SMA Battery Storage Systems

See our reviews

SMA Battery storage and battery back-up systems enable you to store surplus electricity generated during the day to use at night or when there is a demand for the power, reducing your electricity costs even further. If you produce more energy than you can use and store you can still feed the surplus into the grid. Another perk of a battery back-up system is that in the event of a power cut your battery system will continue to feed your property and also keep your solar PV system generating.

Installing a battery storage system will allow you to monitor, optimise and manage exactly how you use the power you have generated.

Sunny Boy 3600 Smart Energy

Sunny Boy 3600 Smart Energy – The Perfect Combination of PV Inverter and Battery

  • 6kW PV inverter
  • 2kWh integrated battery
  • Save up to 50% on electricity bills!
  • 5 year warranty

The new Sunny Boy 3600 Smart Energy system is the perfect storage solution for your household PV applications. it combines a modern photovoltaic inverter with an integrated 2kWh battery, which not only optimises increased self-consumption, but also makes using your home-generated solar power possible virtually around the clock.

With its integrated battery, the Sunny Boy Smart Energy offers two advantages. Not only does it provide a sensible way to increase self-consumption, but it also makes it easy to use self-produced solar power after the sun goes down.

  • Significantly reduced initial investment thanks to an application-oriented battery capacity of 2 kWh
  • No need to design the battery system – so no battery expertise is required
  • Quick and easy wall mounting
  • Efficient charge management and load control
  • Maximized reliability through lithium-ion cells

Together with the Sunny Home Manager, the Sunny Boy Smart Energy is the central component of the SMA Integrated Storage System. It offers an incredibly easy path to greater independence as part of the SMA Smart Home intelligent energy management.

  • Approximately 52 percent less electricity purchased from electric utility companies
  • Self-consumption rate increased from 30 percent to typically 55 percent
  • Usage of solar power possible nearly 24 hours a day
  • Outstanding efficiency in terms of power conversion and temporary power storage

Sunny Island 6.0H / 8.0H

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
  • 5 year warranty
  • Batteries sold separately


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

The system’s flexibility enables it to be retrofitted for use in both single phase and triple phase systems and, should your 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 responsibility 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 forecast 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 achieved 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 outside of your home.
