iStore Solar Battery Systems – Smart, Scalable Storage for Smarter Solar

Looking for a powerful, flexible battery to pair with your solar system? iStore Battery Systems deliver reliable energy storage, seamless integration with hybrid inverters, and exceptional scalability — all designed with Australian homes in mind.

At Greenbank Solar, we recommend iStore batteries for homeowners who want to take control of their energy, protect themselves against rising power bills, and enjoy the security of backup power — all while making the most of their solar production.

🔋 What Is the iStore Solar Battery System?

The iStore battery system is a modular lithium iron phosphate (LiFePO₄) energy storage unit, with each module providing 5kWh of usable storage. Up to three units can be stacked together, giving you 15kWh of storage per stack. Even better — you can run two stacks per iStore inverter, offering a massive 30kWh of energy storage per system.

This flexibility makes the iStore battery ideal for both standard households and high-usage homes wanting long-term energy independence.

🔧 Designed to Work Seamlessly with iStore Inverters

iStore Solar battery systems are designed to pair perfectly with iStore Hybrid Inverters — creating a streamlined, all-in-one solar + storage solution.

One standout advantage of the iStore hybrid inverter is its ability to support solar panel arrays up to 2.5x its rated capacity. That means a 5kW inverter can support a 12.5kW solar array, boosting energy generation and helping your batteries charge faster — even in winter or cloudy conditions.

This powerful inverter-battery combo allows for:

  • Faster battery charging

  • Greater energy self-sufficiency

  • Maximised feed-in when the battery is full

  • Optimal returns on larger rooftop systems
