The Sunny Island battery inverter supports a wide range of on and off-grid installations with compelling product features— from operation in off-grid areas to home energy management. Users can benefit from SMA’s experience in having more than 70,000 Sunny Island inverters installed worldwide. Thanks to its integrated web interface and standard interfaces WLAN and Ethernet, the Sunny Island 4.4M/6.0H/8.0H can be easily configured and monitored via smartphone or tablet. And being a core element in the SMA Flexible Storage System, the Sunny Island temporarily stores self-generated power thus making it possible to use solar power around-the-clock. Its high protection class, wide temperature range and exceptional overload capacity always provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations. The Sunny Island is the ultimate all-purpose solution—and includes a 10-year warranty
