2 Safety
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.
Figure 1: Circuitry principle
Connection requirements
The Multicluster Box is designed for connection to TN systems. The Multicluster Box must be grounded prior to commissioning (see Section 7.9, page 33).

6 Installation
Requirements for the mounting location:
Danger to life due to fire or explosion
Despite careful construction, electronic devices can cause fires if they are not installed properly. This may result in death or serious injury.
•Do not install the Multicluster Box on flammable construction materials.
•Do not store any highly flammable materials or products in the vicinity of the Multicluster Box.
•Do not install the Multicluster Box in potentially explosive areas.
Optimum mounting location
The ambient temperature of the Multicluster Box influences the tripping threshold of the circuit breakers for the Sunny Island inverters. The higher the temperature, the earlier the circuit breakers will trip. At high ambient temperatures, the derating function of the Sunny Island inverters inhibits premature tripping of the circuit breakers.
•To ensure optimum operation, mount and install the Multicluster Box and the Sunny Island inverters at the same location.
A firm, even foundation, e.g., a concrete surface, must be available for mounting.
The mounting location must be suitable for the weight and dimensions of the Multicluster Box (see Section 12 "Technical Data", page 41).
The mounting location must be clear and safely accessible at all times without any need for auxiliary equipment.
The mounting location must not hinder access to disconnection devices.
All local requirements concerning minimum passage widths and escape routes must be observed.
Climatic conditions must be met (see Section 12 "Technical Data", page 41).
The mounting location must be below 2,000 m above MSL. For altitudes over 2,000 m above MSL, contact the SMA Service Line.
