The high voltage storage system ensures a stable main grid power supply. In addition to storing excess energy and the ability to discharge this energy back into the grid at full inverter capacity, features such as voltage balancing and the highly dynamic grid frequency regulation, make the xelectrix Power Box the optimal solution for grid operators and the energy balancing market. Modular design and the ability to Multirack means that power and storage capacities can be optimized to meet differing requirements.
