2.1 Intended Use
The multicluster system forms an AC grid and is made up of several three-phase clusters. Three SunnyIsland are
connected in parallel on the DC side of each cluster. The multicluster system can be set up as an off-grid system or as a
system with increased self-consumption and battery-backup function.
The Multicluster-Box and Grid-Connect-Box do not replace the distribution board for the loads or the PV system. In
addition to the Multicluster-Box and Grid-Connect-Box, you must install the necessary protective devices for the loads
and the PV system.
Loads connected to the SunnyIsland must have an CE, RCM or UL identification label.
The product is not suitable for supplying life-sustaining medical devices. A power outage must not lead to personal
injury.
Only device types with the same output power may be installed in a cluster. This means that the device types, such as
SI6.0H-12 and SI6.0H-13, may be combined within a cluster. In contrast, device types with different outputs (e.g.
SI6.0H-13 and SI8.0H-13) may not be combined. The cluster master must always be an SI6.0H-13 / SI8.0H-13. It
must be equipped with the latest firmware version.
An utility grid connected to the multicluster system must be a TN or TT grid configuration. The technical connection
requirements of the grid operator and the local standards and directives must be fulfilled. When connecting the
multicluster system to the utility grid, all information in this quick reference guide and the instructions provided in the
enclosed documentation must be observed.
Generators must be suitable for TN systems and must always be connected to the Multicluster-Box.
The entire battery voltage range must be completely within the permissible DC input voltage range of the SunnyIsland.
The maximum permissible DC input voltage of the SunnyIsland must not be exceeded. A battery fuse must be installed
between the battery and the SunnyIsland.
With lead-acid batteries, the battery room must be ventilated in accordance with the requirements of the battery
manufacturer and with the locally applicable standards and directives (see documentation of the battery
manufacturer).
The following conditions must be satisfied for lithium-ion batteries:
• The lithium-ion battery must comply with the locally applicable standards and directives and must be intrinsically
safe.
• The battery management of the lithium-ion battery used must be compatible with the SunnyIsland (see the
technical information at “List of Approved Batteries”).
• The lithium-ion battery must be able to supply enough current at maximum output power of the SunnyIsland (for
technical data see the SunnyIsland operating manual).
An DC supply grid may not be established with the SunnyIsland.
The AC sources in the multicluster system must be suitable for stand-alone mode with SunnyIsland (for PV inverters see
planning guidelines "Design of Off-Grid Systems with SunnyIsland Devices" at www.SMA-Solar.com). The maximum
output power of the AC sources in a stand-alone grid must be observed (see the operating manual of the
SunnyIsland).
For a multicluster system with increased self-consumption and battery-backup function, the connected PV system must
be suitable for both stand-alone mode and utility grid operation (see the planning guidelines
"SMAFlexibleStorageSystem with Battery Backup Function" at www.SMA-Solar.com). The maximum output power of
the PV system depends on the installation site (see Section3.4.3, page20).
DC charge controllers may not be included in a multicluster system connected to the utility grid.
With the internal measuring device of the Multicluster-Box, the multicluster system detects the electricity fed into and
purchased from the grid at the grid connection point of the Grid-Connect-Box. The internal measuring device of the
Multicluster-Box does not replace the energy meter of the electric utility company.

DANGER
Danger to life due to electric shock in case of overvoltages and unsuitable loads
Overvoltages of up to 1500V can occur in the stand-alone grid and in the battery-backup grid. If the loads are not
suitable for these overvoltages or are not safe to operate, a voltage that poses a danger to life may be present on
accessible parts or cables. Touching live parts and cables results in death or lethal injuries due to electric shock.
• Only connect loads that have a CE, RCM or UL designation. These loads are suitable for overvoltages of up to
1500V.
• Operate the loads only when they are technically faultless and in an operationally safe state.
• Check the loads regularly for visible damage.
DANGER
Danger to life due to electric shock when operating a damaged product
Operating a damaged product can lead to hazardous situations since high voltages can be present on accessible
product parts. Touching live parts and cables results in death or lethal injuries due to electric shock.
• Only operate the system when it is in a flawless technical condition and safe to operate.
• Check the system regularly for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the product.
WARNING

2 Safety SMA Solar Technology AG
System DescriptionSI44M-80H-13-MC-IA-en-1010
WARNING
Danger to life from electric shock due to circuit breakers that cannot be tripped
In off-grid systems and battery-backup systems, the SunnyIsland can only trip circuit breakers up to a certain
tripping characteristic. Circuit breakers with a higher operating current cannot be tripped. Under fault conditions, a
voltage that poses a danger to life may be present on accessible parts for several seconds. Touching live
components can result in death or serious injury due to electric shock.
• SI6.0H-13 and SI8.0H-13: Check whether a circuit breaker has a higher trip characteristic than B16 (B16A) or
C6 (C6A).
• If a circuit breaker has a higher trip characteristic than the specified circuit breakers that can be tripped, you
should also install a residual-current device of type A.
WARNING
Risk of crushing injuries due to moving PV array parts
A generator can be started automatically by the SunnyIsland. Moving parts in the PV array can crush or sever
body parts.
• Operate the generator only with the specified safety equipment.
• Carry out all work on the generator in accordance with the manufacturer's specifications.
CAUTION
Risk of burns due to short-circuit currents on the disconnected inverter
The capacitors in the DC input area of the inverter store energy. After the battery is isolated from the inverter,
battery voltage is still temporarily present at the DC terminal. A short circuit at the DC terminal of the inverter can
lead to burns and may damage the inverter.
• Wait 15minutes before performing any work at the DC terminal or on the DC cables. This allows the
capacitors to discharge.
CAUTION
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Mount the inverter in such a way that it cannot be touched inadvertently during operation.
NOTICE
Damage to the system due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the system and impair its functionality.
• Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
• Do not open the product during a dust storm or precipitation.
NOTICE
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.
• Ground yourself before touching any component.
