Product Description

Details

The Sunny Island has maximum flexibility, from operation in remote off-grid areas to commercial or home energy management. It gives planners total freedom in the size and type of system, the battery and the type of energy generation. Works with self-consumption systems, battery backup systems and off-grid systems.

  • Ideal for retrofits or modular expansions of single- and three-phase systems in the 1 to 30 kW range.
  • All lead-acid batteries and over 20 different lithium-ion batteries can be used.
  • Can be expanded with SMA Multicluster-Technologie for systems in the 20 to 300 kW range.

With the new generation of devices, the tried-and-tested Sunny Island battery inverters are easier and more affordable to install than ever – both in your home and in commercial applications as well as to the utility grid and in off-grid locations.

Communicative in all areas

  • Thanks to its integrated user interface and standard WLAN and Ethernet interfaces, the Sunny Island can be immediately and easily configured and monitored via smartphones or tablets.

Uses standard Ethernet and WLAN interfaces

  • Web connect for faster and easier PV system monitoring with Sunny Portal / Sunny Places.
  • Local monitoring via web interface.
  • Optimized data logging for maximum transparency, even without continuous online access.
