As one of the world’s top five energy storage system manufacturers and a long-standing BNEF Tier 1 supplier, REPT BATTERO used Intersolar Europe 2026 to move beyond individual product releases and instead present a fully integrated energy storage ecosystem. Rather than focusing on single hardware items, the company showcased a comprehensive suite that spans technological innovation, storage equipment, global project delivery and EU regulatory compliance. The offering is built to tackle three persistent industry pain points: technical deployment hurdles, financing obstacles and cross-border compliance burdens for storage developers, asset owners and investors.

New Chemistry: Wending® 320Ah Sodium-ion Cell Innovation

Broadening its technology portfolio beyond lithium iron phosphate, REPT BATTERO unveiled the advanced Wending® 320Ah sodium-ion cell to unlock diversified, resource-independent storage solutions. Leveraging the proprietary Wending® structural design and tailored cathode-hard carbon anode systems, the cell delivers ≥97% energy efficiency, an ultra-long lifespan of 20,000+ cycles, and industry-leading wide temperature adaptability from -50℃ to 60℃, retaining over 87% capacity at extreme low temperatures. Sodium materials feature abundant global reserves and geographically diversified supply chains, easing raw material supply risks. The cell also demonstrates superior thermal safety: its thermal runaway peak temperature is 124℃ lower than standard LFP cells, and it passes stringent nail penetration, overcharge and thermal abuse tests without fire or explosion. This creates a high-reliability alternative for cold-region, off-grid and long-duration storage deployments worldwide.

Power Advance: High-Capacity, High-Safety Powtrix® ESS

At the core of REPT BATTERO’s integrated offering sits the newly launched Powtrix® 6.9 MWh 20-foot liquid-cooled containerized energy storage system, engineered for medium and long-duration utility storage scenarios. Built on a 1500V DC LFP platform with 648Ah large-capacity cells, the system achieves ≥96% round-trip efficiency and over 10,000 charge-discharge cycles to maximize asset revenue. Optimized for global logistics and on-site construction, the design reduces equipment quantity, site labour hours and land footprint by nearly 30% compared with legacy 5 MWh products. The unit features balanced liquid cooling, AI-powered multi-layer risk early warning, and full alignment with NFPA 855-2026 fire safety codes, together with cross-regional certifications for EU, UL and AS/NZS markets. Flexible PCS matching architectures support seamless integration with European local inverters and grid-forming medium voltage skids to fit diverse project layouts.
