The Sunny Island 6.0H / 8.0H is the all-rounder for high performance on-grid and off-grid solutions. This system is a key element in the SMA Flexible Storage System for both new and existing photovoltaic systems. The Sunny Island system works by storing your self-generated solar energy and, combined with the Sunny Home Manager 2.0, allows you to manage your energy consumption intelligently. 

  • 6kW to 8kW battery controller
  • Supports a wide range of applications
  • £3,000.00 exc. VAT

The Sunny Island 6.0H / 8.0H provides fantastic flexibility when combined with other quipment, allowing the system configuration to be customised to precisely meet the specific power requirements your situation requires. 

The system's flexibilty enables it to be retrofitted for use in both single phase and triple phase systems and, should you requirements increase at any time, it allows you to change the size of the system at any time, using SMA Multicluster Technology

Don't worry about whether it will run with your chosen battery either. The Sunny Island is fully compatible with all lead-acid batteries, as well as the majority of well known brands of lithium-ion batteries!


In the SMA smart home, the Sunny Island, combined with their Sunny Home Manager 2.0, takes full responsibilty of everything. Using intelligent management between your PV system, appliances, storage systems and also regulating the flow of energy throughout the whole system. 

You can get a comprehensive visualisation of how the system is performing using the Sunny Portal. Although, this isn't necessary, as the system takes care of everything automatically. It even uses a forcast based procedure, so it knows when the best times to charge are, allowing it to charge your batteries without you even noticing!


We can definitely recommend this system if it's durability you're worried about. It's been built to the highest standards and SMA claim that it is impervious to fine desert sand, high humidity in rainforests and salty mist in coastal regions, as well as being able to withstand significant temperature fluctuations! The system also acheived an ingress protection rating of IP54. These high build quality standards allow you to position the SMA Sunny Island wherever suits you, be that in the relative safety of your garage, or on the outide of your home.
