SMA’s next generation of Sunny Island inverters combines the most advanced technology used in
our Sunny Boys with an outstanding feature set for off-grid PV applications.

The new Sunny Island 5048U has incredible surge capabilities and excellent AC output
characteristics. Each unit provides a very clean and stable 120 VAC output. Multiple units can be
used together for single-phase, split-phase or three-phase applications.

The Sunny Island also features the unique ability to facilitate AC coupling of all power generation
sources. This makes for efficient use of available AC power and greatly simplifies system
expansion.

The Sunny Island 5048U helps to optimize the overall life of the batteries through its advanced
battery management system.  It can also be utilized as a back-up system in grid-tied applications.  
Its seamless transfer allows existing Sunny Boy inverters to be utilized during daytime grid
outages.  The Sunny Island 5048U is an extremely robust and sophisticated unit providing both off-
grid and backup users with the highest quality available in the industry today.

Features:

  • Certified to the new UL 1741 / UL 1998 standards
  • 5-year warranty
  • Suitable for systems from 3 kW to 26 kW
  • AC coupling of all energy sources
  • DC coupling with optional equipment
  • 1, 3 and split-phase, connectable in parallel
  • Excellent overload characteristics for motor starting
  • Long battery service life due to optimum battery management system
  • Memory card
