HANGZHOU, China, June 1, 2026 /PRNewswire/ -- Hoymiles announced the official launch of its new HiBattery 4020 Series, the third-generation of its plug-in home battery system. The series features Hoymiles first hybrid model HiBattery 4020 X which is directly connected to PV modules, and the AC-coupled model HiBattery 4020 AC which is paired with existing home solar system to add the storage function. Equipped with higher battery capacity and adopting advanced protection mechanisms and self-developed AI algorithm, both models are designed to make residential energy storage safer, smarter, and help homeowners save more on energy costs.
 
Hoymiles Officially Launched HiBattery 4020 Series of Plug-In Home Energy Storage
High Performance and Energy Independence for Everyday Life and Emergencies
Compared with previous plug-in batteries, the HiBattery 4020 Series delivers greater battery capacity and scalability to boost home energy storage:
- Both models feature a 4 kWh battery capacity, expandable up to 16 kWh with extra modular battery stacks
- They come with a built-in 2500 W inverter for efficient power conversion, with a maximum DC/AC efficiency of 96.5% for high energy utilization
- The HiBattery 4020 X is built with 4 MPPT inputs, with up to 4 kW PV input for optimized solar harvesting
Besides reducing reliance on the grid by maximizing self-consumption of solar energy in daily use, the HiBattery 4020 system also ensures continuous power supply for essential appliances such as refrigerators, lighting, and medical equipment during grid outages. It can also sustain power in off-grid settings like remote homes and self-sufficient living environments without grid access.
AI-EMS for Smarter Energy Use and Lower Electricity Bills
One of the core technologies in the HiBattery 4020 Series is Hoymiles' AI Energy Management System (AI-EMS), which is built on its self-developed AI model trained with over 30 million parameters.
Unlike traditional systems that rely on fixed daily schedules, HiBattery 4020 dynamically recalculates energy strategies every three hours based on electricity prices, weather forecasts, and household consumption patterns.
Key capabilities include:
- AI-TOU optimization: A 3-hour rolling cycle that continuously adjusts charging and discharging strategies to capture the lowest electricity costs
- Energy Ledger: A simple visual dashboard that tracks energy usage, savings, and system performance in real time
Safety and Reliability for Real-World Living
Safety is the foundation of the HiBattery 4020 Series. Built with automotive-grade LiFePO4 battery cells, the system integrates 48-layer BMS protection, intelligent cell balancing, and multiple hardware-level safeguards:
- Built-in aerosol fire suppression system
- Pressure relief and PV Input Overheat Protection
- Intelligent self-heating that responds to charging conditions and solar surplus — for stable operation from -20℃ to 55℃
- IP66-rated dust and water resistance
- Pack-level DC/DC balancing that enables seamless compatibility between new and existing battery modules, ensuring hassle-free scalability
These features guarantee a real-life durability for both indoors and outdoors environments, as well as in everyday accidents.
"Home energy storage must be fundamentally safe before it can be truly accessible," noted Hoymiles CEO Dr. Yang Bo. "HiBattery is designed to provide peace of mind in every scenario—from daily use to unexpected emergencies."
The HiBattery 4020 Series will be available for purchase across Europe starting from June 2026.

Hoymiles Introduces HiBattery 4020 Series of Plug-In Home Energy Storage to Bring Solar Safety and Intelligence to the Next Level
TOKYO, May 30, 2026 /PRNewswire/ -- Smartee Denti-Technology, a global provider of clear aligner solutions, recently held a two-day Certified Seminar on Mandibular Advancement Repositioning Technology in Tokyo on May 23–24, 2026. The program focused on evidence-informed clinical management of jaw discrepancy cases with clear aligner therapy.
Together with local Japanese clinicians, Smartee lecturers Dr. Tao Guo and Dr. Xiaotian Liu shared their insights into the clinical application of Smartee's GS mandibular advancement repositioning technology and discussed its role in addressing complex orthodontic cases within clear aligner therapy.
Growing Interest in Advanced Clear Aligner Solutions in Japan
In recent years, Smartee has continued to expand academic exchanges with orthodontic professionals in Japan. Through this interactions, the company has observed increasing public awareness of oral health and dental aesthetics, alongside growing interest in orthodontic treatment among adult patients.
At the same time, the broader adoption of digital dentistry has contributed to a favorable environment for the development of advanced aligner-based treatment approaches.
During academic exchanges with local clinicians, Smartee observed continued clinical interest in the management of Class II skeletal malocclusions. Such cases often require considerations beyond routine dental alignment and may require a comprehensive understanding of mandibular positioning and occlusal relationships.
Two-Day Clinical Training Program
The seminar agenda was designed to provide participants with both theoretical understanding and practical exposure to Smartee mandibular advancement repositioning technology.
On Day 1 (May 23), sessions focused on the introduction, classification of malocclussion, indications, mechanism of action, and clinical workflow of the technology. Participants discussed diagnostic considerations and treatment planning approaches related to mandibular advancement protocols.
Day 2 (May 24) covered more advanced clinical topics, including radiographic observations related to temporomandibular joint remodeling adaptation following mandibular advancement, retreatment strategies for challenging cases, and early intervention approaches for growing patients.
The seminar concluded with a hands-on bite registration workshop, where participants practiced occlusal registration techniques, followed by a certification ceremony.
Active Clinical Exchange with Japanese Orthodontists
Throughout the seminar, participants engaged in active clinical discussions with the speakers, raising questions related to diagnosis, treatment indications and patients management.
Clinicians newly introduced to the technology discussed the diagnostic classification system for malocclusions and examined differences in mandibular morphology across patient types.
Participants also exchanged views on patient compliance in mandibular repositioning protocols, including practical communication strategies for improving adherence during treatment.
"The level of clinical interaction throughout the seminar was highly encouraging," said Dr. Tao Guo. "Participants connected the discussions closely with cases encountered in daily practice and raised practical questions regarding case selection, treatment indications, and patient compliance strategies. We appreciated the opportunity to exchange clinical perspective with orthodontic professionals in Tokyo."
Smartee stated that it will continue strengthening academic exchange and professional training initiatives in Japan as part of its long-term commitment to supporting local orthodontic professionals and expanding localized services in the Japanese market.
