Sodium-ion residential battery storage is moving into the home energy market with a new product from German startup Revolta. The company has introduced a high-voltage system for residential use. It uses modular Sodium-ion Battery packs and supports flexible sizing. As a result, homeowners can match storage capacity to daily energy needs while keeping the system compact.
Sodium-Ion Residential Battery Storage for Homes
Revolta designed the new system around 2.0 kWh battery modules. Users can connect up to 10 modules in parallel. Therefore, total system capacity can scale from a small setup to a maximum of 20 kWh. This modular approach gives installers more freedom. It also helps homeowners choose a system that fits current consumption and future growth.
Each battery module measures 284 mm × 186 mm × 260 mm. In addition, each unit weighs 19 kg. The compact size supports easier placement in residential settings. Revolta also built the system for high-voltage operation. According to the company, the nominal voltage reaches 450 V DC. That design supports direct connection to the inverter through a dedicated control unit.
Sodium-Ion Residential Battery Storage Specifications
Revolta lists an energy density of 105 Wh/kg for the battery system. The company also states that charging and discharging power ranges from 0.6 kW to 1.2 kW. However, actual output depends on the state of charge. Even so, the system delivers efficiency above 95%, which is a strong figure for residential storage. Moreover, low standby losses help preserve stored energy over time.
The battery carries an IP65 protection rating. As a result, it offers solid resistance against dust and water ingress. Revolta also says the system holds several certifications, which supports broader installer confidence. Noise emissions stay below 40 dB, according to the datasheet. Therefore, the unit suits residential environments where quiet operation matters.
Another notable feature is standby endurance. Revolta says the battery can remain in standby for more than one year without needing a recharge. That long standby capability adds flexibility for homeowners, installers, and project developers. It also supports smoother logistics before final commissioning.
Sodium-Ion Residential Battery Storage Installation
Revolta aims to simplify installation and setup. The company uses a control unit to connect the battery system with the inverter. At the same time, the control unit acts as the interface for system management. Revolta says users can complete commissioning through a plug-and-play over-the-air process. They can use the company’s smartphone app or a Bluetooth connection to finish setup.
This installation approach can reduce complexity during deployment. In turn, installers can complete projects more efficiently. Revolta also plans to expand the list of compatible inverter models. The company will add new models as manufacturers issue the required approvals. That strategy should widen integration options over time.
Sodium-Ion Residential Battery Storage Market Launch
Revolta presented the new battery system at The smarter E trade fair in Munich. The company plans an official market launch in September 2026. In addition, several pilot projects are already in preparation. These early deployments should help demonstrate system performance in real residential settings.
The company reports steady interest from end customers. It usually directs those inquiries to suitable local installers. Meanwhile, Revolta is building its sales structure around a three-tier distribution model. The company wants to work through wholesalers and installers. It has already started discussions with distributors. Furthermore, Revolta expects to complete its sales network by 2027.
Sodium-Ion Residential Battery Storage Expansion Plans
Revolta will focus first on the German market. After that, the company plans to expand into other European countries. According to the company, the high-voltage system connects directly to the inverter rather than the grid. Therefore, this design can support entry into additional markets with fewer technical barriers.
Overall, Revolta’s new product brings a clear value proposition to the residential storage segment. It combines sodium-ion chemistry, high-voltage architecture, modular capacity, and compact dimensions in one system. The battery offers 2.0 kWh per module, up to 20 kWh total capacity, 450 V DC nominal voltage, more than 95% efficiency, and sub-40 dB noise levels. With IP65 protection, long standby capability, and app-based commissioning, the system gives homeowners and installers a practical new option for home energy storage in 2026.
