When failure is not an option: HyperStrong.

As a leading innovator in electrochemical energy storage, HyperStrong sets new standards in safety and efficiency. Where conventional systems reach their limits, HyperStrong is just getting started. At the heart of the systems is an artificial intelligence that permanently monitors the state of every single battery cell and detects thermal risks up to seven days in advance. Combined with state-of-the-art liquid cooling, HyperStrong is the ideal solution for critical infrastructure and demanding environmental conditions.

The HyperCube: maximum safety for your business

The HyperCube C&I is more than a storage system — it is your insurance against downtime and high energy costs. Built for the harshest environments (−30 °C to +55 °C), it defies heat, cold, salt and sand.

HYPERCUBE C&I II MAX
  • Proactive AI safety: the system warns proactively of thermal events ("thermal runaway") before they arise — with up to 7 days' lead time.
  • "Absolute Zero" cooling: the patented liquid-cooling concept keeps the temperature difference between cells below 3 °C, extending service life by up to 25 %.
  • All-in-one design: batteries, BMS, PCS and fire protection in one IP55/IP67-protected outdoor housing.

Grid scale

HyperBlock III: 5 MWh of power on just 20 feet

For utilities, solar parks and heavy industry, every square metre counts. The HyperBlock III is a technological masterpiece of densification: a novel design and integrated liquid cooling achieve market-leading energy density.

HyperStrong HyperBlock III

The advantages for large projects:

  • Massive space savings: store 5 megawatt-hours (MWh) in a single standard 20-ft container.
  • Falling LCOS: less floor space, fewer foundations and less cabling significantly reduce the levelized cost of storage.
  • Intelligent thermal management: homogeneous cooling delivers constant performance even at high C-rates and protects your investment long term.

Technology

What sets HyperStrong apart

AI safetyOrdinary storage systems react to faults. HyperStrong sees them coming. The AI analyses data patterns and warns of critical cell changes days in advance.
Liquid coolingAir cooling is yesterday. Liquid cooling enables higher packing densities, eliminates hotspots and ensures all cells age evenly.
Built for extremesDesert, coast or Alps: the housings are protected against dust, water and corrosion (IP55/C5) and operate reliably from −30 °C to +55 °C.
