SMA-SUNNY-Sunny Island SI6048-US-10 6,000 Watt 48 Volts DC 120 Volts AC Inverter

Reduce costs across your entire residential business model

SMA's new generation of Sunny Island inverters combines the most advanced technology used in the Sunny Boys with an outstanding feature set for off-grid PV applications. The new Sunny Island 6048-US 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 6048-US 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 backup system in grid-tied applications. Its seamless transfer allows existing Sunny Boy inverters to be utilized during daytime grid outages. The Sunny Island 6048-US is an extremely robust and sophisticated unit providing both off-grid and backup users with the highest quality available in the industry today.


Sunny Island 6048-US

SMA Sunny Island inverters are based on the same proven inverter technology the brand is known for. The Sunny Island 6048-US is an off-grid inverter boasting an impressive 96% maximum efficiency and is a complete power system capable of handling critical loads as well as intelligently managing your batteries.

  • 96% efficiency
  • Able to control connected diesel generators
  • Expandable to power up to 100 Kw
  • Intelligent charge control to extend battery life
  • Perfect for off-grid or grid backup systems

Up to 12 Sunny Island units can be connected together to create an off-grid system up to 100kW providing continuous reliable power to your home. Combining the SI 6048-US with a generator allows for back-up battery charging.

When a Sunny Island unit is coupled with a Sunny Boy grid-tie inverter the system becomes an AC coupled system, allowing your PV array to power your loads, charge your battery bank, and feed excess power back to the grid.
