The BLUETTI B500 is an expansion battery for fixed BLUETTI energy storage systems. With 4.96 kWh of gross storage capacity per battery module, the B500 forms the building block that allows a BLUETTI EP600 or EP760 system to be matched to the actual energy demand of a home or small commercial location.
While compact power stations are mainly intended for mobile use, the B500 is designed for serious energy storage in a home, garage, technical room, outbuilding or business environment. The battery works together with a compatible inverter, a Battery Management System and the BLUETTI App. This creates a scalable system for solar energy storage, backup power, self-consumption and smart charging and discharging.
• 4,960 Wh of additional storage capacity per B500 battery module
• LiFePO4 battery chemistry for safety, stability and long service life
• Suitable for modular BLUETTI EP600 and EP760 home battery systems
• IP65 housing for indoor and sheltered outdoor installations
• Advanced BMS with monitoring of voltage, current and temperature
• App monitoring via the connected BLUETTI energy system
• Ideal for solar self-consumption and backup power scenarios
• Expandable system concept for homes and light commercial applications
The B500 is a battery module and not a standalone power station. The battery therefore has no built-in 230V outputs for direct use. For backup power, solar input, grid connection and smart energy management, a compatible BLUETTI inverter is required, such as the EP600 or EP760, together with correct installation according to applicable electrical regulations.
The demand for home batteries is increasing as more households have solar panels, energy tariffs vary and the self-consumption of generated power becomes more important. A battery such as the BLUETTI B500 makes it possible to temporarily store energy within a larger BLUETTI ESS system. During the day, generated solar energy can be stored and later used when the sun is not shining or when household consumption is higher.
Within the BLUETTI ecosystem, the B500 is particularly interesting because the capacity per module is large enough to make a noticeable difference. One module adds 4.96 kWh. Multiple modules can together form a system that suits small, medium or larger energy requirements. This makes the system suitable for users who want to start small but expand later.
The B500 uses LiFePO4 technology. This battery chemistry is known for thermal stability, safety and long service life. In combination with a Battery Management System, the battery is continuously monitored for relevant parameters such as voltage, current and temperature. This is important for a fixed home battery because the system must not only deliver sufficient capacity, but above all continue to operate reliably and safely.
The B500 stores DC energy in the battery cells. The connected BLUETTI inverter then manages how this energy is charged, converted and used. Depending on the system configuration, the energy can come from solar panels, the electricity grid or a combination of both.
In a compatible EP600 system, one EP600 can be combined with multiple B500 battery modules. For larger configurations, multiple inverters and battery modules can be used. With the EP760, the B500 is used as the battery base for a powerful single-phase home battery system. The exact capacity, backup function and power output always depend on the selected inverter, the number of B500 modules and the installation.
The system can be monitored via the BLUETTI App. This includes battery status, energy flows, operating mode, error messages and system settings. The B500 is therefore not just a passive battery, but part of an intelligent energy storage system.
Use the B500 as a storage module within a BLUETTI home battery system to make use of generated solar energy later in the day.
In combination with a suitable BLUETTI inverter and correct backup installation, the B500 can contribute to a larger energy reserve during power outages.
By storing solar energy instead of feeding it directly back to the grid, a household can use more of its own generated electricity.
Small businesses, workshops and technical rooms can also benefit from modular storage capacity and backup options.
The BLUETTI B500 is suitable for users looking for a fixed, expandable battery solution who need more than a compact power station. The module is especially suited to situations where reliability, scalability and integration with a complete inverter solution are important.
• Households with solar panels that want to use more of their own electricity
• Homes where a reliable backup solution is desired
• Users who want to expand an EP600 or EP760 system
• Customers who prefer modular growth instead of buying an oversized system immediately
• Small commercial locations requiring energy storage and reserve capacity
• Installations where a fixed, robust battery setup is more logical than a mobile power station

When the B500 is part of a well-designed BLUETTI system, solar energy can be stored for moments when the home needs power.
By using more of your own electricity, energy storage becomes more attractive in a market where feed-in, net metering and variable tariffs are becoming increasingly important.
With the modular concept, storage capacity can be better matched to actual consumption without immediately choosing an unnecessarily large system.
The BLUETTI B500 is intended for fixed installation by qualified installers or technically competent persons. The battery module is heavy and is installed as part of a stacked setup. A firm, level surface, correct mounting and proper electrical connection are essential.
