The Hoymiles HiBattery 4020X is an all-in-one solar and battery storage system designed to make home energy storage simple. Combining a 4.02kWh LFP battery, solar input and intelligent energy management in one compact unit, it allows you to store excess solar energy and use it later when your home needs it.

Ideal for homes looking for a straightforward way to add battery storage, the HiBattery 4020X can work with solar panels or be used to intelligently charge from the grid during cheaper tariff periods.

Make More of Your Solar

Instead of exporting unused solar generation back to the grid, the HiBattery 4020X can store surplus energy for use later in the day.

That means solar generated during daylight hours can help power your home in the evening and overnight, increasing your solar self-consumption and reducing the amount of electricity you need to purchase from the grid.

Already have solar? The HiBattery 4020X can also provide a straightforward route to adding battery storage to an existing system.

Smart Energy Management

Hoymiles' intelligent energy management system can optimise when energy is generated, stored and used. This makes the system particularly useful alongside time-of-use electricity tariffs, where energy can be stored when electricity is cheaper and used when grid prices are higher.

The system can be monitored and managed through the Hoymiles ecosystem, giving homeowners greater visibility and control over their energy use.

Built with Safety in Mind

The HiBattery 4020X uses LFP battery cells alongside an intelligent battery management system with multiple layers of protection.

Safety features include:

• PV input over-temperature protection

• Internal fire-extinguishing system

• Pressure relief valve

• Stack connector temperature monitoring

• Intelligent cell balancing

• Low-temperature battery heating

• Independent overcharge and over-discharge protection

Start with 4kWh. Expand Later.

One of the biggest advantages of the HiBattery platform is its modular design.

Start with the 4.02kWh HiBattery 4020X and add additional battery capacity as your energy requirements grow, taking the system up to 16.08kWh.

Each battery incorporates its own bidirectional DC/DC module, allowing the system to automatically manage differences in battery state of charge when additional capacity is installed.
