Flexibility and versatility in designing energy storage systems

  • ACE 300 makes it possible to divide the storage capacity into smaller sections, which facilitates its protection and decreases the impact of potential faults. For instance, in the case of a DC short-circuit, only a portion of the capacity is affected. This leads to more reliable energy production and better financial yield.
  • 1 to 4 DC inputs enable various storage configurations.

Supports the grid

  • The active power and reactive power generation capacities in ACE 300 ES are equal, which supports the needs of the grid.
