The SMA Multicluster System 12 is suitable for operation on the utility grid as well. In Germany, it complies with the applicable conditions for connection to the low-voltage grid of VDE-ARN 4105: With the battery inverters Sunny Island 6.0H or 8.0H and the NA-Box 12, commercial self-consumption and battery-backup systems of up to 100 kilowatts can be set up.
On an international scale, the Grid-Connect-Box 12 can be used to form self-consumption and battery-backup systems with an output of up to 138 kilowatts. The new Multicluster-Box 12 is suitable for TN- and TT-grids thanks to the integrated grounding contactor.
In areas with very unstable utility grids, a diesel generator can also be connected. For off-grid regions, the SMA Multicluster-Box 12 allows powerful solar off-grid systems with up to 138 kilowatts to be set up – ideal for commercial enterprises and village power supplies in rural regions.
