Residential sodium-ion batteries now on sale via Austria’s Accupower are bringing a new home energy storage option to the market. Accupower, based in Graz, Austria, has launched the Natec Home system for residential photovoltaic installations, backup power, and small business use. Moreover, the company says it developed and designed this domestic sodium-ion storage system entirely in Austria. As a result, the launch marks an important step for European battery manufacturing and home energy storage.
Residential sodium-ion batteries now on sale via Austria’s Accupower: key specifications
The Natec Home system offers a nominal capacity of 7.68 kWh and a power output of 3.8 kW. Therefore, it fits typical home storage needs while also supporting backup applications. In addition, users can connect up to 15 units in parallel. This setup allows larger storage configurations for collective self-consumption and for businesses that need reliable backup power.
Accupower has priced the system at €3,990. Consequently, the Natec Home sits in a similar price range to many conventional Lithium-ion home battery systems. For homeowners and small commercial users, this pricing may make sodium-ion storage a practical alternative in the current market.
Why Accupower’s residential sodium-ion batteries stand out
Accupower emphasizes thermal stability as a core feature of its sodium-ion technology. The Natec Home operates in temperatures from -30°C to +50°C. Even at sub-zero temperatures, it retains around 90% of its nominal performance. Therefore, the system can support outdoor installation in many environments without the need for heating or climate control.
The battery also carries an IP65 rating. As a result, it offers strong protection against dust and water ingress. This feature adds flexibility for installers and property owners who need reliable operation in varied conditions.
Furthermore, the company designed the system with long-term use in mind. Accupower estimates a service life of 20 to 25 years in residential applications. The battery can deliver 8,000 charging cycles while maintaining at least 80% residual capacity at the end of that period. Because of this, the Natec Home targets users who want durability as well as stable performance over many years.
Residential sodium-ion batteries now on sale via Austria’s Accupower with advanced battery management
Accupower supports the Natec Home with its own Battery Management System, or BMS. The company developed this system to monitor key battery functions continuously. For example, it tracks state of charge, protects against overcharge and over-discharge, manages thermal conditions, and handles data management. Therefore, the BMS plays a central role in maintaining battery health and operational reliability.
In addition, Accupower says it reached industrial maturity for its sodium-ion batteries in 2025 through industrial applications. It has now transferred that experience to the residential segment. This progression gives the Natec Home a stronger technical foundation and supports confidence in the system’s design.
Accupower Natec Home design and installation details
The Natec Home measures 80 cm in height, 22.7 cm in width, and 50 cm in depth. Accupower chose a design that prioritizes operational safety, thermal stability, and long service life. As a result, the product focuses on dependable performance for home and small business energy storage applications.
Because users can scale the system by connecting up to 15 units, installers can adapt it to different energy needs. For example, a single unit may suit a household with moderate solar storage needs. Meanwhile, multiple units can support larger properties, collective self-consumption setups, or businesses that require backup energy capacity.
Accupower expands its Sodium-ion Battery portfolio
Alongside Natec Home, Accupower has introduced another sodium-ion product called Natec X-Plore. The company targets this battery at small mobile applications such as light vehicles, boats, and caravans. This broader product range shows that Accupower is building a wider sodium-ion portfolio beyond residential storage.
Looking ahead, the company plans to launch industrial container-format solutions in mid-2026. These products, called Natec Store and Natec Store C20, will provide electricity supply for off-grid locations. Therefore, Accupower is extending sodium-ion technology across residential, mobile, and industrial energy applications.
Residential sodium-ion batteries now on sale via Austria’s Accupower in Europe’s battery market
Accupower began series production of its batteries in April 2025. With this move, the company joins the growing group of European manufacturers producing sodium-ion cells and batteries within the European Union. At the same time, interest in sodium-based storage is increasing across Europe. The European Economic and Social Committee has also highlighted sodium batteries in its work on EU industrial strategy.
Overall, Accupower’s Natec Home combines a 7.68 kWh capacity, 3.8 kW output, parallel scalability up to 15 units, operation from -30°C to +50°C, IP65 protection, and an expected 20 to 25 year service life. At a price of €3,990, the new system gives households and small businesses a clear new option in the home energy storage market.
