The Sunny Island is a bidirectional inverter (battery inverter and battery charger) for off-grid systems. The Sunny Island supplies loads on the stand-alone grid side and charges the batteries with the energy from grid-feeding units connected on the AC side.

SMA has an extensive range of products, which offers the right inverters for all module types and plant sizes; for small residential systems as well as large scale plants, grid-connected installations as well as stand-alone and backup systems all over the world. Plant monitoring and visualization products as well as energy management solutions complete the portfolio.

Commissioning within minutes: the Sunny Island 5048 makes it possible. All required operational settings can be made quickly and easily in just a few steps. The Sunny Island 5048 is flexible in its application, extendable and takes on all control processes.

Its first-class battery management ensures maximum battery lifetime. In addition, the device features an impressive high efficiency, ergonomic die-cast aluminum enclosure and an OptiCool active cooling system.

As the central unit of a stand-alone power supply system, battery inverters have many different functions and are often difficult to configure. Yet the Sunny Island 5048 from SMA shows that simplicity is also possible. Fit for systems of 3 to 300 kW, it can be commissioned in a matter of a few minutes. All settings required for operation can be made quickly and simply.

The Sunny Island 5048 is flexible in its application, extendable and takes on all control processes. Its first-class battery management ensures the maximum service life of the batteries protecting your investment. In addition, the Sunny Island 5048 features many of the innovative product characteristics which made SMA a winner in a test carried out by the German product standards institute “Stiftung Warentest”: high efficiency, an ergonomic aluminum housing and its OptiCool ventilation system.
