Can be used flexibly in private homes and commercial enterprises
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
Self-consumption systemsin your own home
As a core element in the SMA Flexible Storage System, the Sunny Island temporarily stores the solar power from the system. It automatically controls the power consumption in the home in conjunction with the intelligent SunnyHomeManager 2.0 energy manager. Solar power can then be used 24 hours a day both in your home and in commercial enterprises.
Self-consumption systemsfor commercial enterprises
The Sunny Island provides an efficient, safe and consistent electricity supply in commercial applications such as agricultural holdings, hotels, supermarkets and schools. It balances out load and demand peaks and takes on electricity supply during grid failures.
Off-grid systems
Its high protection class, wide temperature range and exceptional overload capacity always provide the kind of security in the electricity supply that is needed for off-grid use. Intelligent load and energy management ensures operation even in critical situations and allows any appliance to be switched on even in the event of high inrush currents or harsh ambient conditions.
Always a reliable electricity supply
The Sunny Island runs reliably under even the most extreme conditions without compromising its efficiency.
Exceptionally high overload capacity ensures a safe electricity supply, even in critical situations
IP54 for operation even in extreme environments
Possible system configurations with Sunny Island 4.4M / 6.0H / 8.0M
Single, single-phaseSI 4.4M, SI 6.0H and SI 8.0H for systems from 1kW to 8kW.
Single cluster, single-phase
Up to three SI 6.0H or SI 8.0H inverters can be coupled in parallel in one phase for system from 3kW to 24kW.
Single cluster, three-phaseThree SI 4.4M, SI 6.0H or SI 8.0H battery inverters can be connected each one to one phase to build 3-phase systems from 5kW to 24kW.
