating point with the actual maximum power: The global maximum power,
which results in significantly higher power
compared with the other local maximums.
This is where the new OptiTrac Global
Peak gets interesting: as it reliably finds
the global maximum power, the available
energy of a partially shaded string can be
used almost fully.
The SMA inverters Sunny Boy 3000TL,
4000TL and 5000TL will be equipped with
OptiTrac Global Peak as standard from the
second quarter of 2010. Older devices of
these types can be upgraded via a software update. In the medium term, OptiTrac
Global Peak will also be available for the
Sunny Tripower.

A Sure Thing
SMA protection concepts for installation
and maintenance
Safety first – This is especially important
for the area of energy technology A whole
series of regulations and standards are
there to protect operators, maintenance
personnel, and the everyday user against
accidents with electricity. SMA sets the
benchmark by equipping all products with
exemplary safety facilities.
SMA Grid Guard Utility interface for use worldwide.
Most PV plants feed the solar energy directly into the power distribution grid using
an inverter. The regional utility operator is
responsible for this grid: They ensure that
the prescribed thresholds for voltage and
frequency are complied with, that the electricity grid is used effectively and is easy to
maintain in the event of a fault. Of course,
this only works if those feeding into the grid
comply with certain rules and can be selectively disconnected from the grid. The
automatic grid disconnection device SMA
206
Grid Guard prevents unintentional feeding
when the supply grid is turned off (islanding) as well as when the upper and lower
limits of the standards are exceeded. In this
way, it offers maximum protection for both
maintenance personnel and consumer alike
against excessive voltage and frequency.
Recognized safety standard
SMA was one of the first manufacturers
to incorporate the requirements of the utility operators in the functions of their solar
inverters. The maintenance-free automatic
grid disconnection function has been a
standard feature on the Sunny Boy inverters since 1995. The ongoing development
of the "SMA Grid Guard" represents a recognized standard for safety: in this kind of
active grid monitoring, the quality of the
connected grid is constantly monitored –
by monitoring voltage, frequency and impedance. Here, fail-safe operation must be
guaranteed so that periodic functional test-
ing by the utility operator is not necessary.
The first requirements for this safety concept were described in the German standard VDE 0126-1-1. They now include the
vast experience we have attained over the
course of more than a decade of safe feeding operations. Today utility operators in
other countries refer to these requirements,
and they modify them to suit the local grid
conditions or extend the requirements with
additional regulations. As the most modern
type of automatic disconnection device, the
SMA Grid Guard grid monitor can be used
easily throughout the world.
Grid monitoring increases availability
The continuous monitoring of the grid parameters guarantees a very high availability of the inverters on the grid. The software
can also adapt to difficult grid conditions
via an automatic learning process: It can
distinguish recurring events from faults and
therefore safely avoid unnecessary grid disconnections.
Country variants
The equipment described here complies
with the safety philosophy of the SMA inverters which is recognized in most countries
around the world. Moreover, SMA also offers products which are tailored for the special requirements of specific countries. While
these inverters contain all safety devices,
they may not always be in the design described here. For example, UL-listed inverters
are equipped with a special grid monitor,
a mechanical DC circuit-breaker and automatic ground monitoring (GFDI) to comply
with the currently valid UL regulations.
Electronic Solar Switch –
The first internal DC load disconnection
unit for solar inverters
Working on an electrical device generally
requires the power supply to be disconnected. A DC load disconnection unit that acts
as a circuit-breaker under load between
solar generator and inverter is therefore a
strict requirement in most countries. The goal
of the developers at SMA was to design a
disconnector which did not entail additional
installation costs, was simple and safe to
handle, and had no effect on the efficiency
of the PV plant.
The patented Electric Solar Switch (ESS)
is composed of a grip handle, which covers all socket outlets and plugs completely,
which prevents disconnection under load.
To disconnect the generator from the inverter, the complete grip handle must first
be pulled off. At the same time, an electrical
circuit is activated which prevents the occurrence of an electric arc, thus guaranteeing
maximum protection even if the DC lines are
disconnected incorrectly. There is no more
current present at the DC plug connection
which are now revealed – only the voltage
of the solar generator is still present.
The ESS works passively during normal grid
feeding, incurring absolutely no losses, and
thus has no influence on the efficiency of the
inverter. The ESS is also the only DC disconnector which guarantees continued further
use of the reliable PV plug connectors and
the high standard of protection against accidental contact in generator cabling in accordance with protection class II. This electronic switch, developed and patented by
SMA, thus brings added safety to all work
carried out on the PV plant, which exceeds
the standard requirements.

Your own power grid
AC and DC solutions for stand-alone systems
Electrical current, anytime, anywhere –
something we all take for granted. More
than two billion people, however, live in
another reality: in so called "remote areas",
far away from power plants and electrical
grids. And for this reason, they must do
without many of the conveniences of our
civilization.
