Together with the battery unit, the stand-alone inverter Sunny Island creates a standard AC voltage grid into which all components, from electrical appliances to electricity generators, can be integrated. With this AC coupling and the Sunny Island as its system manager, SMA has developed the technological solution for energy supply in remote areas which are far away from the mains grid, or for emergency power supply in unstable grids. For the first time, PV systems, wind turbines, diesel generators, hydroelectric or combined heat and power plants can now be coupled on the AC side along with 230 V loads, eliminating the need for expensive DC cabling and providing maximum flexibility. This makes it possible to adapt a stand-alone grid of this kind to increasing demands, quickly and without technical complexity. With SMAs technology it is possible toprovide electricity to a large proportion of the 1.6 billion people who do not have access to it today. New Sunny Island products: the Sunny Island 2224 extend the product range for the lower power sector. The new devices do not only include the well-known features from the big brother Sunny Island 5048. A lower weight and a reduced size make the new inverters even easier to handle and install. The high protection class IP54 and the Sunny Remote Control (SRC-1) give you full flexibility for the installation location. The integrated data storage and update feature via SD card result in additional user and service friendliness. Easy to use technology at its best: the unbeatable combination for off-grid systems up to 9 kilowatts. The Sunny Island 5048 is flexible and expandable, takes on all control processes in an off-grid system, and ensures a continuous power supply. The extended battery management allows a very precise determination of the batterys state of charge. This enables improved utilization of the battery capacity. Intelligent temperature management and excellent overload characteristics make the Sunny Island 5048 particularly suitable for use in extreme conditions.

The SMA Sunny Island Bundles are sets which include several interters with different configurations. Sunny Island 5048 Bundle 2 - also 3-phase system possible.

Install large off-grid systems with minimum efforts: the new Multicluster-Boxes for the Sunny Island 5048 are the ideal solution for the easy installation of island and hybrid systems from 30 up to 110 kW. Two up to four 3-phase clusters each consisting of 3 Sunny Islands are connected in parallel. The Multicluster-Box is specially designed for this task as AC distribution with integrated generator and load shedding contactor. We made the installation as easy as possible for you: all wiring is ready for operation and the Multicluster-Boxes are equipped with a main connection for PV or wind energy systems for the desired power range. The communication cables necessary for the installation are all included in delivery.
