Sunny Island 4548-US | The efficient off-grid manager
The SMA Sunny Island 4548-US and 6048-US inverters are based on proven off-grid technology and feature industry leading power output. A maximum efficiency of 96 percent ensures peak production, which results in reduced diesel usage in rural communities. More flexible sizing allows for simplified system planning. And, with multicluster technology, up to 12 Sunny Islands can be integrated into off-grid power systems up 110 kW in size.
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.