Photovoltaic energy offers solutions like no
other technology: PV plants are robust, durable, easy to install and maintain. For years
SMA has been motivated to develop a selfcontained energy supply system based on
solar power. SMA is the only manufacturer
in the world to pursue not only the concept
of DC coupling, but also AC coupling,
which has a range of advantages. With AC
coupling, all loads and generators are connected using an AC voltage bus, whereas
with DC coupling, the interconnection takes
place in a DC voltage grid. For residential as well as industrial power generation,
AC coupling has been used throughout the
world, while DC coupling systems have
208
been employed mostly in small applications
of up to 100 watts as well as for telecommunications purposes.
Different Types of Coupling
There are three different concepts for establishing energy supply systems, which save
the generated energy in batteries: pure DC
coupling, mixed systems, and pure AC coupling. In the beginning, the first developments relied on pure DC coupling: both the
solar modules and the batteries were DC
voltage sources, so that a conversion of the
power with the then still expensive inverter
technology could be avoided. With a few
hundred watts of power, the performance
of this system was quite low and many of
the appliances consuming the energy, such
as lamps, radios or televisions, were also
available in DC voltage versions.
Variants of DC coupling
Powerful systems pose a difficult problem
for pure DC coupling: since the voltage
is generally limited to 48 volts for health
and safety reasons, the current is very high.
Sockets, cables and fuses rated to approximately 80 amps were required in order to
carry the around 3,700 watts of power output by a common household socket. The
costs for a setup of this type are noticeably
higher. Moreover there are very few 48 volt
DC compatible appliances in the world.
For this reason, mixed installations are
used, at least for larger solar energy supply systems: Inverters convert the lower DC
voltage of the batteries into grid conforming
AC voltage of 230 volts. Only the loads
were connected to this AC voltage, while
the PV modules and batteries were still connected to DC cables. This is acceptable
if the distance is limited – only a charge
controller is required to prevent the battery
overloading.
DC coupling: better with the Sunny Island Charger
The SMA Solution for DC Coupling
Since the PV module voltage varies with
the battery voltage, the solar modules in
such systems very rarely reach their optimal
operating point (MPP). In this way, as much
as 30 percent of the valuable solar energy
is lost. In order to avoid this, one needs
an MPP charge controller like the Sunny
Island Charger. It controls the power provided by the PV generator (current and voltage) to maximize the charge current. The
somewhat higher costs can be recovered
very quickly. the solar yield increases by
20 to 30 percent. The size of the PV plant
can be reduced accordingly, which more
than makes up for the additional costs of
the charge controller.
Flexibility with AC coupling
If the PV plant and the batteries are not
immediately adjacent to one another, the
optimal solution is a complete AC coupling:
instead of building an expensive DC grid on
the generator side, a solar inverter converts
the solar power into AC current and feeds
it into the existing stand-alone AC grid. This
can create a number of advantages:
AC coupling: the basis for a highly flexible stand-alone electricity supply
•Lower installation costs due to the lower
amperage and the AC voltage technology.
•Simpler and more flexible planning, as
the distance between solar generator
and battery is unproblematic. Feeding-in
energy into any point of the AC grid is
now a de facto possibility.
•Better usage of solar power especially
during high-use periods of the day.
•Utilization of technological benefits from
grid connection, such as optimized MPP,
high efficiency, OptiCool, etc.
Solutions for all stand-alone systems
SMA is the only manufacturer in the world
to offer maximum utilization of AC coupling
for stand-alone power supply systems. Both
the multiple award winning Sunny Boy and
the Sunny Boy Central solar inverters are
used for this. Smaller systems can also be
built as DC-coupled PV plant with the Sunny
Island Charger. No compromising in terms
of design, cost or installation: SMA offers
optimum solutions for all off-grid systems
ranging from two to 300 kW.
•Lower total costs for solar systems with
more than four kilowatts of power

Solar Power Systems
The appropriate inverter for every application
The future belongs to renewable energy.
Fossil fuels such as oil and coal are finite
resources, and damage the climate and
the environment. Photovoltaic plants, on
the other hand – with their low wear, good
scalability and generation which matches
consumption – are among the most effective measures for a reliable and sustainable supply of energy, not least because
the solar energy in question can cover our
global consumption more than a thousand
times over.
On the following pages, we show several
examples which demonstrate that the integration of solar power systems into the
visual appearance of our cities and countryside is highly successful. These systems are
not unsightly and often add to the aesthetic
value of many buildings. This is especially
214
true of open spaces, which, as waste land
with no previous use, gain a new practical
social function by means of the construction
of powerful solar power stations.
Photovoltaic systems are now used as the
basis of solar island grid systems in many
corners of the world in order to set up energy supplies in remote off-grid regions, which
would otherwise be unthinkable.

Glossary
Explanations Regarding Solar Technology
Central Inverter
Centralized inverters are particularly well
suited for use in PV plants with a homogenous structure (modules of the same kind
with identical orientation and tilt). They are
used for plants starting at 100 kW and, in
most cases, are designed for outdoor installation.
