Storing solar energy

The Apollion Cube is our best attempt at squaring the circle: it’s a compact and high performance storage system with lithium-ion technology at an outstanding price/performance ratio.

Quality/ Safety

Hazard-free operation is guaranteed using tried and tested technology, integrated cell monitoring and a redundant safety concept. Like all our batteries, the Apollion Cube has also been certified by independent testing institutes.

The storage system is developed according to standards and tested by independent institutes, such as TÜV Rheinland. A 7 year pro-rata warranty gives your investment sufficient additional protection.

Performance characteristics

The Apollion Cube is a power pack in the form of a cube with a high quality design and 6.7 kWh of nominal storage capacity. In order to increase the capacity, up to 12 systems can be combined together to form a battery with over 80 kWh. Efficient operation is ensured through constant temperature control and high-speed charging capability.

With the Apollion Cube we do not only increase the flexibility and capacity of a storage system, but we give you full control. You can keep a constant eye on your system via PC, Tablet or Smartphone thanks to continuous performance monitoring. You can revert to a wide range of charge controllers by SMA. Other well-known systems give a wider range of possible configurations.
