SMA, Sunny Island 4548 battery inverter, 4500W, 120VAC, 60Hz, 56A Transfer, 48VDC, Sinewave, 100A Charger, 5 Yr Warr, with BTS, SI4548-US-10 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 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 to 100 kW in size. The Sunny Island inverters are bi-directional battery-based inverter/chargers that can be used completely off-grid, or for battery backup in grid-tie systems either with charge controllers or with grid-tie inverters using AC coupling. The Sunny Island includes sine-wave output power at 120 VAC only. Two or four Sunny Island inverters can be stacked for 120/240 VAC input and output. Three Sunny Islands can also be stacked for a 120/208 VAC three phase input and output. They have low idle losses as well as a 100 A battery charger, and a battery disconnect. State-of-charge metering helps with battery management to ensure maximum battery life. |
