2.1 Intended Use
The Multicluster-Box is the main AC distribution board in a multicluster system. The multicluster
system forms an AC grid and is made up of a maximum of 2 clusters (each three-phase).
Do not exceed the maximum AC connection power of the Multicluster-Box. Cables with copper
conductors must be used for the installation.
The Multicluster-Box is designed for connection to TN-S- systems.
The Multicluster-Box must only be operated in conjunction with Sunny Island 6.0H (SI6.0H-13 /
SI6.0H-12) or Sunny Island 8.0H (SI8.0H-13 / SI8.0H-12). Always take the maximum AC
connection power and the permitted inverter combinations into account.
In terms of interference immunity, the product is suitable for EMC environment A, and in terms of
EMC emissions, it is suitable for EMC environment B (as per IEC 61439-1:2011).
The product is designed for indoor use only.
Only operate the product at temperatures between −-25°C and +60°C.
The Multicluster-Box is designed for use at altitudes of up to 2000 m above Mean Sea Level. If you
would like to use the Multicluster-Box at altitudes above 2000 m, contact Service (see Section14,
page36).
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.

DANGER
Danger to life due to electric shock when live components or cables are
touched
High voltages are present in the conductive components or cables of the product. Touching live
parts and cables results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and make sure it cannot be reconnected
before working on the device.
• Wear suitable personal protective equipment for all work on the product.
CAUTION
Risk of burns due to hot components
Some components and terminals inside the product can become hot during operation. Touching
hot components or terminals can result in burn injuries.
• Wear suitable personal protective equipment for all work on the product.
• After opening the product, wait until the components have cooled down.
NOTICE
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Do not open the product during a dust storm or precipitation.
• Close the product in case of interruption of work or after finishing work.
• Only operate the product when it is closed.
• Store the closed product in a dry and covered location. Observe storage conditions.
Effects of an emergency disconnection
Emergency disconnection on the battery inverter triggers the uncontrolled shutdown of the
system and unsaved data is lost.
• Only trip the emergency disconnection to avoid danger or consequential damage.
• In the event of an emergency disconnection, always check whether any fuse elements in
the product, such as circuit breakers, have tripped.
• If any fuse elements have tripped, reactivate these fuse elements.

4 Product Overview
4.1 Product Description
The Multicluster-Box is an SMA multicluster technology device for off-grid systems, battery-backup
systems, and systems for increased self-consumption. The Multicluster-Box is a main AC distribution
board to which you can connect up to 2 clusters. Each cluster is three-phase and made up of 3 DC-
side, parallel-switched SunnyIsland 6.0H / 8.0H inverters with firmware version 3.5 or higher.
Functions of the Multicluster-Box include:
• Main AC distribution board for Sunny Island inverters, one generator, one load, and one PV
system
• Load shedding
• Automatic bypass and reverse current monitoring for the generator
• Active anti-islanding