Dumpload
Here: load which can be spontaneously
activated in the event of an energy surplus;
can also be used to balance out strong
load fluctuations. Consumers with storage
capability (pumps, cooling units, boilers)
are the most energy sensible. However, for
the actual technical function, appropriately
cooled resistors suffice.
ESS (Electronic Solar Switch)
The ESS is a DC disconnection unit integrated into the inverter to safely disconnect
218
a solar generator from the inverter. The ESS
has a grip handle for ease of operation.
After pulling down the grip handle, the DC
plugs can be accessed and disconnected
with no risk of arcing. Disconnecting the
plug means that the disconnection from the
live generator is immediately apparent.
H5 – Topology
The inverter bridge with H5 topology features a fifth semiconductor switch, which ensures optimal efficiency during conversion
at an efficiency rate of 98 percent.
HF
HF stands for "High Frequency" and also
designates the new Sunny Boy series with
high frequency transformers. The compact,
galvanically isolating inverters provide very
high efficiency for devices with transformers.
Low-Voltage Ride Through (LVRT)
Network management function from the
field of dynamic grid support: when there is
a short disruption in grid voltage, the inverter does not switch off, as has been required
until now, but supports the grid with reactive
power. After the disturbance, it immediately
resumes feeding. In Germany, for example,
LVRT is required as of January 2011 for
plants at the medium-voltage level.
Maximum Power Point "MPP"
The operational point (current / voltage) of
the PV generator under which the highest
possible power under the prevailing conditions is harvested. The actual MPP changes
constantly depending, for example, on the
level of irradiation and the temperature.
MPP Tracker
A device that adjusts the voltage and
current of a PV generator so that it operates at its "Maximum Power Point".
MSD
Part of an “Mains monitoring with allocated Switching Devices". This is a mandatory
safety device which prevents power from a
solar energy system from being fed into an
external power grid when the public supply
grid is not functioning. This function is taken
over by the Sunny Boy and Sunny Mini Central using SMA Grid Guard, thus making a
regular test unnecessary due to their single
fault characteristics.
Multistring Inverter
An inverter which, to a great extent, combines the advantages of several string inverters (separate MPP tracking of individual
strings) and a central inverter (low specific
costs).
OptiCool
A patented enclosure concept by SMA, in
which the interior of the enclosure is divided
into two compartments. The chamber with
the sensitive electronics is dustproof and
waterproof. The second chamber contains
transformers and chokes as well as other
unsusceptible components, and can be actively cooled when necessary.
Optiflex
An innovative and highly-flexible design of
the Sunny Tripower: the Sunny Tripower features an asymmetric multi-string input with
two MPP trackers for custom-fit installation
with nearly unlimited numbers of modules
and maximum system efficiency.
Optiprotect
The Sunny Tripower features a completely
new and comprehensive safety concept: its
electronic string fuses, automatic string failure detection and overvoltage protection
that can be integrated into the enclosure all
work to monitor the PV plant, ensure safe
operation, and optimally secure your energy yield.
OptiTrac Global Peak
Another advance in our time-tested OptiTrac
MPP tracker for operation in partially-shaded
PV plants. This specialized operation management system ensures that the modules are
constantly operated at the point of maximum
power even when there are multiple maximum power points, without causing measurable yield loss (loss < 0.2 percent).
guard enables simple and reliable operation of SMA inverters on nearly all electrical
power grids worldwide.
SMA Plug-in Grounding
A grounding set for the new Sunny Boy HF
series. Grounding is quick and simple – an
easy plug-in without opening the enclosure.
The polarity is defined by the orientation in
which the grounding is attached.
String Inverter
In string technology, the photovoltaic generator is divided into separate module surfaces and each of these "strings" is assigned
to a separate string inverter. This technology reduces system costs while at the same
time substantially simplifying installation
and increasing the energy yield and plant
availability.
SUNCLIX
A DC plug system for all SMA inverters,
developed in cooperation with Phoenix
Contact. The field plugs can be connected
to almost any cable without tools, and are
included with inverters free of charge.
Power Balancer
The Power Balancer is a Sunny Mini Central
inverter standard function that prevents the
formation of an unbalanced load during
three-phase grid feeding. This is accomplished by connecting three inverters to a
three-phase feeding unit via a control line.
Quick Module
A removable communication and configuration module for the new Sunny Boy HF
series. The Quick Module contains the rotary switch for country-specific configuration
and the Bluetooth® NetID, as well as the
SD card slot. The optional Quick Module
RS485 also features an RS485 interface
and a multifunction relay.
SMA Grid Guard
The SMA Grid Guard concept monitors,
for instance, the voltage and frequency of
the connected AC grid according to predefined parameters. This serves to prevent
the formation of islanding in the event of
grid disconnection (see also "MSD"). Grid
