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.

The documentation supplied with the products is an integral part of the respective products. Keep the documentation in a convenient place for future reference and observe all instructions contained therein.

2.2 Safety Precautions

This section contains safety precautions that must be observed at all times when working on or with the SMA Flexible Storage System. To prevent personal injury and property damage and to ensure long-term operation of the SMA Flexible Storage System, read this section carefully and comply with the safety precautions at all times.

Danger to life from electric shock due to live voltage

High voltages are present in the SMA Flexible Storage System. When covers (e.g., an enclosure lid) are removed, live components can be touched, which can result in death or serious injury due to electric shock.

• When carrying out any work on the electrical installation, wear suitable personal protective equipment.

• Before removing a cover, disconnect the relevant device from voltage sources (see documentation of the relevant device).

:$5 1,1*

Danger to life from electric shock due to damaged devices

Operating a damaged device can lead to hazardous situations that can result in death or serious injuries due to electric shock.

• In all cases, only use devices when they are technically faultless and in an operationally safe state.

• Regularly check all devices for visible damage.

• Ensure that all safety equipment is freely accessible at all times.

• Make sure that all safety equipment is in good working order.

Danger to life due to incompatible lithium-ion battery

An incompatible lithium-ion battery can lead to a fire or an explosion. With incompatible lithium-ion batteries, it is not ensured that the battery management is intrinsically safe and will protect the battery.

• Ensure that the battery complies with the locally applicable standards and directives and is intrinsically safe.

• Ensure that the lithium-ion batteries are approved for use with the Sunny Island. The list of lithium-ion batteries approved for the Sunny Island is updated constantly (see Technical Information

"List of Approved Lithium-Ion Batteries" at www.SMA-Solar.com).

• If no lithium-ion batteries approved for Sunny Island can be used, you should use lead-acid batteries.

Danger to life due to explosive gases

Explosive gases may escape from the battery and cause an explosion. This can result in death or serious injury.

• Protect the battery environment from open flames, embers, or sparks.

• Install, operate, and maintain the battery in accordance with the manufacturer's specifications.

• Do not heat the battery above the temperature permitted or burn the battery.

• Ensure that the battery room is sufficiently ventilated.

• Remove watches, rings, and other metal objects.

• Use insulated tools.

• Do not place tools or metal parts on the battery.

Chemical burns and poisoning due to battery electrolyte

If handled inappropriately, electrolyte from the battery can burn the eyes, respiratory system and skin, and emit toxic fumes. This may result in blindness and serious chemical burns.

• Protect the battery enclosure against destruction.

• Do not open or deform the battery.

• Whenever working on the battery, wear suitable personal protective equipment such as rubber gloves, apron, rubber boots, and goggles.

• Rinse acid splashes thoroughly with clear water and consult a doctor.

• Install, operate, maintain, and dispose of the battery according to the manufacturer's specifications.

Risk of injury due to short-circuit currents

Short-circuit currents in the battery can cause heat build-up and electric arcs. Burns or eye injuries due to flashes may result.

• Remove watches, rings, and other metal objects.

• Use insulated tools.

• Do not place tools or metal parts on the battery.

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.
