Sodium-ion home battery technology is moving into the residential storage market in 2026. German startup Revolta has introduced a high-voltage battery system for homes. The new product uses modular Sodium-ion Battery packs. As a result, homeowners can scale storage capacity to match daily energy needs.
Revolta designed the system for residential use. Each battery module stores 2.0 kWh. Moreover, users can connect up to 10 modules in parallel. This setup allows the system to reach a total capacity of 20 kWh. Therefore, the product can serve smaller homes as well as households with higher storage demand.
Sodium-ion home battery specs for residential use
Revolta gave the sodium-ion home battery a compact format. Each module measures 284 mm × 186 mm × 260 mm. In addition, each unit weighs 19 kg. This combination supports easier handling during transport and installation.
The company says the module layout stays flexible. Installers can adapt the configuration to suit each project. Consequently, the system can fit a wide range of residential energy storage setups. That flexibility may appeal to homeowners who want a storage system that grows over time.
According to the company datasheet, the system delivers an energy density of 105 Wh/kg. It also operates at a nominal voltage of 450 V DC. Meanwhile, charge and discharge power ranges from 0.6 kW to 1.2 kW, depending on the state of charge. Revolta also reports system efficiency above 95%. These figures position the product as a practical option for daily home energy management.
Sodium-ion home battery design and performance
Revolta built the sodium-ion home battery for indoor and outdoor residential environments. The system carries an IP65 protection rating. Therefore, it offers strong protection against dust and water ingress. The company also states that the battery holds several certifications, which supports residential deployment.
Noise levels remain low as well. Revolta specifies noise emissions below 40 dB. As a result, the battery should suit homes where quiet operation matters. The company also describes standby losses as very low. In addition, Revolta says the battery can remain in standby for more than one year without needing a recharge. That feature may help in projects where the battery sits unused for extended periods before active operation.
Sodium-ion home battery installation and commissioning
Revolta emphasizes simplified installation. The company uses a control unit to link the battery and the inverter. This control unit acts as the interface between both components. At the same time, Revolta continues to expand its list of compatible inverter models as manufacturers approve integration.
The company also highlights a plug-and-play over-the-air commissioning process. Installers can complete setup through Revolta’s smartphone app or through a Bluetooth connection. Therefore, the installation process should move faster and stay more straightforward for residential projects. Easy digital setup can also help reduce commissioning time on site.
Sodium-ion home battery market launch in 2026
Revolta presented the sodium-ion home battery at The smarter E trade fair in Munich in 2026. The company plans an official market launch in September 2026. At the same time, several pilot projects are already in preparation. These early deployments should help introduce the product to installers and homeowners in real-world settings.
For sales, Revolta is focusing on a traditional three-tier model. The company aims to move products through wholesalers and then to installers. In addition, it is already holding initial talks with distributors. Revolta says it receives daily inquiries from end customers. However, it directs those customers to suitable local installers. This approach keeps the residential sales process aligned with established market channels.
Looking ahead, Revolta expects to fully establish its sales network by 2027. The company plans to start with the German market. After that, it intends to expand into other European countries. Because the high-voltage storage system connects directly to the inverter rather than the grid, Revolta sees a smooth path toward broader market entry.
Why Revolta’s sodium-ion home battery stands out
Revolta’s new system combines modular capacity, compact dimensions, and high-voltage operation in one residential package. Homeowners can start with 2.0 kWh and scale up to 20 kWh. They also get more than 95% efficiency, low noise below 40 dB, IP65 protection, and a flexible installation process. Furthermore, the battery offers long standby capability and app-based commissioning.
Overall, the sodium-ion home battery marks an important residential energy storage launch from Germany in 2026. With its modular design and September rollout, Revolta is positioning itself for growth in Germany first and then across Europe.
