2 The Sunny Island 3324/4248
2.1 General Description
The Sunny Island 3324/4248 is a bidirectional battery power converter (battery
inverter and charger), ideally suited for use in stand-alone grid operation. This
inverter allows you to charge lead acid batteries, using power sources provided on
the AC side (e.g. generator, public grid, Sunny Boy). The Sunny Island 3324/4248
creates a 230 V AC stand-alone grid using the energy stored in the batteries,
allowing stable operation of connected loads and power generation devices (e.g. PV
inverters).
Energy sources can also be connected on the DC side, as long as the specified limits
are not exceeded (see section 12 "Technical Data" (page 61)).
The Sunny Island 3324/4248 is able to control a starter contact for a generator and
automatically connect or disconnect it to an AC-grid (see section 5 "Generator
Settings" (page 29)).
The Sunny Island 3324/4248 can also switch off particular loads if the batteries do
not have sufficient electrical energy available.
The Sunny Island 3324/4248 can be used in different system configurations.
Detailed information on the different stand-alone systems can be found in the
installation manual.

3 SafetyInstructions
3.1 Important Notes Regarding Operation
Please follow all operating and safety instructions in this manual. Failure to follow
these instructions could result in damage to the inverter and cause personal injury.
Carefully read through the safety instructions before installing and commissioning
the inverter.
Ensure that the safety instructions and manual are stored in an easily accessible
location.
Opening the inverter, and any
• electrical installation
• repair, maintenance, or
• modification
of the Sunny Island 3324/4248 may only be performed by a
qualified electrician.
Only qualified personnel may alter the settings of the Sunny Island
3324/4248. The settings are protected by the installer password.
All of the instructions in the installation manual must be observed.
Before commissioning the Sunny Island 3324/4248, read the
instructions in the relevant sections of this operating manual
regarding the Sunny Island 3324/4248 and the batteries.
When touching the inverter, please note that some parts of the
Sunny Island 3324/4248 housing heat up during operation. These
temperatures may exceed 60°C. There is a danger of burn injury.
This inverter was NOT developed to power life-sustaining medical
devices. The Sunny Island 3324/4248 may not be used in systems
where a power outage could result in personal injury.

Safety Instructions SMA Technologie AG
Page 16 SI3324/4248-14:FE2406 User Manual
Life-threatening voltages and currents occur within the Sunny
Island 3324/4248. Protection against accidental contact is only
guaranteed if the following points are followed according to the
installation manual:
• the inverter is mounted correctly
• all connections to the inverter are made correctly
• the inverter is properly grounded
• the housing cover is subsequently securely closed
If you believe that any of these requirements are not fulfilled,
contact your installer immediately, as ignoring any of these points
may cause life-threatening personal injuries due to the voltages
present (electric shock) or may cause damage to parts of the
system.
Only qualified personnel may mount and install the battery and
the Sunny Island 3324/4248. Handling batteries is dangerous, e.g.
batteries can produce very high currents if they are short-circuited.
All of the safety instructions and general instructions in the
installation manual must be observed.
Use only rechargeable lead acid batteries. The use of other types
of battery can lead to personal injury and material damage.
Open flame or smoking in the vicinity of the battery is NOT
permitted under ANY CIRCUMSTANCES.
Take care to ensure that no metal parts fall onto the battery. This
could short-circuit the battery or other electrical components, which
could cause a fire or an explosion.
Ensure that the battery room is sufficiently ventilated.
The own consumption of the Sunny Island 3324/4248 discharges
the batteries, in standby mode (inverter DC disconnect is on,
inverter is in STOP mode and must be started manually) this load
is about 4 W and in idle mode (inverter is on, in invert mode, no
AC loads are present) it is about 22 W. You should take note of this
when operating the Sunny Island 3324/4248 for longer times
without recharge possibilities (e.g. in winter with snow on your
modules).
In these cases, you should set the Sunny Island 3324/4248 to Stop
mode (see section 9.3 "Switching Off" (S. 83)) and disconnect it
from the batteries via the DC circuit breaker.

4 Operation / Commisioning
Before the first commissioning of the Sunny Island 3324/4248, read this "Operation"
section and become familiar with the inverter.
4.1 Control Elements
Functions, operating modes, parameters, data and fault messages are all displayed
in the two-line display of the Sunny Island 3324/4248. Use the arrow keys (↑ ↓), the
ESC key, and the ENTER key for navigation. The individual control elements can be
seen in the figure below.
The following table shows the key functions:
The DC circuit breaker switches the Sunny Island 3324/4248 on and off. Note that
all voltage sources (batteries, (stand-alone) grid, generator) must be disconnected
from the Sunny Island 3324/4248 before the inverter is free of voltage (see section
4.2 "Activation and Deactivation" (page 20)).

4.1.1 Explanation of the Light-emitting Diodes (LEDs)
A red LED and a green LED are located on the front side of the Sunny Island 3324/
4248. The following table explains their meaning:
4.1.2 Display
Information about the Sunny Island 3324/4248 is shown on the two-line LCD display.
Two lines are always shown when navigating up and down the menus.
During normal operation, the Sunny Island 3324/4248 shows the relative output
power, the operating mode of the inverter, the generator status (e.g. "L" see section
4.6 "Generator Request" (page 26)), fault messages and the status of the load
shedding and generator control relay.

4.1.3 Power Display
The output power and the battery charging power of the inverter are displayed by
means of the number of boxes which appear in the upper row of the display. This is
a relative indication of the inverter's output, i.e. if the boxes extend to the middle of
the scale, this shows that the Sunny Island 3324/4248 is operating at half of its
nominal output.
4.1.4 Relay Status
In the lower right-hand corner of the green display screen appear two "O"s.
Load shedding: the left "O" indicates the status of the load shedding relay of the
Sunny Island 3324/4248. "O" stands for "Off" or "Open". If the relay closes, the "O"
is filled.
Generator Start: the "O“ on the right-hand side indicates the status of the
generator control relay in the same manner. It is closed if the Sunny Island 3324/
4248 intends to start the generator.
Explanation of the energy flow direction display:
">" = DC to AC (discharging mode)
"<" = AC to DC (charging mode)
Explanation of the load status display:
"]" = Normal
">" = Overload

4.2 Activation and Deactivation
4.2.1 Activation and Startup
Proceed as follows:
1. Switch on the Sunny Island 3324/4248 by switching the DC circuit breaker to
the "ON" position.
2. The Sunny Island 3324/4248 begins the
initialization phase (INIT), during which it
performs a number of self-tests to check that
there are no faults in the system.
3. You must wait for this to finish.
4. As soon as the initialization phase is finished,
the message "To start press <ENTER>" is
displayed.
5. Now press <ENTER> and the Sunny Island
3324/4248 starts up.
6. A single beep is heard. The green LED on the
control panel of the Sunny Island 3324/
4248 illuminates.
This step assumes that the Sunny Island 3324/4248 has been
checked for
• correct connections,
•voltagesand
• polarities
by your electrician, and that it has already been commissioned. If
this is not the case, have this checked by a qualified electrician!
If the inverter does not display the "To start press <ENTER>" message but
displays an error message instead, this error must be corrected before the
inverter can be put into operation. For this purpose, refer to section 11
"Troubleshooting/Problem Solving" (page 55). Once all corrective measures
have been taken, switch off the Sunny Island 3324/4248, then wait for 30
seconds before starting again from point 1.
