Hoymiles Launches the HiBattery 4020 Series of Intelligent Home Energy Storage

In a significant move to enhance the efficiency and safety of solar power systems, Hoymiles has officially introduced its third generation of home energy storage solutions, the HiBattery 4020 series. Announced on June 2, 2026, this new lineup is set to revolutionize how homeowners utilize solar energy while ensuring greater reliability.

The HiBattery 4020 series comprises two innovative models: the HiBattery 4020 X, a hybrid model designed for direct connection to photovoltaic (PV) modules, and the HiBattery 4020 AC, an AC-coupled system that can be integrated with existing solar setups to add a storage functionality. Each model features an enhanced battery capacity which can be further expanded, allowing homeowners to tackle rising energy costs.

Key Features of the HiBattery 4020 Series

1. Increased Capacity and Scalability: The HiBattery 4020 series boasts a base battery capacity of 4 kWh, with the flexibility to expand up to 16 kWh through modular battery stacks. This scalability means homeowners can tailor their energy storage capabilities to match their specific needs.
2. Efficient Energy Conversion: Equipped with a built-in 2500 W inverter, the system achieves a maximum DC/AC conversion efficiency of 96.5%, ensuring that energy utilization is maximized, which translates to lower electricity bills.
3. Optimized Solar Harvesting: The HiBattery 4020 X includes four Maximum Power Point Tracking (MPPT) inputs with the capacity to handle up to 4 kW of PV input power, which enhances the effectiveness of solar energy collection, even on cloudy days.
4. Energy Management System (EMS): A standout feature of the HiBattery 4020 series is its AI-driven EMS, which differentiates itself from traditional systems. By recalibrating energy strategies every three hours based on real-time variables like energy prices and weather forecasts, it can intelligently manage energy expenditure.
5. Safety and Reliability: Safety is a cornerstone of the HiBattery 4020 series, incorporating automotive-grade LiFePO4 battery cells coupled with advanced 48-step protection mechanisms. The system also features an aerosol fire suppression system, pressure relief mechanisms, and intelligent self-heating technology that adapts to charge levels and solar energy surplus.

Meeting Energy Needs Even During Outages

The design of the HiBattery 4020 series not only emphasizes energy independence but also addresses the need for reliable power during blackouts. By maximizing solar energy usage, homeowners can ensure that critical appliances like refrigerators, lighting, and medical devices remain powered during outages. For those in remote areas without grid access, the series supports off-grid living.

Dr. Yang Bo, CEO of Hoymiles, highlighted the commitment to safety in energy storage, stating, "Energy storage for households must fundamentally be safe before it can truly become accessible." The HiBattery 4020 series reflects this commitment by providing secure storage solutions for everyday use and unexpected emergencies.

The HiBattery 4020 series will be available across Europe starting June 2026, marking a new era in home energy management and sustainability. For more information about the series, please visit Hoymiles HiBattery 4020 and Hoymiles HiBattery 4020 AC.
