Technical Description SI2012_2224-TEN082311 11

System Overview SMA Solar Technology AG

2 System Overview

The Sunny Island is a bi-directional battery inverter (battery inverter and charger) for off-grid
systems. The Sunny Island supplies consumers on the stand-alone grid side and charges battery
banks with the energy from grid-feeding units connected on the AC side.

High efficiency

The comfortable support of AC- and DC coupling as well as the expandability of the systems formed
with the Sunny Island guarantee highest flexibility. In addition, innovative technology allows the
Sunny Island to achieve a maximum efficiency of more than 93 %. Optimized for partial load
operation, its low open-circuit and standby consumption are convincing features. Because of its high
overload capability and integrated power management, overdimensioning of the Sunny Island is
not necessary.

Multiple Phase / Parallel Connection Capabilities

The parallel operation of up to three devices on a single phase of a battery or of three devices on
a three-phase system enables the Sunny Island to be used to set up stand-alone power supply
systems with outputs of up to 9 kW.

Automatic Generator Control

Thanks to its sophisticated generator management it can control connected diesel generators in a
particularly gentle and fuel-saving manner. It can also be integrated into the public grid. The Sunny
Island can also deactivate loads automatically if the battery does not provide sufficient electrical
energy.

Perfected Battery Management

The stand-alone grid's critical component, the battery, is monitored diligently and utilized optimally.
The intelligent battery management registers the battery's state of charge precisely. This makes
possible an improved utilization of the battery capacity, which means that smaller and thus more
cost-effective batteries can be used without affecting performance.

In order to prevent premature aging caused by incorrect charging and frequent deep discharge,
the Sunny Island has an intelligent charge control and reliable deep discharge protection. Because
of these functions the battery service life can be largely extended, in comparison with simpler
devices.

DC fuse

WARNING!

The Sunny Island 2012 / 2224 has no internal DC fuse.

Install an external DC fuse between the Sunny Island and the battery (see chapter 7.2
"DC connection" (Page 43)).

12 SI2012_2224-TEN082311 Technical Description

SMA Solar Technology AG System Overview

As an external DC fuse, the BatFuse secures the Sunny Island's battery connection leads.

In addition, the BatFuse allows the disconnection of the inverter on the DC side. You will find more
information in the technical description of the BatFuse. You can obtain the BatFuse as an accessory
from the SMA Solar Technology AG.

Simple Installation and Configuration

Despite the complex function of this battery inverter, the Sunny Island is easy to install and configure.
All the settings required for operation can be quickly and easily programmed in ten steps using the
"Quick Configuration Guide". Using the central operation concept referred to as "Single Point of
Operation", the system/cluster parameters are only set on the master device; all other devices adopt
the configuration automatically.

Menu Navigation and Data Archiving

The easy-to-understand menu navigation allows quick access to all important data, even while the
system is running. The Sunny Island can be controlled easily with the Sunny Remote Control 1
(SRC-1) external display. An MMC/SD card provides simple system supervision and thus simplifies
any service tasks.

Saving Data

Always use the MMC/SD card for saving data and events. This way, in case of a failure,
the SMA Solar Technology AG can help you quickly.

The Sunny Island monitors the set voltage and frequency limits on the grid and generator. If these
limits are not observed, it disconnects from the external source without interruption and changes to
stand-alone grid operation. The Sunny Island also has an integrated anti-islanding process in order
to prevent unintended islanding on the public grid. If this process is triggered, the system will also
change to stand-alone mode without any interruption.

You can use the Sunny Island within various system configurations.

• The graphic on the following page shows which components can be integrated into a stand­alone grid system.

• The graphics on the page after next show the different wiring options (1-phase, 1-phase
parallel and 3-phase).

Information

Observe the battery manufacturer's installation instructions, as provided with the battery
upon delivery, and the applicable standards and directives for installation of batteries
(EN 50272-2).

DANGER!

Death hazard due to

1. Explosion and fire

2. short circuit

3. Chemical burns due to leaking electrolytes

1. Smoking prohibited!

Do not allow open flames, embers, or sparks near the battery.

2. The metal parts of the battery carry voltages.

Do not place foreign objects or tools on the batteries!

Work on the battery with insulated tools exclusively!

