Storage

EEI designs and manufactures a complete range of PCS and Energy Storage solutions necessary to achieve the goal of an intelligent and more flexible network and a better and more efficient use of energy sources.

All EEI PCS are designed to operate in parallel with the network or in off-grid mode, performing a wide range of functions with the aim of improving the availability and quality of the power supply, reducing the costs for the supply of electricity.

Main functions of the PCS Energy Storage EEI are:

  • Peak-shaving and load leveling
  • Frequency regulation
  • Power supply in case of power failure
  • Management of active and reactive power
  • Connection and integration of renewable and non-renewable energy sources

EEI off-grid systems find excellent use in all those applications where the network is weak or absent and where it is important to guarantee continuity of electrical service with good network quality. EEI can supply complete systems to be able to supply loads from remote areas or with unstable networks where the main source of energy and back-up power is now diesel generators and through EEI’s Energy Storage solutions the user can reap enormous benefits by reducing its fuel consumption and improving the quality and stability of the energy supply.
