    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.