3. Use protective clothing and eyewear when working on the battery.

4. During normal operation, it is not possible to accidentally touch the electrolyte.

Dimensioning for the Battery Capacity

To ensure a faultless operation of the island grid system, the SMA Solar Technology AG
recommends a battery capacity of at least:

• 175 Ah per Sunny Island 2224 (24 V) at C

• 350 Ah per Sunny Island 2012 (12 V) at C

10

10

If an AC-coupled PV plant is to be connected to the system, the SMA Solar Technology
AG recommends a battery capacity of at least:

• 200 Ah (C

) per kW of AC nominal power of the Sunny Boy inverter in the case

10

of 24 V systems.

• 400 Ah (C10) per kW of AC nominal power of the Sunny Boy inverter in the case
of 12 V systems.

Technical Description SI2012_2224-TEN082311 33

Installation SMA Solar Technology AG

Batteries must be accommodated in protected rooms, and sufficient ventilation of the installation
location must be ensured. In the case of batteries which are connected to one Sunny Island
exclusively, there is no need for protection against direct or indirect contact, due to the safety low­voltage.

It is not necessary to install such batteries in a separate battery room, or in a self-contained electrical
facility.

The necessary air volume flow for ventilation of the room which accommodates the batteries is
calculated as per EN 50272-2 as follows:

Q = 0,05 * n * I

* C10/100 [m³/h]

Gas

Q = required air flow volume

n = Number of cells

I

= maximal finishing charge rate

Gas

with C10 as the 10 hour nominal capacity in [Ah].

The cross-sectional area of the ventilation inlets and outlets (in the case of natural ventilation) is
calculated according to the following formula:

A = 28 * Q [cm

2

]

Sufficient dissipation of explosive gases is not always ensured in the vicinity of the battery. Therefore,
a safety distance must be observed, in the form of an air clearance in which no sparks or smoldering
materials are allowed.

The clearance distance is calculated as follows:

d = 5,76 * (C10)

1/3

[cm]

Installation of a battery with liquid eletrolyte.

With closed batteries, installation in an acid-resistant collecting tray is to be provided for
so that, in the event of a fault, leaking electrolyte cannot cause further damage.

Finally, install the battery bank in accordance with the installation instructions provided by the
battery manufacturer.

7.2 DC connection

WARNING!

The Sunny Island 2012 / 2224 has no internal DC fuse.

Install an external DC fuse between the Sunny Island and the battery as a protective
conductor. Dimension the fuse in proportion to the cable cross-section used.

• Sunny Island 2012: fuse NH01, 250 A (BATFUSE-B.0x)

• Sunny Island 2224: fuse NH00, 125 A (BATFUSE-A.0x)

7.2.1 Grounding

External grounding.

• External grounding of the negative pole of the batteries is possible, because the
batteries and the grid side are galvanically isolated within the Sunny Island. In this
case, make sure that the high currents that may occur under fault conditions can be
adequately diverted.

• If a connection is required, then this must be made separately, external to the Sunny
Island, by an installer.

• When grounding the battery, the Sunny Island's enclosure must be additionally
grounded, also in the DC area (see chapter 7.3.1 "Grounding" (Page 47)).

Calculating the Required Grounding Conductor Cross-Section

The SMA Solar Technology AG cannot state generally valid values for the cross-section of the
conductor required for the external grounding of the battery. The conductor dimensions depend on
the type and size of the battery connected, the external fuse (DC side) and the material used for the
grounding conductor.

Determining the wire cross-section

Exact calculation of the grounding conductor cross-section must consider the regionally
applicable standards and guidelines (e.g., DIN VDE 0100 Part 540).

The required cross-section of a (copper) grounding conductor can be calculated using the following
formula. Trigger times, e.g., for the integrated DC circuit breaker and short-circuit currents of
between 2000 and 10,000, are typically about 25 ms.

I

SC

S = cross section of the conductor in mm²

A grounding conductor of 10,000 mm² cross-section is thus adequate for short-circuit currents up to
16 A.

7.2.2 Connecting the Battery

Connect a suitable battery to the DC side (see section 20 "Technical Data" (Page 197)).

WARNING!

Risk of lethal electric shock when the battery is connected!

Connect the NH fuse to the BatFuse-A.01 bracket or close the DC fuse disconnector only
after completing all installation work on the island grid system.

The DC connection must be made observing all valid regulations (e.g., DIN EN 50272-2, "Safety
requirements for Batteries and Battery Systems - Part 2: Stationary Batteries").

WARNING!

Danger of burns or even death due to arcing and short-circuiting when
connecting the battery.

• All safety and maintenance instructions provided by the battery manufacturer must
be heeded.

• Use special (insulated) tools to mount and install the battery.

• Please observe the correct cross-section and polarity of the leads connected to the
battery.

