Sunny Island-4548-US / 6048-US

Here you will find comprehensive system solutions for an autonomous power supply. System components used in such applications include, for instance, Sunny Island inverters in the role of grid and battery manager, inverters for PV, small wind turbine and fuel cell systems and the appropriate monitoring products.
And even for grid-tie batteries, SMA's Sunny Backup system is a tried and tested, scalable product solution which includes reliable protection against grid failures.

SUNNY ISLAND - The flexible System manager

The Sunny Islands offer you first class possibilities in the installation of self-sufficient energy systems. In conjunction with a battery pack the devices form a self-sufficient AC voltage grid, which meets with the highest of quality standards.

In the Sunny Island System, electricity generators and consumers are integrated in equal measure. PV and wind energy systems, diesel devices, water or CHP (Combined Heat and Power) can be coupled on the AC side just as conventional 230 Volt consumers.

The Efficient Island Manager: Now with 20 Percent More Power

In the development of the new Sunny Island inverters 4548-US and 6048-US, their efficiency was in particular was optimized. Expanding on the proven technology of Sunny Island 5048-US, they can reach the maximum efficiency level of over 96 % as well as a weighted CEC efficiency level of 94.5 %. This saves diesel costs and enables a smaller dimensioning of PV plants. The new devices for the US market can be used with the SMA multicluster technology for systems with a capacity of up to 100 kW.
