Multicluster-Boxes

For easy set-up of off-grid and hybrid systems

Set up large off-grid systems with minimum effort: the new Multicluster-Boxes for the Sunny Island 5048 are the ideal solution for the easy installation of island and hybrid systems from 30 up to 300 kW. For this, 2 to 12 three-phase clusters, each consisting of three Sunny Island inverters, are connected in parallel. The Multicluster-Box was developed specially for these systems as the AC main distribution unit with integrated generator contactor and load-shedding contactors. To simplify installation, all Multicluster- Boxes are completely wired and fitted with a main connector for PV or wind generators (ex works). All communication wiring required for the installation is contained in the scoop of delivery.
