Easy setup of powerful off-grid systems

In regions without grid access, powerful off-grid and hybrid systems can be installed based on proven technology: 2 to 12 three-phase clusters, each consisting of 3 Sunny Island inverters, deliver up to 360 kW of output capacity.

To simplify installation, all Multicluster-Boxes are completely wired at the factory and have a dedicated connection interface for generator sets, load distribution and renewable energy systems. This makes them ideal for businesses and for supplying electricity to rural regions, with or without grid access.

Highlights

  • Three power classes, from 20 kW to 300 kW
  • Integrated AC distribution for Sunny Island, generator and PV
  • Integrated load-shedding contactor
  • Automatic bypass for the PV generator
  • Active anti-islanding and reverse-current monitoring
  • High protection classes, 5-year SMA warranty
