2 Safety
2.1 Intended Use
The Multicluster Box is a component of the SMA multicluster technology for off-grid systems. The
Multicluster Box is a main AC distribution board to which you can connect up to twelve three-phase
clusters. Each cluster consists of three Sunny Island inverters of the same device type with parallel
DC-side connection.
Figure1: Circuitry principle
Connection requirements
The Multicluster Box is designed for connection to TN systems. The Multicluster Box must
be grounded prior to commissioning (see Section7.9, page33).
2 Safety SMA Solar Technology AG
8 MC_BOX_36-BE-en-20 Operating Manual
Do not exceed the maximum AC connection power of the Multicluster Box.
Only operate the Multicluster Box in conjunction with Sunny Island inverters of type Sunny Island
5048 / 6.0H / 8.0H. Always take the maximum AC connection power and the permitted
Sunny Island combinations into account.
Permitted Sunny Island combinations
Α Only Sunny Island inverters of the same device type are permitted to operate in one cluster.
Α Different clusters may be equipped with different device types.
The Multicluster Box is designed for use at altitudes of up to 2,000 m above mean sea level. If you
wish to use the Multicluster Box at altitudes above 2,000 m, contact SMA Solar Technology AG
(see Section13 "Contact", page44).
The product is designed for indoor use only.
The product is designed for EMC environment A* . In EMC environment B*, the product can cause
undesired electromagnetic interference.
Α If the product is operated in EMC environment B, take protective measures against
electromagnetic interference in accordance with the locally applicable standards and
directives.

2.3 Safety Precautions
This section contains safety precautions that must be observed at all times when working on or with
the product.
To prevent personal injury or property damage and to ensure long-term operation of the product, read
this section carefully and follow all safety precautions at all times.
Danger to life due to electric shock
High voltages are present in the Multicluster Box. Touching live components results in death or
serious injury due to electric shock.
Α Disconnect the Multicluster Box from all voltage sources before carrying out any work.
Α Switch off all loads.
Α Switch off the master of the main cluster.
Α Disconnect all Sunny Island inverters in the Multicluster Box and secure against
reconnection.
Α Disconnect the PV main distribution board and secure against reconnection.
Α Shut down the generator and secure against unintentional reconnection.