DC Cables

The DC cables should be as short as possible (in any case < 30 m). Long cables and
insufficient cable cross-sections reduce the system efficiency as well as the overload
capabilities. Do not lay the battery feed cables under plaster or in armored plastic pipes.
High currents flow through the battery cables, so they can become very warm.

44 SI2012_2224-TEN082311 Technical Description

7.3.1 Grounding

Information

In stand-alone configurations, the (protective) ground of the Sunny Island and its
individual components must be wired as a TN grid only. All valid standards and
guidelines must be taken into account!

CAUTION!

Danger of injury due to leakage current against PE.

The N connection of the Sunny Island has NOT been connected with PE by default.

• Ground the island grid system outside the Sunny Island before commissioning (see
chapter 7.3.3 "AC2 (Gen/Grid)" (Page 50)).

• For safety technical reasons (leakage currents of over 3.5 mA),

- two protective ground wires with 6 mm² (double ground) or

- one protective ground wire >10 mm².

For the ground connection with two redundant protective leads use the PE connections in the AC
connection area of the Sunny Island.

For the ground connection with the protective lead of > 10 mm² use the addtional PE connection
(PE crown on the enclosure) in the DC connection area (see following segment).

Additional Grounding of the Housing.

If the Sunny Island is used in a country which prescribes the use of a second protective ground (e.g.,
Switzerland), you can ground the enclosure additionally by using the PE crown in the DC
connection area.

Proceed as follows:

1. Strip the protective conductor.

2. Fit the protective conductor with a ringed cable
lug (max. cross-section 50 mm²).

3. Screw the ringed cable lug onto the enclosure's
PE crown (screw: M8 x 20 mm).

7.5 Communication

7.5.1 Communication with Sunny Island

The Sunny Island can be connected in parallel or in a 3-phase system with up to two other Sunny
Islands in order to increase the overall power. The devices communicate through CATe-FTP patch
cables (with two RJ45 plugs each). A patch cable is referred to subsequently as a communication
lead.

Notes on the Installation

1. Lay the communication cable separately from the AC cables.

2. DO NOT feed the communication leads through the membranes with their plugs
mounted. Feeding the plugs through the membrane would overstretch it, so that
there would no longer be a tight seal around the cable itself, which is thinner.

3. If the length of the provided communication cables is insufficient, use commercially
available Cat5e FTP cables (single shield) with gold contacts.

4. The maximum cable length is 30 m. The cable cross-section is at least AWG26/7.

Installation in a Single-Phase, Parallel System or in a 3-Phase System

• A communication cable is included with each Sunny Island.

You need the cable in order to establish an (internal) communication between
several Sunny Islands. If you operate only one Sunny Island in the cluster the cable
is not required.

• If needed, choose a parallel/multiphase configuration in the Quick Configuration
Guide (see chapter 9 "(First) Commissioning" (Page 75)).

Install the communication cable as follows:

1. Lay the cable equipped with RJ45 plugs through one of the four openings in the inner rubber
element of the cable conduit seal.

7.6 Additional Connections

7.6.1 Battery Temperature Sensor

The battery temperature sensor measures the temperature of the connected battery. This is necessary
since the optimum charging voltage for a battery largely depends on the temperature. Further
information is provided in section 12.4 "Charge Control" (Page 122). A battery temperature sensor
is provided with the Sunny Island (see the delivery scope description).

Defective Battery Temperature Sensor

If the battery temperature sensor is rendered inoperative, e.g., due to a short circuit or
broken cable, the Sunny Island works with a fixed setting which, however, leads to an
insufficient charge of the battery in the long run. In this case the Sunny Island's display
shows a warning.

• Replace the defective battery temperature sensor promptly.

• Always operate the Sunny Island with the battery temperature sensor (included in
the delivery).

NOTICE!

Damage to the battery due to faulty installation

• Always install the battery temperature sensor included in the delivery.

• Do not drill holes into the battery when installing the battery temperature sensor.

- Fasten the battery temperature sensor to the outside of one of the battery cells.

- Choose a position in the space between two cells or in the middle area of the

battery bank, where the heat generation during operation is greatest.

One battery temperature sensor per cluster!

A battery temperature sensor is provided with each Sunny Island.

Only one battery temperature sensor, which is connected to the corresponding master, is
required for a cluster.

SMA Solar Technology AG Sunny Island Electrical Connection

7.6.2 Battery Current Sensor

In addition to the internal measurement, the Sunny Island provides the possibility to measure the
battery current via a shunt. You need this function if you intend to operate additional DC generators
and DC loads in your island grid system.

