Multicluster-Boxes for SUNNY ISLAND
With the SMA Multicluster-Boxes for Sunny Island battery inverters, both off-grid systems and battery-backup systems* can
be configured easily and cost-efficiently. In regions without grid access, based on proven technology, powerful off-grid and
hybrid systems with 2 to 12 three-phase clusters, each consisting of 3 Sunny Island inverters of up to 360 kilowatts of output
capacity can be installed.
For systems connected to the utility grid, battery-backup systems* with up to 138 kWp can be set up. To simplify installation,
all Multicluster-Boxes are completely wired at the factory and have a dedicated connection interface for generator sets, the
load distribution and renewable energy systems. The Multicluster-Boxes are ideal for use in businesses and to supply electri-
city to rural regions – with or without grid access
