2 Safety
2.1 Appropriate usage
The Multicluster Box is a component of the SMA Multicluster technology. It is used to set up stand-
alone grids with several Sunny Island 5048. The Multicluster Box is an AC main distributor. You can
connect the Sunny Island devices, the loads, the generator or the grid and a further generator to the
Multicluster Box, e.g. a PV plant or a small wind turbine system.
Connection requirements
The Multicluster Box is designed for connection to TN grids. The Multicluster Box must be
grounded before commissioning (see section 5.3.5”Grounding the Sunny Island
Multicluster System” (page27)).

Principle of the SMA Multicluster technology with an MC-BOX-36.3
You may operate the Multicluster Box only in conjunction with off-grid inverters of the type
Sunny Island 5048.
Do not exceed the maximum AC connection power of the Multicluster Box of 300 kW each at an
ambient temperature of 25 °C for PV plants, generator and loads.
The Multicluster Box is designed for use at altitudes of up to 2 000 m above sea level. If you wish to
use the Multicluster Box at altitudes above 2 000 m, contact SMA Solar Technology AG (see section
11”Contact” (page40)).
