Unlocking Home Energy Autonomy: How Hoymiles HiOne Redefines Efficiency and Reliability

Tackling Complex Rooftops: 4 MPPTs to Capture the Value of Every Ray of Sunshine

Facing the diverse rooftop orientations and partial shading common in European homes, HiOne features up to 4 independent MPPT channels, fundamentally eliminating the bottleneck effect in PV strings. This is like assigning a dedicated "efficiency optimizer" to each group of solar panels with different orientations or shading impact.

Each MPPT channel independently tracks and locks onto the optimal operating voltage and current for that channel, ensuring that even if some modules underperform due to orientation or shading, the others continue to operate at peak efficiency—significantly boosting overall system energy yield and optimizing power generation revenue.

Each MPPT channel supports an input current of up to 20 A, far exceeding the 16 A of comparable products. This not only ensures full compatibility with today's mainstream high-power PV modules but also reserves ample upgrade headroom for future even higher-power modules. It also opens up applications such as small C&I systems and PV carports.

Protecting Home Power with Uninterrupted Power Supply

Grid stability is the cornerstone of the home energy experience. HiOne understands European users' high demands for power supply continuity, achieving millisecond breakthroughs in on-grid to off-grid transfer technology.

When an unexpected grid outage occurs, the system completes a smooth transfer from on-grid to off-grid mode in 0 milliseconds. For critical loads such as refrigerators, lighting, routers, and medical devices, this process is completely imperceptible—power supply remains uninterrupted, truly enabling "life goes on, even when the grid goes down." This design not only solves the challenge of power supply during blackouts but also gives users full control over their home energy system.

Modular Battery Architecture for Future-proof scalability and Long-Term Reliability

Home energy needs are dynamic, and energy storage systems must be able to "grow." HiOne adopts an innovative modular battery architecture, setting a new benchmark for flexibility in scaling-up, operational stability, and maintenance convenience.

• Intelligent Modular Architecture: Each battery module features an independent bidirectional DC/DC controller, ensuring individual performance differences never compromise the overall system energy yield.

• "Mix & Match" Flexibility: This unique architecture allows you to seamlessly mix new and old modules—or batteries with different states of health—delivering consistent power and maximum reliability throughout the system's lifecycle.

• Scalable Investment: Avoid large upfront costs by starting small. Support for single-module increments allows you to expand from 8 kWh to 64 kWh (up to 8 modules in parallel), providing a tailored fit for any home, from standard residences to large villas.

• Simplified Maintenance: If a single module fails, it can be replaced individually without resetting or impacting the rest of the storage system, significantly reducing long-term O&M costs.

The launch of the HiOne All-in-One BESS marks a new stage of intelligent integration for home energy systems. It deeply adapts to Europe's diverse residential environments, precisely responds to each household's unique energy needs, and possesses the long-term evolution capability for the future, making green, efficient, and intelligent energy living truly accessible.
