- Maximum efficiency of 96% with 94.5% CEC efficiency
- Intelligent battery management including state of charge calculation for maximum battery life
- Integrated soft start/generator support
- Versatile - complete for off-grid management as well as grid-tie battery backup/AC Coupling
- Easy set up with the "Quick Configuration Guide"
- Suitable for Sunny Island systems from 4.5 to 100 kW
- Single, 120/240 split-phase and three-phase operation, connectable in parallel, and modularly expandable
- Excellent overload characteristics with 'Opti-cool' active temperature management
- Five Year Standard Warranty
One of the greatest benefits of AC coupling is that it allows virtually any type of power generating device to be connected to the system, i.e. solar, wind, water, even gas or diesel powered generators. It's an easy, clean way to give grid-tie customers the option of having back-up power available during outages. And it provides system designers the opportunity to take advantage of all the resources available to them at a given location. It also allows for easy system expansion by providing a simple solution for integrating future power sources.
The Sunny Island has also been designed for easy expansion. The power provided by the Sunny Island can be increased simply be adding an additional Sunny Island inverter in parallel. AC coupling provides easy system expansion and ensures that over the long term, the system will continue to serve the needs of its users safely and reliably.
SMA Sunny Island 6048-US inverters are high reliability battery based inverters sutable for off-grid or grid-tie systems. A maximum efficiency of 96 percent ensures peak production, When used with multicluster technology, up to 12 Sunny Islands can be integrated into off-grid power systems up 100 kW in size.

The efficient island manager: now with 20 percent more power
The new SMA Sunny Island 4548-US and 6048-US inverters are based on the proven off-grid technology in the Sunny Island 5048-US but now feature 20 percent more power output. A maximum efficiency of 96 percent ensures peak production, which results in reduced diesel usage and makes a smaller dimensioning of the PV array possible. The new Sunny Island with two different power ratings enable more flexible system sizing. And, with multicluster technology, up to 12 Sunny Islands can be integrated into off-grid power systems up 100 kW in size.
