1. Modular & Expandable Design
ESY Sunhome batteries are designed with flexibility in mind. Each module offers around 5.12 kWh of storage, and the system can be expanded by stacking additional modules, allowing homeowners to scale capacity from 5 kWh up to 30 kWh. This modular setup ensures that households can start with a smaller investment and expand later as their energy needs grow.

2. Safe & Reliable Performance
Built with Lithium Iron Phosphate (LiFePO₄) chemistry, ESY Sunhome batteries provide superior thermal stability, enhanced safety, and reduced risk of overheating compared to traditional lithium-ion technologies. With an IP66 rating, the battery units are fully dustproof and resistant to heavy water exposure, making them durable and reliable in all Australian outdoor conditions.

3. High Efficiency & Strong Power Output
These batteries are engineered for maximum energy utilisation with a usable depth of discharge (DoD) of up to 95%. This means more of the stored energy can be accessed and used every day, translating into greater savings. They also support high charge and discharge rates, ensuring they can meet demanding household loads, handle peak power requirements, and recharge quickly during solar generation hours.

4. Long Life & Warranty Assurance
ESY Sunhome batteries are built for long-term use, with 6,000 charge cycles not 6000-10000 depending on usage conditions. This translates to more than a decade of dependable performance. To back this reliability, they are supported by a 10-year manufacturer’s warranty, offering homeowners confidence and peace of mind in their investment.

5. Smart, Hybrid & Backup Ready
Most ESY Sunhome systems are integrated with hybrid inverters, making them “all-in-one” solutions that simplify installation and system design. They feature fast backup switchover times (milliseconds) during grid outages, ensuring uninterrupted supply for essential household appliances. Paired with the Smartify CloudApp, users can monitor energy production, storage, and consumption in real time, while also customising modes like peak shaving, off-grid, or backup operation.

6. Flexible Applications Across Homes

ESY Sunhome batteries are suitable for single-phase only with HM5 and HM6 series of inverter, making them versatile enough for small suburban homes, larger properties, or even light commercial sites. Their quiet operation and wide operating temperature range (from sub-zero cold to high heat) make them adaptable to diverse Australian environments and ideal for installation close to living areas without causing disturbance.
