Sodium-ion home battery systems are gaining attention in residential energy storage. Revolta, a German startup, has introduced a high-voltage sodium-ion home battery for household use. The company designed the system for flexible capacity, simple installation, and strong efficiency. As a result, the new product adds another option for homeowners who want compact home energy storage in 2026.
Sodium-Ion Home Battery Design and Capacity
Revolta built its sodium-ion home battery around modular 2.0 kWh battery units. Each module stores 2.0 kWh of energy. Moreover, users can connect up to 10 modules in parallel. This setup increases total storage capacity to 20 kWh. Therefore, homeowners can size the system to match different energy needs.
The company also kept the physical design compact. Each battery module measures 284 mm × 186 mm × 260 mm. In addition, each unit weighs 19 kg. This compact format helps installers handle the modules more easily. It also supports flexible placement in residential settings.
Revolta allows a freely adaptable module configuration. Consequently, installers can scale the battery system according to household demand. Smaller homes may use fewer modules. Larger homes, by contrast, can use more modules to reach higher storage capacity.
Sodium-Ion Home Battery Specifications
Revolta lists several key performance figures for its sodium-ion home battery. According to the company datasheet, the system offers an energy density of 105 Wh/kg. It also operates at a nominal voltage of 450 V DC. These figures position the product as a high-voltage residential storage solution.
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 system gives homeowners a clear performance window for daily energy use and storage management.
The battery system achieves efficiency above 95%. That figure stands out because efficiency plays a major role in residential storage performance. Higher efficiency means the system can retain more usable energy during charging and discharging cycles. As a result, homeowners can make better use of stored electricity.
Revolta also designed the system for quiet operation. The company specifies noise emissions below 40 dB. Furthermore, standby losses remain very low. The battery can stay in standby for more than one year without needing a recharge. This feature supports long-term flexibility for household installations.
Sodium-Ion Home Battery Protection and Installation
Revolta equipped the sodium-ion home battery with an IP65 protection rating. Therefore, the system offers solid protection against dust and water ingress. The company also says the unit holds several certifications, which adds to its residential readiness.
Installation is another major focus. Revolta designed the system for simplified setup. A control unit connects the battery to the inverter and provides the required interface. In addition, the company plans to keep expanding inverter compatibility as more manufacturers complete approvals.
The commissioning process uses what Revolta describes as a plug-and-play over-the-air setup. Installers can complete this process through the company smartphone app or by Bluetooth connection. As a result, the setup process becomes faster and more convenient for residential projects.
Sodium-Ion Home Battery Market Launch in Germany
Revolta presented the sodium-ion home battery at The smarter E trade fair in Munich. The company plans the official market launch for September 2026. At the same time, several pilot projects are already in preparation. These early projects should help demonstrate the system in real residential applications.
The company says it is receiving daily inquiries from end customers. It usually directs those customers to suitable local installers. Meanwhile, Revolta is building its sales network through the traditional three-tier distribution model. That model moves products from wholesalers to installers. The company is already in early talks with distributors, according to its spokesperson.
Revolta expects to complete its sales network by 2027. First, it will focus on the German market. After that, it plans to expand into other European countries. Because the high-voltage storage system connects directly to the inverter instead of the grid, the company sees a smooth path for broader market entry.
Why Revolta’s Sodium-Ion Home Battery Matters
Revolta’s new sodium-ion home battery combines modular capacity, compact dimensions, and high-voltage operation in one residential storage product. It offers 2.0 kWh per module and up to 20 kWh total capacity. It also delivers more than 95% efficiency, a 450 V DC nominal voltage, and quiet operation below 40 dB.
Just as importantly, the system supports simple installation and scalable design. Therefore, it fits a wide range of home energy storage needs. With its September 2026 launch approaching, Revolta is positioning its sodium-ion home battery as a notable new option for the German residential storage market.
