Revolta AG Unveils Sodium-Ion High-Voltage Home Battery at Intersolar Europe 2026

Revolta AG, a German energy storage company, announced the launch of a sodium-ion-based high-voltage home battery system at Intersolar Europe 2026, scheduled for June 23–25, 2026, in Munich. The modular system, operating at 450 volts, offers storage capacities ranging from 2.2 to 22 kWh, using sodium-ion cells instead of lithium-ion technology.

What Makes This Battery Different?

Revolta’s new system leverages sodium-ion cells, which the company claims provide “high thermal stability” and reduced fire risk compared to lithium-ion batteries. Julian Mattheis, CEO of Revolta AG, highlighted that sodium-ion cells inherently resist overheating, a critical safety feature for residential applications. The battery also includes a CO sensor, acoustic alarm, and pressure relief valve for added safety.

How Does the Voltage Multiplier Technology Work?

The core of the system is a voltage multiplier technology developed by Revolta. A high-frequency transformer boosts the voltage by 50 times, enabling a compact design. Henk Oldenkamp, CTO of Revolta AG, stated this reduces system complexity and electronic components, allowing the battery to use just three large-format cells per 2.2 kWh unit, compared to the dozens or hundreds used in conventional systems.

What Are the Technical Specifications?

The battery operates at a nominal voltage of 450 volts and is modular, with single units ranging from 2.2 to 22 kWh. Each module integrates a control unit, enabling linear scalability without centralized management. The system’s compact size and lightweight design position it as one of the smallest high-voltage home storage solutions in its class, according to Revolta.

Why Is This Significant for the Solar Market?

The residential solar storage market has been dominated by lithium-ion technology, but sodium-ion batteries are gaining attention for their lower cost and abundance of raw materials. Revolta’s entry could diversify options for homeowners, though its success will depend on cost-effectiveness, availability, and long-term performance. Industry analysts note that sodium-ion is still in early adoption phases, with limited real-world data compared to lithium-ion.

What’s Next for Revolta AG?

Revolta plans to showcase the battery at Intersolar Europe 2026, where it will detail its performance metrics and pricing. The company has not yet released commercial availability dates, but the event marks a key milestone in sodium-ion technology’s push into residential energy storage. Revolta AG has previously focused on industrial energy solutions, making this its first foray into the home market.
