Discover an ESY battery designed to transform the way homes manage renewable energy. With a focus on quality and reliability, this premium home energy storage delivers smart management and greater energy independence for residential homes.
Launched in January 2023, the HM5/6 series reflects ESY Sunhome’s focus on delivering reliable and innovative energy solutions. Developed by a leading supplier of battery management systems headquartered in Shenzhen, the HM6 series is an all-in-one energy storage system that combines advanced battery technology, an integrated 6 kW hybrid inverter and intelligent software to support efficient energy use.
The 5kW or 6kW hybrid inverter plays a crucial role in converting photovoltaic solar energy into usable power and managing the flow of energy between solar panels, batteries, and the grid. This ensures optimal performance and compatibility with both single-phase and three-phase power systems commonly found in Australia.
When grid power drops during a blackout, the system responds instantly to keep your home running. Designed for residential resilience, it supports uninterrupted performance during outages.
Energy independence isn’t just about savings — it’s about reliability. The home battery delivers controlled, stable power even during unexpected grid interruptions.
Designed for performance, safety, and long-term reliability in Australian conditions.
With stackable battery modules, the system can expand to meet growing demands, ensuring a future-proof solution that adapts to your lifestyle. This scalability makes it a versatile choice for any home.
ESY Sunhome utilises high-voltage lithium iron phosphate (LiFePO₄) battery technology, known for its enhanced safety, longevity, and stable performance across the energy industry.
The battery enclosure is rated IP66, providing strong protection against dust and water ingress for reliable operation in a wide range of installation environments.
High-voltage battery storage with scalable capacity, solar compatibility, and real-time smart monitoring for Australian homes.
Monitor your system, optimise usage, and stay in control day and night.
The HM6 battery starts at 5.12kWh and expands up to 30.72kWh with additional modules. This storage system designed to provide flexible usable capacity for growing households.
Engineered for compatibility with existing solar systems, the battery supports both single-phase and three-phase power setups. The integrated 6kW inverter works seamlessly with solar panels and battery storage.
The ESY Sunhome App provides real-time monitoring of battery performance, solar production, and grid consumption, allowing users to manage energy usage efficiently.
