SMA Sunny Island 4.4M



Sunny Island 3.0M / 4.4M

More durable than its predecessors: The new Sunny Island impresses with its high protection class and wide temperature range. Moisture, dust and temperature fluctuations won’t impair its operation, even after 20 years. Thanks to OptiCool, there’s no need to compromise when it comes to overload capacity and economic viability. And there’s more: OptiPower, the intelligent load and energy management system, ensures operation even in critical situations. OptiUse makes installation, commissioning and daily use easier than ever with automatic rotary field detection, an optimized quick configuration guide and intuitive operation. And the intelligent OptiBat battery management system automatically controls the most important charging and discharging procedures, which extends the service life of sensitive energy storage. Sunny Island is a truly comprehensive package for a worry-free, reliable and self-sufficient electricity supply. Sunny Island 3.0 and 4.4 are ideal for on-grid and off-grid applications when using small systems with a lower power range.
