SMA Sunny Island SI6048-US-10 5.75kW 48VDC 120VAC Battery Inverter

SMA Battery Charger / Inverter Sunny Island SI6048-US-10 5.75kW 48VDC 120VAC 

The SMA Sunny Island SI6048-US-10 is a powerful inverter/charger. This bi-directional unit is built for off-grid or grid-tie backup systems. It provides sine-wave AC power at 120 VAC only. You can stack two or four units for 120/240 VAC output. Three units can stack for 120/208 VAC three-phase output. These inverters have low idle losses. They include a built-in 100 A battery charger and disconnect. State-of-charge metering helps manage the battery for maximum life.

System Flexibility and Charging

For off-grid use, the Sunny Island works with standard charge controls. It can communicate with the MidNite Classic using the MNSICOMM box. It also runs AC-coupled systems with Sunny Boy inverters. The frequency shift algorithm manages charging to prevent battery overcharge. A generator can be connected to the AC input for backup and charging.

For grid-tied backup, the frequency shift works to cycle the Sunny Boy on and off. This controls the charging of the batteries.