NOTICE!

Damage to the battery due to the connection of additional DC generators or DC
loads to the island grid system.

In this operating situation, the Sunny Island's internal current measurement works
imprecisely; the charge state of the battery is not determined exactly.

• Install an external battery current sensor (shunt).

Battery Current Sensor

Install a battery current sensor if there are charge or discharge DC currents of over
200 A.

Connect the battery current sensor to the master.

Use cables of intrinsically safe circuits.

Always use cables of intrinsically safe circuits for the connection of battery current
sensors. "Intrinsically safe" means here that the cable is double-insulated and that the wire
melts but the insulation remains intact in the event of a short circuit. In addition, the cable
is not combustible. In order to avoid measuring errors, make sure to use twisted cables
(see DIN VDE 0100-430).

When connecting the battery current sensor proceed as follows:

1. Pierce the rubber plugs with a pointed tool.

2. Fit the cables with wire sleeves.

3. Introduce both cables from the outside through
the opening.

Technical Description SI2012_2224-TEN082311 61

Installation notice

The battery current sensor must be looped around the negative pole of the battery. In
addition, the contact of that battery current sensor which is connected to the Sunny Island
(1) must be connected to the terminal "BatCur+" (see following diagram).

If the battery current sensor is connected as described above,

• positive battery current means that the battery is discharging (current from the
battery)

• negative battery current means that the battery is charging (current into the battery)

Information

Charge controller and PV in the illustration above are only examples.

Island during the first commissioning of the island grid system (see chapter 9.3
"Commissioning the Battery Current Sensor" (Page 81)).

7.6.3 Multi-function Relays 1 and 2

DANGER!

Death hazard due to faulty insulation

Separate the relay cable safely away from the communication area.

• Strip the wires of the relay cable.

• Fit each individual wire with the silicon tube included in the delivery.

• The device should not be operated without the silicon tube.

The Sunny Island offers you several options for the control of internal and external processes. To this
end, the device is equipped with two multi-function relays to which you can assign functions with the
parameters "241.01 Rly1Op" and "241.02 Rly2Op" (see chapter 14 "Relay" (Page 152)).

Information

The slave devices' relays can also be used and programmed separately.

Information on the switching capacity of the relays is provided in section 20 "Technical
Data" (Page 197).

Technical Description SI2012_2224-TEN082311 63

Sunny Island Electrical Connection SMA Solar Technology AG

Operating principles of the relays

The relays are changeover contacts; they can be used as normally closed contacts
(NCC) or as normally open contacts (NOC).

The relay functions are listed as NO contact functions, in other words, the contact is
closed if the relay is activated by selecting the function. An exception is "Alm" (alarm), in
which case the relay has a break function. This means that the relay is normally activated,
opening the contact. Only in case of a failure is it deactivated and closes the contact
(activating, for example, a warning light).

Please note:

You can only assign one function to the relay.

Proceed as follows when installing the relay connections:

1. Pierce the rubber plugs with a pointed tool.

2. Fit the cables with wire sleeves.

3. Introduce both cables from the outside
through the opening.

4. Insert the wires in the "Relay1" or "Relay2"
sockets of the 3-pole terminal clamps
provided.

5. Tighten the screws on the sockets.

6. Pay attention to the designation of the pins:

- NC: Normally closed (closed when

idle)

NC

C

- C: Contact (operation contact)

- NO: Normally opened (opened in

SMA Solar Technology AG Sunny Island Electrical Connection

Load shedding

The Sunny Island can automatically switch off loads to protect the batteries from deep discharge.
To do this, an external (AC or DC) power contactor must be installed between the Sunny Island and
the loads (see also chapter 19.3 "Accessories (Optional)" (Page 195)).

NOTICE!

If a relay is used for load shedding, the loads connected to the power contactor will no
longer be supplied with electricity in the event of a fault in the island grid system, even
when the grid is available.

Generator Start

The Sunny Island can control generators. It supports generators that can be started and stopped by
a single contact and generators that require more than one contact (in combination with the
optionally available generator manager (GenMan)).

Default Setting of the Relays

By default, relay 1 is set to the start generator function "AutoGn" and relay 2 is set to the
load shed function "AutoLodSoc".

The first figure in section 2 "System Overview" (Page 12) shows the principal connection.

7.6.4 BatVtgOut Power Supply

The battery voltage is conducted to the outside at these terminals. It is fused at both poles by PTC
thermistors (max. 0.75 A) and can fluctuate depending on the battery status. This connection can,
for example, be used to supply a DC contactor for load shedding.

