Maxxen, the Swiss-based energy storage manufacturer, is actively accelerating Europe’s energy transformation with fully operational, intelligent, and modular energy storage solutions. With a carbon-neutral, 20,000 m² vertically integrated facility in Aydin, Türkiye, at the gate of Europe; the company combines Swiss engineering precision with European manufacturing excellence, offering utility-scale and commercial & industrial (C&I) client's reliable systems that are built, delivered, and supported within Europe.

From day one, Maxxen has focused on solving real-world energy challenges through storage technologies that are scalable, compliant, and funding-ready. Backed by a $25 million industrial investment and a multi-GWh production roadmap, Maxxen currently exports more than 70% of its production across Europe and maintains a strong presence in key markets including Spain, Germany, Italy, the UK, Eastern Europe, and Turkey.

Custom-engineered solutions that meet “Made in Europe” requirements across all EU grants

Maxxen stands out for its ability to design and deliver fully customized energy storage systems that meet the technical, traceability, and regulatory requirements of public funding programs in Spain and across the European Union.

Whether in IDAE calls in Spain, PNRR tenders in Italy, or other national schemes tied to REPowerEU and NextGenEU objectives, Maxxen consistently fulfils "Made in Europe" criteria related to local content. This is possible thanks to its strategic collaborations with EU-based EMS and PCS manufacturers, including top-tier partners located in Spain and other member states.

Clients working with Maxxen benefit from a fully compliant, grant-ready storage solution, with all required documentation, EU-based component sourcing, and technical features like grid-forming and NIS2-compliant cybersecurity built in from the start.

Smart storage must be powerful, trusted, and accessible

According to Ruben Valiente, Managing Director of Maxxen Energy AG: “Europe’s energy transition depends on storage — not just batteries, but full solutions that are smart, secure, and scalable. At Maxxen, we deliver exactly that. We support public and private developers alike with systems that are optimized not only for performance, but also for compliance with national and EU-level programs. Our vision is clear: to accelerate clean energy with trust, technology, and European value.”

From 250 kWh to 5+ MWh: A complete portfolio for real-world applications

Maxxen’s product range includes grid-scale BESS units exceeding 5 MWh, ideal for renewable integration and grid balancing. The company also offers modular behind-the-meter solutions starting at 250 kWh — suited for industrial self-consumption and off-grid applications.

Each system is engineered for flexibility, fast deployment, and long-term reliability.

Circular and sustainable by design

Sustainability is embedded in Maxxen’s model — from carbon-neutral manufacturing to full lifecycle support. All systems come with long-term maintenance and warranty, and are designed for second-life reuse and recycling, ensuring minimal environmental impact.

Headquartered in Zurich, Maxxen operates through a multi-hub structure with locations in Amsterdam, Istanbul, and Izmir, allowing the company to manage sales, aftersales, warranties, cybersecurity, logistics, and service across Europe with speed and precision. This structure ensures local responsiveness while upholding the highest standards of Swiss quality and European integration.

Maxxen is not just another battery provider — it's your European partner for grant-ready, future-proof energy storage, reducing the lead time of delivery and battery degradation.
