Introducing Hoymiles HiOne: All-in-One Battery Storage, Now Available from Solen

The new Hoymiles HiOne All-in-One Battery Energy Storage System (BESS) is now available from Solen across the UK and Ireland.

Backed by Hoymiles' established experience in global solar and microinverter technology, HiOne brings inverter technology, modular battery storage and intelligent energy management together in one scalable system.

With single-phase and three-phase options available, it's a flexible solution for residential and commercial installations that can expand as customers' energy requirements change.

Who Are Hoymiles?

While Hoymiles may be a new name to some Solen customers, the company has an established global presence in solar technology and has built a strong reputation through its microinverter solutions.

That experience now extends into energy storage with HiOne, bringing Hoymiles' expertise in power electronics, intelligent energy management and solar technology together in an all-in-one battery storage platform.

For installers considering a new battery and inverter platform, the manufacturer behind the technology matters. Hoymiles brings an established track record in the global solar industry, helping give installers greater confidence when specifying HiOne for their customers.

Internationally Recognised Design and Usability

HiOne has already gained international recognition for its design and usability.

The system has received a Platinum award at the London Design Awards 2026, a Gold award at the French Design Awards 2026, and recognition through the Red Dot Design Concept Award.

HiOne has also achieved TÜV Rheinland usability certification, recognising areas including installability and repairability – important considerations for installers working with the system in the field.

Together, these accolades provide further independent recognition of the thinking behind HiOne's design, installation and user experience.

Everything Energy. One Smart System.

One of the big advantages of HiOne is its integrated design.

The inverter, battery and intelligent Energy Management System (EMS) work together as one system, reducing the number of separate components required.

Concealed wiring and a compact design also help create a clean, seamless finish once installed.

For installers, that means a simpler system to specify and a professional-looking installation for the customer.

Designed to Make Installation Simpler

Time on site matters.

HiOne uses a plug-and-play, wire-free stacking design to simplify installation, with commissioning completed through the S-Miles Cloud/App.

Hoymiles states that installation can be completed in as little as 15 minutes, covering battery stacking, cable connection and intelligent commissioning.*

Start at 8kWh. Scale up to 64kWh.

Not every customer needs the same amount of battery storage – and what they need today might change in the future.

HiOne's modular design allows storage capacity to be expanded from 8kWh up to 64kWh, with up to eight battery packs supported per inverter.

Built-in bidirectional DC/DC technology also allows new and existing battery packs to be used together, with automatic State of Charge (SOC) balancing.

This means installers can specify the capacity needed today, with the option to add more storage if the customer's requirements change.

Greater Flexibility When Designing a System

HiOne offers up to four independent MPPTs, giving installers more flexibility when working with different roof orientations and more complex PV layouts.

Other key features include:

• Single-phase and three-phase configurations
• Up to 200% DC/AC oversizing
• Intelligent Energy Management System
• Integrated AFCI protection
• IP66-rated enclosure
• Modular battery expansion
• Whole-home backup capability with the Hoymiles Gateway
• S-Miles Cloud monitoring

Built for Long-Term Performance

At the heart of the system are 314Ah LiFePO₄ battery cells, designed to deliver more than 8,000 life cycles.

HiOne also features an IP66-rated enclosure for indoor and outdoor installations, while self-heating battery technology helps maintain performance in low-temperature environments.

Whole-Home Backup

For customers looking for greater energy resilience, HiOne can be paired with the Hoymiles Gateway to provide whole-home backup functionality.

The system supports 0ms backup switching, helping keep connected loads powered in the event of a grid outage.

What Does Our Sales Team Think?

"Installers are looking for battery storage systems that are straightforward to specify, easy to scale and built to perform. HiOne delivers exactly that, making it a valuable addition to the Solen portfolio."
