2.1 Intended Use
The SMA Flexible Storage System supports increased self-consumption through the following measures:
• Intermediate storage of excess PV energy with Sunny Island
• Load control and PV system monitoring with Sunny Home Manager
The SMA Flexible Storage System does not form a battery backup grid in the event of utility grid failure (for installation
of a battery backup system, see Quick Reference Guide "SMA Flexible Storage System with Battery Backup Grid").
The SMA Flexible Storage System must only be used in those countries for which it is licensed or in those countries for
which it is approved by SMA Solar Technology AG and the grid operator. The grid configuration must be a TN or TT
system.
The SMA Flexible Storage System records the grid feed-in and purchased electricity with an SMA Energy Meter only.
An SMA Energy Meter does not replace the energy meter of the electric utility company. The grid feed-in and the
purchased electricity are transmitted to one Sunny Island via Speedwire. To enable this, the Sunny Island must be fitted
with the Speedwire data module Sunny Island.
The Sunny Home Manager must not be installed in PV systems in which a Sunny WebBox is installed.
In the SMA Flexible Storage System, the Sunny Island uses lead-acid batteries or lithium-ion batteries for energy storage.
A fuse switch-disconnector (e.g., BatFuse) must be installed between the battery and the Sunny Island. In systems with
lead-acid batteries, you must ensure that the battery room is sufficiently ventilated (see battery manufacturer
documentation). If lithium-ion batteries are connected, the battery management of the lithium-ion battery must be
compatible with the Sunny Island (see the Planning Guidelines "SMA Smart Home" at www.SMA-Solar.com).
Three Sunny Island inverters can be connected to form a three-phase cluster. A cluster is connected in parallel on the DC
side and a shared battery is connected. Only Sunny Island inverters of the same device type may be installed in a cluster.
More than one cluster cannot be connected.
The SMA Flexible Storage System can be installed at altitudes of up to 2,000 m above Mean Sea Level.
The following products must not be connected in the SMA Flexible Storage System:
• Sunny Island Charger or other DC charge controllers
•DC loads
The system must be used as intended. Any use other than that described in the Intended Use section does not qualify as
appropriate.

Risk of burns due to short-circuit currents on the disconnected Sunny Island
The capacitors at the DC terminal input area store energy. When isolating the battery from the Sunny Island, there is
still battery voltage present on the DC terminal temporarily. A short circuit on the DC terminal can lead to burns and
may damage the Sunny Island.
• Wait 15 minutes before performing any work at the terminal or on the DC cables. This allows the capacitors to
discharge.
Damage to the battery due to incorrect settings
Incorrect settings can lead to premature aging of the battery. Settings of the parameters in the menu 220# Battery
influence the charging behavior of the Sunny Island.
• Ensure that the values recommended by the battery manufacturer are set for the battery (for the battery technical
data, see the documentation of the battery manufacturer).
Destruction of devices due to electrostatic discharge (ESD)
If enclosure parts are removed, the devices (e.g., Sunny Island or PV inverter) can be damaged or destroyed if
electronic components or terminals are touched.
• Do not touch any electronic components in open devices.
• Ground yourself before touching any terminals.

3 Information and System Description SMA Solar Technology AG
3 Information and System Description
3.1 Requirements of the "VDE Forum Network Technology / Network Operations (FNN)"
The information below only applies for systems for which the following properties are all applicable:
• Only one Sunny Island is connected in the system.
• The grid operator requires compliance with the Technical Information "Connection and Operation of Storage Units"
of the FNN. Currently, only the grid operators in Germany require compliance with the above-mentioned Technical
Information (status: June 2014).
In these systems, the Sunny Island must be connected to a line conductor supplied by a single-phase PV inverter. If there
are only three-phase PV inverters connected in the system, the Sunny Island can be connected to any line conductor.
The requirements of the Technical Information "Connection and Operation of Storage Units in Low-Voltage Networks"
published by the FNN influence the discharge behavior of the Sunny Island inverter. In systems with one Sunny Island
and single-phase PV inverters, the SMA Flexible Storage System reduces the maximum discharge power of the
Sunny Island as required.
Example 1:
All PV inverters are single-phase and are feeding in asymmetrically
(Sunny Boy). The PV inverters are connected to one line conductor.
The Sunny Island must be connected to the line conductor into which
the PV inverters are feeding.
Example 2:
All PV inverters are single-phase and are feeding in asymmetrically
(Sunny Boy). PV inverters are connected to two line conductors.
The Sunny Island must be connected to a line conductor into which
a single-phase PV inverter is feeding. TIP: Connect the Sunny Island
to the line conductor being supplied with the least PV energy. This
will increase the control range for increased self-consumption.
Example 3:
All PV inverters are single-phase and are feeding in asymmetrically
(Sunny Boy). One PV inverter is connected to each line conductor.
The Sunny Island can be connected to any line conductor.
TIP: Connect the Sunny Island to the line conductor being supplied
with the least PV energy. This will increase the control range for
increased self-consumption.
10 FSS-IS-en-40 Installation Manual - Quick Reference Guide
SMA Solar Technology AG 3 Information and System Description
Example 4:
All PV inverters are three-phase and are feeding in symmetrically
(Sunny Tripower).
The Sunny Island can be connected to any line conductor.
Example 5:
The PV system consists of three-phase PV inverters (Sunny Tripower)
and single-phase PV inverters (Sunny Boy). The PV system is feeding
in asymmetrically.
The Sunny Island must be connected to a line conductor into which
a single-phase PV inverter is feeding.
The PV system is not ideal for the SMA Flexible Storage System.
The Sunny Island can only discharge the battery if less than 4.6 kVA
are being fed in on the line conductor of the Sunny Island at the
point of interconnection.
3.2 System Information
Recommendations for battery capacity
SMA Solar Technology AG recommends the following minimum battery capacities. The battery capacities apply for
a ten-hour electric discharge (C10).
• System with one Sunny Island: 100 Ah
• System with three Sunny Island inverters: 300 Ah
Connecting the Sunny Island
At terminal AC2, there are two terminals N and N
• Always connect the neutral conductor to the N
self-consumption. This ensures that the Sunny Island disconnects at all poles.
Device Types within a Cluster
All Sunny Island inverters must be of the same device type.
Requirements for The Router and Network Switches for Speedwire Devices
• All Speedwire devices must be connected to the same router.
• The router and optionally one or more network switches must fully support Multicast.
• The router must support "Internet Enabled Devices" with the interfaces SIP and STUN.
The most common routers and network switches support Multicast and "Internet Enabled Devices".

