Solutions

We enable the battery modules to be loaded individually, thereby ensuring that the available residual capacity is fully utilized. The functionality of conventional systems depends on the weakest link in the chain. Our STABL battery storage system therefore has an approximately 15 percent higher capacity over a period of ten years.

Two battery modules are redundant per phase per individual system. The cabinet therefore has 6-fold redundancy (2 battery modules/phase * 3 phases * 1 individual system/cabinet). The full container has 36-fold redundancy (2 battery modules/phase * 3 phases * 6 individual systems/container). Even in the worst-case scenario - i.e. three battery modules in one string fail - this would only lead to the failure of one individual system. In this case, the performance and capacity of a full container would be reduced by one-sixth until the STABL service has replaced the corresponding modules. By monitoring the system remotely, the time of failure of each battery module can be precisely estimated. This allows us to replace battery modules before they actually fail.

The distributed inverter is equipped with sensors on each battery module. In accordance with the specifications, one measuring point for voltage, current and temperature is provided on each battery module and inverter module. This means that six sensors must be installed per battery module, as there are a total of 27 modules and individual systems. This results in a total of 972 fire protection-relevant measuring points per full container. False detections or non-detections are therefore ruled out. The STABL system is a safe solution for storage locations close to valuable infrastructure (hall, machinery, vehicle fleet, etc.). In comparison, conventional systems with little monitoring next to valuable infrastructure could be classified as "grossly negligent".

The STABL inverter is compatible with a wide range of batteries (different manufacturers, voltages, cell chemistries), so our replacement service is not dependent on stock levels or delivery times. We always keep a single type of battery in stock and this can be installed in any existing system as a "replacement battery module". This is crucial to ensure long-term reliability.

Our STABL battery modules are characterized by a distributed inverter and compatibility with different battery modules. This makes it possible to replace the battery modules as required. Due to the longer service life of the electrical system, operation of the storage system is guaranteed for decades.
