Even more economical

With the new generation of devices, installing the proven Sunny Island charger inverter is even simpler and more economical. Whether within your own home or for industrial applications. On the public power grid or in areas far from the grid.

Sunny Island has already been installed more than 120,000 times worldwide. With the new generation, installers and plant operators benefit from an even more user-friendly charger inverter.

• Lower system costs due to fewer components
• Faster installation and commissioning thanks to a simple user interface
• Extended warranty period: 10 years

Interactif dans tous les domaines


Interactive in all areas

Thanks to the integrated web interface and standard WLAN and Ethernet interfaces, the Sunny Island is now easy to configure and monitor from a smartphone or tablet.

• Use of standard Ethernet and WLAN interfaces
• Webconnect for quick and easy installation monitoring via Sunny Portal/Sunny Places
• Local monitoring via web interface
• Optimized data logging for maximum transparency, even without permanent online access

Flexible implementation in residential and business

Sunny Island is particularly flexible, whether used in remote areas of the grid or for energy management in the private or industrial sector. It offers planners maximum freedom in terms of system size and type, battery and energy production mode. For self-consumption systems, backup power systems and networks in isolated sites.

• Possibility of subsequent equipment and modular extension for single-phase and three-phase systems from 1 to 30 kilowatts
• For all lead-acid batteries and more than 20 different lithium-ion batteries
• Scalable with SMA's multicluster technology for systems from 20 to 300 kilowatts

Un approvisionnement énergétique fiable à tout momentReliable energy supply at all times

• Sunny Island operates reliably even in the most extreme conditions, without loss of profitability.
• Extremely high overload capacity ensures energy supply even in critical situations
• IP54 for operation even in extreme conditions
