Sodium-ion home battery systems are gaining traction in residential energy storage. German startup Revolta has now introduced a high-voltage solution for households. The new system uses modular Sodium-ion Battery packs. As a result, homeowners can scale storage capacity to match daily electricity needs. Revolta plans to officially launch the product in September 2026 after presenting it at The smarter E trade fair in Munich.
Sodium-ion home battery offers modular storage
Revolta designed the system around 2.0 kWh battery modules. Homeowners can connect up to 10 modules in parallel. Therefore, the total storage capacity can reach 20 kWh. This modular setup gives installers and customers flexibility. They can size the system for smaller homes or larger residential energy demands.
Each module measures 284 mm × 186 mm × 260 mm. In addition, each unit weighs 19 kg. The compact form factor supports easier handling during installation. Revolta also says users can adapt the module configuration freely. That approach helps tailor the battery system to individual household requirements.
Sodium-ion home battery delivers high-voltage performance
Revolta built the product as a high-voltage residential storage system. According to the company datasheet, the battery has a nominal voltage of 450 V DC. Moreover, the system reaches an energy density of 105 Wh/kg. These figures position the product as a practical option for modern home energy setups.
Charge and discharge power range from 0.6 kW to 1.2 kW. However, the exact output depends on the state of charge. Even so, the battery maintains strong operational performance for residential use. Revolta also reports system efficiency above 95%. Consequently, homeowners can expect efficient energy storage and delivery.
Sodium-ion home battery supports simple installation
Revolta focused strongly on installation simplicity. The company uses a control unit to connect the battery and the inverter. This unit acts as the interface between both components. As a result, the system integrates into residential energy systems in a straightforward way.
The company says commissioning follows a plug-and-play over-the-air process. Installers can complete setup through Revolta’s smartphone app or by using a Bluetooth connection. Therefore, the startup aims to make deployment faster and more convenient for installation partners.
Revolta is also expanding inverter compatibility. The company said it will add more approved inverter models as manufacturers grant the necessary approvals. This strategy should widen the product’s appeal across different residential solar and storage configurations.
Sodium-ion home battery includes strong efficiency and protection
The system combines efficiency with practical residential features. Revolta states that the battery achieves more than 95% efficiency. In addition, the unit carries an IP65 protection rating. That rating supports reliable operation in demanding residential environments.
The company also lists several certifications for the product. Furthermore, noise emissions stay below 40 dB. This low noise level makes the system suitable for home settings where quiet operation matters. Revolta also describes standby losses as very low. Notably, the battery can remain in standby for more than one year without needing a recharge.
Sodium-ion home battery launch starts in Germany
Revolta first unveiled the residential storage system at The smarter E in Munich. The company plans the official market launch for September 2026. At the same time, it is already preparing several pilot projects. These projects should help demonstrate the product in real residential applications.
Initially, Revolta will focus on the German market. After that, the company aims to expand into other European countries. The spokesperson explained that the high-voltage storage system connects directly to the inverter instead of the grid. Therefore, the company sees a smooth path toward broader European rollout.
Revolta is also building its sales network through a traditional three-tier model. The company intends to work through wholesalers and installers. In addition, it has started talks with distributors. Revolta expects to have its sales network fully established by 2027.
Why Revolta’s sodium-ion home battery stands out
Revolta’s new product brings together modular design, high-voltage architecture, and efficient operation. Homeowners can start with 2.0 kWh and scale up to 20 kWh. They also get a compact module size, 450 V DC nominal voltage, more than 95% efficiency, and quiet performance below 40 dB.
Just as importantly, the system supports simple setup through app-based and Bluetooth commissioning. With an IP65 rating and very low standby losses, the battery suits modern residential energy storage needs. As the September 2026 launch approaches, Revolta’s sodium-ion home battery adds a notable new option to Germany’s home storage market.