3 Information and System Description SMA Solar Technology AG
The Sunny Home Manager does not support wind power inverters or CHP plants
The Sunny Home Manager only supports PV inverters. If your system combines various AC power sources
(e.g., PV system and small wind turbine system), the Sunny Home Manager can only detect the PV inverters and limit
their power. In the Sunny Home Manager system, no wind power inverters or CHP plants are displayed in
Sunny Portal. Since the data from wind power inverters or CHP plants is not taken into account by the Sunny
Home Manager, the data calculated in Sunny Portal and the displayed diagrams may be inaccurate. However, you
have the option of displaying the wind power inverters via the Sunny Explorer software and configuring them if
necessary (see documentation of Sunny Explorer).
3.3 System Description
The SMA Flexible Storage System supports increased self-consumption through the following measures:
• Intermediate storage of excess PV energy with Sunny Island
• Load control and PV system monitoring with Sunny Home Manager
The Sunny Island uses the connected battery for the intermediate storage of excess PV e nergy. The Sunny Island measures
the grid feed-in and the purchased electricity with the SMA Energy Meter or via the energy meter on the Sunny Home
Manager. The battery management uses this data to regulate the charging and discharging of the battery. The grid
feed-in and the purchased electricity are transmitted to the Sunny Island via Speedwire. To enable this, the Sunny Island
must be fitted with the Speedwire data module Sunny Island.
The Sunny Home Manager receives location-based weather forecasts via the Internet and uses these to create a
production forecast for the PV system. In addition, the Sunny Home Manager determines how much energy is typically
consumed in a household at different times of the day and uses this to create a load profile of the household. The
Sunny Home Manager uses the production forecast and the load profile to determine favorable times for increased
self-consumption and selectively switches, for example, the loads connected to the SMA radio-controlled sockets on and
off. If required by the grid operator, the Sunny Home Manager also monitors the active power feed-in of the PV system.
If the set maximum value for active power feed-in is exceeded, the Sunny Home Manager sends power reduction
commands to the SMA PV inverters. The PV system can consist of PV inverters with BLUETOOTH communication and PV
inverters with Speedwire communication.
Prevention of derating losses
The SMA Flexible Storage System prevents derating losses which may arise due to the limitation of active power feed-in.
This is achieved by regulating the operation times of time-independent loads and the time and duration of battery
charging in accordance with the PV production forecast and the consumption forecast.
Example: The current daily forecast of the system predicts a limitation of active power feed-in around noon when the
energy requirement of the loads is very low and PV production is high. For this reason, derating losses can be expected.
According to this forecast, the system only begins to charge the battery in the late morning. The derating losses will be
reduced or avoided by charging the battery at this later time. The total excess PV energy generated in the morning will
be fed into the utility grid without derating losses (for details on power control, see Planning Guidelines
"SMA Smart Home").
Deactivation of the intermediate storage of PV energy during certain charging procedures
To increase the service life of the battery, the SMA Flexible Storage System regularly carries out full and equalization
charges (see the Technical Information "Battery Management" at www.SMA-Solar.com). During this charging process,
the intermediate storage of PV energy is deactivated and electricity may have to be purchased to perform the full and
equalization charges.

Procedure:
1. For PV inverters with integrated BLUETOOTH interface that communicate via Speedwire, set NetID 0 (see PV inverter
installation manual). This deactivates communication via BLUETOOTH.
2. Determine the NetID of the BLUETOOTH system:
• Install Sunny Explorer on a computer. Either run the installation file on the CD provided or download free of
charge at www.SMA-Solar.com.
• Determine a free NetID for the BLUETOOTH system using Sunny Explorer (see Sunny Explorer user manual).
• Quit Sunny Explorer. This will ensure that the BLUETOOTH network is set up via the Sunny Home Manager.
3. Set the determined NetID on the Sunny Home Manager and on all
devices with active BLUETOOTH interface (see documentation of
the BLUETOOTH devices). Note that the NetID must not be set to 1
if the Sunny Home Manager is intended to communicate with more
than one BLUETOOTH node.
