SUNNY ISLAND 5048U

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, splitphase 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 also helps to optimize the overall life of the batteries through its advanced battery management system. The Sunny Island can also be utilized as a back-up system in gridtied 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.
