Lunergy Plug-in Home Batteries

For many households, installing solar panels is the first step towards more sustainable energy use. With the Lunergy energy system, this installation can be expanded with energy storage, so the electricity generated by your panels does not have to be exported to the grid immediately.

The Lunergy Hub 2400 AC operates as a fully AC-coupled system and connects to an existing solar PV installation. Combined with the BP5200 battery modules, it forms a scalable home battery that stores surplus solar energy and makes it available later for use in the home.

Scalable storage up to 78.3 kWh

AC-coupled for existing solar panels

Plug-in installation via a standard socket

Smart energy management via smart meter data

Home Battery for your Solar Panels

The Lunergy energy system allows you to expand an existing solar installation with energy storage. Instead of exporting surplus solar electricity directly to the grid, the energy is stored and used later when household demand increases. This allows a larger share of the energy you generate to be used within your own home.

The system works alongside your existing solar panels and inverter, allowing energy storage to be added without major modifications to the installation. Using real-time data from the smart meter, the Lunergy Hub automatically adjusts charging and discharging based on current household consumption and available solar energy. When there is a surplus, the battery charges automatically. When energy demand increases, the stored electricity becomes available again. This creates a better balance between generation, storage and consumption.

Smart Energy Storage with the Lunergy Hub

The Lunergy Hub 2400 AC forms the heart of the system and works together with the modular BP5200 battery modules. Connected via a standard wall socket, the hub can deliver up to 800 W of output power. Stored energy can therefore be used directly within the home instead of being exported to the electricity grid.

For households that require more power, the hub can also be connected to a dedicated circuit in the consumer unit. In this configuration, the hub delivers up to 2.4 kW of continuous output, with peak loads up to 4.8 kW. The storage capacity can easily grow with the system by combining up to three BP5200 batteries per tower. By combining multiple towers and connecting them to separate phases, the total energy storage can increase to a maximum of 78.3 kWh. This creates a flexible energy system that grows together with your household’s energy needs.