Proceed as follows when connecting the power supply:

1. Pierce the rubber plugs with a pointed tool.

2. Fit the cables with wire sleeves.

3. Introduce both cables from the outside
through the opening.

4. Plug one wire into each of the "BatVtgOut"
contacts of the 4-pole terminal included.

5. Tighten the screws of the contact.

6. If needed, install DigIn before you insert
the plug into the "DigIn BatVtgOut" socket
on the board.

7.6.5 DigIn Digital Input

These terminals function as a digital input for external electric sources. For example, the feedback
contact for the GenMan (GenRn) is connected here.

Information

If you connect a GenMan, or operate the system with the generator and utility (GenGD)

7.7 Configuring a System with Several Sunny Islands

1)

The Sunny Island can be configured for various system combinations:

• Single-phase system with one Sunny Island

• Single-phase system witn two or three Sunny Islands connected in parallel

• 3-phase system with three Sunny Islands (one Sunny Island per phase)

Carry out the configuration before the first commissioning of the system. Each Sunny Island must be
configured with the aid of the rotary code switch. Upon delivery this rotary code switch is set to "0".

Please note:

The position of the rotary code switch must only be changed if you intend to operate more
than one Sunny Island in your system!

The rotary code switch is found on the back of the back of the display, on the inside of the lower
enclosure cover of the Sunny Island.

To configure the system proceed as follows:

With a screwdriver (2.5 mm), turn the mark on the rotary code switch to the desired position.

Set the rotary code switch to

-0 for master

- 1 for slave 1

- 2 for slave 2

1)

These applications are only possible with firmware versions 3.0 and above.

2. Connection to the public grid/a generator:

•  = the Sunny Island monitors the grid limits (grid operation)

• x = the Sunny Island monitors the generator limits (operation with generator)

3. MMC/SD card (memory card) in the Sunny Remote Control 1:

• ¿ = card inserted

• = card missing

4. These indicators label the energy flow direction of the

•  = grid/generator

•  = battery

•  = Consumers

There are four operative states:

• ‡‡ = the grid/generator charges the battery and supplies the consumers

• ‡‡‡ = the grid/generator supplies the consumers

• ‡ = the grid/generator charges the battery, there are no consumers connected

• ‡ = the battery supplies the consumers

5. The state of the external sources are described by the following symbols:

• * = The grid/generator voltage and frequency are within the set limits

• ? = Generator voltage and/or frequency are outside of the set limits. The Sunny
Island will not connect the generator to the stand-alone grid while this situation exists.

• ! = The maximal admissible grid/generator reverse power was exceeded, the
Sunny Island has disconnected the grid/generator from the stand-alone grid.

The following characters indicate why the generator was deployed:

• B = Battery = The generator was deployed due to the battery's state of charge.

• L = Load = The generator was deployed due to a load-dependent generator
requirement.

• S = Start = The generator was deployed due to the operator's manual switching of
the generator activation on the Sunny Island from "Auto" to "Start". The generator is
no longer controlled automatically nor switched off by the Sunny Island.

• T = Time = The generator was run for an hour by the Sunny Island via the parameter
setting "Run1h". After this period the Sunny Island switches off the generator
automatically.

Technical Description SI2012_2224-TEN082311 95

Operating the Sunny Island SMA Solar Technology AG

The display changes

The generator status and the reason for its deployment are shown (alternating)
under "Generator-Status" in the display.

• If, for example, the display changes every 3 seconds from "*" to "B", this
means that the generator voltage and frequency lie within the specified limits
and that the generator was requested as a result of the battery charge level.

• If the generator has been manually set to "Stop", then no generator status
information is shown on the display. The field remains empty.

6. Relays

= relay activated
o = relay deactivated

7. Warning:

! = Warning

The symbol blinks until you have seen and cleared the warning in menu "410# Fail
Current" or "420# Fail History".

Faults: If there is a fault, the device goes into standby. A fault notice appears on the
display. Acknowledge and clear the fault; then the Sunny Island can be restarted.

Change to Standard View 1

The display switches to standard view 1 (home screen) automatically if the Sunny Remote
Control 1 has not been used for more than five minutes (inactivity).

Display Illumination

The background illumination is automatically deactivated after a short time of inactivity.
Switch the lighting back on by turning the pushbutton slightly. This turning changes no
settings; it only reactivates the display illumination.

Message Displays

Messages are displayed at all times during operation, they have priority over the
standard view 1 (home screen).
