- **Switching time**: an automatic switchover to the backup power supply in less than 10 ms during a power outage
- **Management**: choice of different energy modes such as self-consumption, peak shaving, and automatic optimization based on the cheapest hours
- **Mounting**: flexible installation possible both indoors and outdoors thanks to the IP65 protection rating
- **Efficiency**: a high maximum efficiency of 96.5% and a design lifespan of at least 6000 cycles


## Three-phase flexibility and smart energy control


The system supports a 100% unbalanced load across the three phases, ensuring a stable power supply for the loads in the building. Thanks to the integrated AI mode, the software anticipates fluctuating electricity tariffs. This allows the installation to charge or discharge automatically at the most economical moments to lower energy costs. The components are designed for clear mounting and can be easily integrated into both new and existing installations.


If more storage capacity is required in the future, you can easily expand the system by connecting up to 32 modules in parallel for a total of 327.68 kWh. The built-in self-heating also ensures that the battery charges without problems even at low ambient temperatures down to -5°C. Check the current stock status and order directly online.
