SUNNY ISLAND SI 4.4 M-13 battery inverter

The custom-fit solution for on-grid and off-grid with WLAN

The Sunny Island 4.4 M-13 support a wide range of on-grid and off-grid applications, and both systems have a number of compelling product features. Users benefit from SMA’s over 25 years of experience with battery inverter technology. Its high protection class, wide temperature range and overload capacity provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations. And being a core element in the SMA Flexible Storage System for new and existing PV systems, the Sunny Island system stores generated solar power and works with the Sunny Home Manager to intelligently manage home energy consumption. The new Sunny Island 4.4 M system are the perfect product solutions for stand-alone and grid-connected systems in a power output range of up to 13 kW.

Its high protection class, wide temperature range and exceptional overload capacity always provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations.


  • For self-consumption systems, battery backup systems and off-gridsystems
  • For single- and three-phase systems from 3 to 13 kW
  • All lead-acid batteries and many lithium-ion batteries can be used


  • Maximum efficiency greater than 95 %
  • High efficiency of overall system
  • Easy commissioning and installation

Safe and reliable

  • Proven safety thanks to external certification
  • Long battery life thanks to intelligent battery management
  • Reliable operation thanks to high overload capacity
