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.
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.
Start with a single 5.12 kWh LFP module and expand vertically up to 30.72 kWh (6 modules). Each module is self-contained with its own integrated fire suppression, so you only pay for the capacity you need today while keeping future expansion simple.
The HM6 combines a 6 kW single-phase hybrid inverter and battery storage in one sleek, floor-standing unit. It connects directly to new solar arrays or works as an AC-coupled battery retrofitted to existing systems.
A dedicated backup circuit switches to battery power in approximately 20 ms during grid outages. Essential circuits stay live — fridges, lights, internet, and security systems keep running without interruption.
Built-in protection at every level: advanced Battery Management System (BMS), mechanical system lock, secondary protection circuit, overcurrent fuse, and fire suppressant gel inside each module. LiFePO₄ chemistry adds thermal stability with no cobalt.
Engineered for Sydney’s coastal and inland conditions. IP66 ingress protection means full dust sealing and resistance to heavy water jets, whether installed in a garage, carport, or shaded outdoor wall.
The ESY Sunhome App delivers real-time visibility into solar generation, battery state-of-charge, and household consumption. AI-driven insights help optimise charge/discharge cycles based on your usage patterns, weather forecasts, and time-of-use tariffs.
SMART POWER. BUILT FOR AUSTRALIA.
By storing excess solar power, the system reduces reliance on the grid and lowers electricity bills. Maximise the use of your solar panels and improve long-term energy efficiency.
Eligible households may qualify for available battery rebate programs or incentives, depending on state regulations and system eligibility.
Scalable battery capacity designed to support daily energy needs and future demand.
With built-in backup capabilities, the system maintains a stable energy supply during outages. Essential loads remain powered when grid interruptions occur.
Store unused daytime solar energy and deploy it when generation drops. Gain greater control over when and how your energy is used.
The ESY Sunhome incorporates advanced BMS (battery management system) protection, ensuring safety through continuous monitoring against overcharging, overheating, and short circuits and system is approved by the Clean Energy Council (CEC) for use in Australia, meeting local compliance and safety requirements.
