SUNNY ISLAND 3324 / 4248 / 4248-US Simple • For systems from 2 to 5 kW • AC and DC coupling • Simple installation Durable • Extreme overload capability • 5-year SMA Warranty Efficient • High efficiency • Excellent price-performance ratio SUNNY ISLAND 3324 / 4248 / 4248-US Stand-alone grids easier than ever Easy installation, safe operation and outstanding price-performance ratio: the Sunny Island 3324 and 4248 battery inverters are especially suitable for use in small and mid-sized stand-alone grids. The Sunny Island 4248-US model is available for countries with voltage systems compatible with the U.S. standard. The devices guarantee a reliable and high-quality power supply. Due to their outstanding overload capabilities and the fact that they are designed to withstand high ambient tempera- tures, these devices can be used under extreme weather conditions.
