Hoymiles Unveils the HiBattery 4020 Series for Advanced Home Energy Storage

In a significant step towards enhancing energy independence for homeowners, Hoymiles has officially launched its HiBattery 4020 Series, the third generation of their plug-in home battery systems. This new product line features advanced technology designed to make energy storage safer and more intelligent.

The HiBattery 4020 Series includes two innovative models: the HiBattery 4020 X and the HiBattery 4020 AC. The former is a hybrid model that connects directly to solar panels, while the latter integrates with existing AC systems, enabling homes to benefit from efficient energy storage solutions. Both models boast an increased battery capacity and advanced protective mechanisms, alongside an in-house developed AI algorithm.

Enhanced Energy Capacity

The series introduces batteries with a standard capacity of 4 kWh, which can be expanded by adding additional battery modules, enabling a total capacity of up to 16 kWh. This modular design allows homeowners to customize their energy storage according to their specific needs. Furthermore, the HiBattery systems come equipped with a built-in inverter boasting a power output of 2500 W, ensuring an impressive energy conversion efficiency, reaching up to 96.5% DC/AC.

The HiBattery 4020 X model stands out with its four MPPT inputs, capable of handling photovoltaic inputs of up to 4 kW. This is intended to optimize solar energy collection and usage, ultimately reducing reliance on grid power. This not only maximizes energy self-consumption during daily activities but also provides continuous power for essential appliances — including refrigerators, lighting, and medical devices — during outages. Moreover, the energy storage system is designed to function seamlessly in off-grid locations, such as remote homes or self-sufficient living environments.

AI-Driven Energy Management

One of the standout features of the HiBattery 4020 Series is its AI-based Energy Management System (AI-EMS). Unlike traditional energy management systems that rely on fixed schedules, Hoymiles' AI-EMS recalibrates its energy strategies every three hours based on electricity prices, weather forecasts, and household consumption patterns.

This dynamic management system includes key functionalities like the AI-TOU optimization cycle, which constantly adjusts charging and discharging strategies to minimize electricity costs. Additionally, users can monitor real-time energy consumption, savings, and system performance through a simple visual interface, making it easier to manage their energy usage effectively.

Focus on Safety and Reliability

Safety is at the forefront of the HiBattery 4020 Series design. Hoymiles employs automotive-grade LiFePO4 battery cells, integrated with a 48-layer Battery Management System (BMS) that features intelligent cell balancing and multiple hardware safety elements. Key safety features include:

• - An integrated aerosol fire suppression system
• - Pressure relief and overheat protection for PV inputs
• - Smart self-heating functions that adjust to charging conditions and excess sunlight exposure, ensuring stable operation in extreme temperatures ranging from -20°C to 55°C
• - Dust and water resistance, certified at IP66
• - DC/DC balancing at the battery level, ensuring smooth compatibility between new and existing battery modules for easy scalability.

With these robust safety features, Hoymiles aims to provide users with peace of mind for all situations, from daily use to unexpected emergencies.

Hoymiles' HiBattery 4020 Series is set to hit the European market in June 2026, offering consumers an effective way to harness solar energy safely and intelligently.
