If you’re looking to add a battery to your solar system in Hobart, Bellerive or Launceston, the iStore battery offers a practical and efficient storage solution. Known for its simplicity, safety and strong performance, it helps you store excess solar power and use it when you need it most — during the evening, in cloudy conditions, or when the grid goes down.
Whether you’re upgrading an existing system or planning a full solar and battery setup, the iStore battery integrates smoothly with a range of inverters and performs well year-round, making it a great fit for homes across southern Tasmania.
Tasmania’s changing weather, shorter winter days and rising electricity costs make energy storage more important than ever. The iStore battery system gives Hobart, Bellerive and Launceston homeowners the ability to store their solar power and use it later — whether that’s in the evening, during cloudy stretches, or during a grid outage.
iStore’s modular design means you can size your battery to suit your household needs, while their energy-efficient heat pumps and pool heating solutions offer further savings by reducing your grid dependence throughout the year. It’s a complete approach to smarter, more affordable home energy.
The iStore solar battery brings together practical design, reliable performance, and flexible storage — making it a smart option for homes in Hobart, Bellerive and Launceston. Whether you’re looking to maximise your solar usage or prepare for outages, iStore batteries are built to deliver day-to-day value and long-term energy savings.
iStore uses Lithium Iron Phosphate (LFP) chemistry, known for its thermal stability and long cycle life. Four layers of in-built protection, including self-extinguishing components, ensure safe operation for years to come.
Store excess solar energy that would otherwise be sent to the grid, and use it later when electricity prices peak — helping you get more value from every kilowatt your system produces.
With total capacity ranging from 5kWh up to 30kWh, iStore batteries can comfortably meet the daily energy needs of the average Tasmanian household — and scale to suit larger homes or higher usage patterns.
Pair your system with the optional iStore Backup Box to provide power to key appliances and circuits during a grid outage — ideal for homes dealing with Tasmania’s unpredictable weather.
iStore batteries integrate easily with iStore hybrid inverters, available in both single and three-phase. They’re designed to suit a wide range of home energy profiles and solar setups.
Rather than installing a whole new battery to increase storage, iStore’s modular system lets you add extra battery blocks as needed — up to three modules per energy management system and two EMS units per inverter. That means fewer upfront costs, smarter sizing, and efficient use of space.
Wall or floor mount options are available, with a slim 15cm design that makes installation simple, even in tight spaces or existing garages.
Unlike many batteries that restrict usage to 80–90% of stored energy, iStore gives you 100% usable capacity — and with built-in optimisation, you can unlock even greater efficiency across its lifespan.
At Marshall Solar & Energy, we’ve worked with a wide range of battery systems across southern Tasmania — from family homes in Hobart to modern builds in Launceston and energy-conscious upgrades in Bellerive. The iStore battery has proven to be a reliable option for households looking for a straightforward, flexible way to store solar energy.
Its modular design makes it easy to match your storage to your energy use, whether you’re running a small system or planning for future upgrades. The system is well-suited to Tasmania’s cooler climate and changing seasonal daylight, helping you capture more of your solar during the day and use it when it counts.
With smart monitoring and simple integration, iStore makes managing your home energy easy — and if you ever need support, our local team is ready to help.
