As more homeowners embrace solar energy, the need for smarter, more reliable energy storage has never been greater. Introducing the Hoymiles HiOne—an all-in-one Battery Energy Storage System (BESS) that combines a hybrid inverter, battery, Energy Management System (EMS), and gateway into one compact, intelligent solution. Designed to maximise your solar investment, HiOne helps you reduce electricity bills, improve energy independence, and keep your home powered when it matters most.
One System. Complete Home Energy Management.
Unlike conventional battery systems that require multiple standalone components, HiOne integrates everything into a single platform. The system combines a hybrid inverter, modular battery, optional V2X EV charging, smart monitoring via the S-Miles Cloud platform, and a gateway capable of powering your entire home during grid outages.
0 ms Backup Switching
Power outages no longer mean interruptions to your daily life.
With 0 ms backup switching, Hoymiles HiOne provides true UPS-grade backup power, allowing essential and inductive appliances such as air conditioners, refrigerators, washing machines, and home office equipment to continue operating seamlessly during a blackout.
Higher Solar Generation, Greater Savings
Hoymiles HiOne is engineered to help homeowners capture more solar energy throughout the day.
Key performance features include:
- Up to 98.5% maximum efficiency
- 4 MPPTs supporting multiple roof orientations
- 20 A input current per MPPT
- 170 V start-up voltage for earlier energy generation each morning
Together, these features maximise solar production, improve system flexibility, and help homeowners achieve greater long-term electricity savings.
Scalable Battery Storage That Grows with You
Every home has different energy needs—and those needs can change over time.
Hoymiles HiOne features modular 8 kWh LiFePO₄ battery packs that can be expanded up to 64 kWh by connecting up to 8 battery packs per inverter. Whether you’re installing solar for your home today or planning for future energy demands, HiOne offers the flexibility to grow alongside you.
HiOne is designed to grow with your energy needs. Its intelligent Battery Management System automatically balances the State of Charge (SOC) whenever a battery module is added or replaced. With an independent bidirectional DC/DC module in every battery, the system reduces pre-charging time, simplifies maintenance, and lowers the cost of future upgrades.
Built for Long-Term Reliability
Hoymiles HiOne is engineered to perform in demanding environments.
Powered by premium 314 Ah LiFePO₄ battery cells, the system delivers:
- Over 8,000 charging cycles
- IP66 waterproof and dustproof protection
- Self-heating technology for reliable operation from -30°C to 65°C
Combined with robust battery protection, HiOne is built to deliver dependable performance for years to come.
Faster Installation, Cleaner Design
Installation is quicker and easier thanks to Hoymiles HiOne’s plug-and-play architecture.
Features such as:
- Spring terminal connections
- Cable-free stackable battery modules
- Pluggable data transfer stick
- Plug-in smart meter
help reduce installation time while minimising on-site labour. The compact all-in-one design also occupies less space than traditional battery systems, while concealed wiring behind the side grille creates a clean, modern appearance that blends seamlessly into contemporary homes.
